Description

I. Field of technology to which the invention relates

The invention relates to the field of electrical engineering and nuclear energy. Power supply of aircraft is carried out from generators of direct and alternating current of various voltage or current values. There are different demands on the power quality of alternators. For example, heating systems do not place high demands on the quality of electricity, while a number of other devices place high demands on the quality of electricity. The form of the voltage generated by these generators should be close to a sinusoidal form, the level of harmonics should not exceed the permissible value. The proposed device is designed to generate a sinusoidal voltage using modules from power generating elements (EGE) of a nuclear power plant. Thermoelectric, thermoemission or thermo-electrochemical converters can be used as EGE, with the help of which the energy generated by a nuclear power plant (NPP) is converted into electrical energy. One of such installations is described in [1]. In the described generator, obtaining the output voltage of the device, in its shape approaching a sinusoidal function, is based on the approximation of a sinusoidal function by a sequence of 24 impulse functions. The approximation of a sinusoidal function used in the device by a sequence of 24 impulse functions makes it possible to improve the quality of the voltage generated by the generator, which is close in shape to a sinusoidal function of time, to reduce the number and amplitudes of higher harmonics that distort the sinusoidal voltage waveform, to increase the energy performance of the installation by eliminating or reducing the energy of higher harmonics , to lower the requirements for higher filters and, as a result, to lower the cost of the generator.

II. State of the art

II.1 Comparison with prior art

In power supply systems for spacecraft (SC), converters (inverters), including step-up transformers, or electric machine generators are currently used to obtain high-voltage direct or alternating voltage. The high-voltage consumers of the spacecraft include electric propulsion motors (ERE). Their operation requires a voltage reaching several tens of kilovolts in magnitude. The weight and size characteristics of devices containing a step-up transformer on a ferromagnetic core or electric machine generators are large and range from γ = (3 ... 5) kg / kW to γ = 30 kg / kW. The characteristics of the step-up transformer used in the spacecraft power supply system are given in [1]. Thermoelectric, thermo-electrochemical (TECG) and thermoemission converters are used to convert thermal energy generated by a nuclear reactor into electrical energy. In such converters, electrical energy is generated by separate power generating elements (EGE). Each EGE generates direct current electrical energy of a small voltage value, of the order of 1 V. To obtain the voltage and current of the required value, a series-parallel connection of the EGE is used. To obtain the required value of the constant voltage, a serial connection of the EGE is used, to obtain the required value of the current, a parallel connection of the EGE is used. To obtain the required constant voltage and current, individual EGEs are combined into modules. In each EGE module, they are connected in parallel in groups to obtain the required current value; to obtain the required voltage value, individual EGEs, or groups with a parallel EGE connection, are connected in series. This is shown in the figure in FIG. 1. In the figure of FIG. 1 shows a parallel - serial connection of the EGE. A group of k parallel-connected EGEs with a current Ie provides the module current Im = k⋅Ie, a series connection of p such groups provides the module voltage Um = p⋅Ue. As a result, the ME module will have nominal parameters - voltage Um and current Im.

Figure 1. Series-parallel connection of EGE

The parameters of one EGE are given in Table 1, according to the data published in [1].

In total, in the thermo-electrochemical generator described in [1], 1344 EGE were required to obtain an electric power of 30 kW (or 90 kW at an increased frequency). Using the transformer described in [1], the voltage was increased from 120 V to 3000 V.

To improve the mass-dimensional characteristics of the spacecraft power supply system, it is advisable to obtain a high AC voltage using the proposed semiconductor generator. The generator described below makes it possible to obtain a high quality AC voltage as a result of combining individual EGEs into modules and switching modules to obtain the required values of alternating voltages and currents.

II.2 Purpose of the invention.

The aim of the invention is to develop a device for generating an alternating voltage, the shape of which most fully approaches the sinusoidal one due to the approximation of the sinusoidal function by a sequence of impulse functions, consisting of 24 pulses. For this, modules are used that contain a serial-parallel connection of the EGE. In this case, the primary source of energy is the nuclear power plant. With the help of EGE, the thermal energy of the nuclear power plant is converted into electrical energy of constant voltage, which is then converted into electrical energy of alternating voltage using the proposed device. The conversion is carried out using pulse technology and semiconductor switches. Due to the use of impulse technology and semiconductor switches, the mass-dimensional characteristics of the device are improved. A characteristic of the proposed generator is the use of a sequence of voltage pulses of the same magnitude and polarity, the number of which is 24 per period of the sinusoidal function. To obtain pulses of negative polarity, a pulse commutator is used.

II. 3. Inventive level.

The proposed device for generating alternating high-voltage sinusoidal voltage using nuclear power plant energy differs from devices in which alternating high-voltage sinusoidal voltage is obtained as a result of using inverters and step-up transformers, or using electric machine generators [2, 3] in that:

- sinusoidal voltage is generated as a result of approximation of the sinusoidal function of the output voltage by a sequence of 24 pulse functions;

- voltage pulse functions are generated by modules, each of which contains a series-parallel connection of the EGE to obtain the required voltage and current of the module. Module voltage and current are equal to Um and Im;

- the number of impulse functions on the period of the sinusoidal function is set by the control unit. The voltage at the generator output is formed by a set of rectangular voltage pulses of a given value and the same duration TI, which are repeated at a given frequency. The number of pulses in the period T is equal to n = T / TI. Further, the value of the number of pulses in the period equal to n = 24 is taken. The value of the voltage of each pulse in the interval of a quarter of the period T / 4 is a multiple of the value of the voltage of one power supply (module) equal to E1, i.e. E ₂ = 2E ₁ , E ₃ = 3E ₁ , E ₄ = 4E ₁ , E ₅ = 5E ₁ , E ₆ = 6E ₁ . An approximation of a sinusoidal function by a sequence of 24 impulse functions is shown in the figure of FIG. 2;

- the amplitude values of the pulses are multiples of the module voltage. For example, if the voltage of the module is Um, then for n = 24 the amplitude of the first and twelfth pulses is taken equal to E ₁ = E ₁₂ = Um, the amplitude of the second and eleventh pulses is taken equal to E ₂ = E ₁₁ = 2E ₁ , E ₃ = E ₁₀ = 3E ₁ , E ₄ = E ₉ = 4E ₁ , E ₅ = E ₈ = 5E ₁ , E ₆ = E ₇ = 6E ₁ . Similar relationships hold for pulses approximating the negative half-wave of a sinusoidal voltage. Multiple values of pulse voltages are obtained as a result of serial connection of modules;

- the use of a pulse switch allows one to approximate the positive and negative half-waves of a sinusoidal voltage;

- To connect power supplies (modules) to the output poles of the generator, a switching unit is used, with the help of which voltages of the required magnitude and polarity are connected to the output of the device in the sequence specified by the control unit.

III. Disclosure of the essence of the invention

III.1 Approximation of a sinusoidal function by a sequence of impulse functions

In the figure of FIG. 2 shows the approximation of a sinusoidal function by a sequence of impulse functions, when the number of impulse functions on the period of the sinusoidal function T is equal to n = 24.

FIG. 2 Approximation of a sinusoidal function by a sequence of impulse functions for n = 24

FIG. 2 shows a segment of a sinusoidal function with an amplitude Em in the interval T = 0 ... 2π ;. The sinusoidal function in this interval is approximated by a sequence of n = 24 impulse functions with multiples of the impulse amplitudes. For the device shown in FIG. 2 approximations E ₁ = Um, Ek = kE ₁ , where k = 2… 6, E ₁ is the amplitude value of the first pulse, Um is the voltage of one power generating module. To approximate the negative half-wave of a sinusoid, the amplitude E ₁₃ = E ₂₄ = -E ₁ , the amplitude E ₁₄ = E ₂₃ = -2E ₁ , E ₁₅ = E ₂₂ = -3E ₁ , E ₁₆ = E ₂₁ = -4E ₁ , E ₁₇ = E ₂₀ = -5E ₁ , E ₁₈ = E ₁₉ = -6E ₁

In Table 2, in accordance with the figure in FIG. 2 recorded the values of the pulse amplitudes for each of 1 ... 24 intervals of approximation.

III.2 Block diagram of the device

The block diagram of the device is shown in the figure in Fig. 3.

Figure 3 Block diagram of the generator

In the figure of FIG. 3 shows the blocks BU, BKI, BKP, BME, input and output poles, with the help of which the blocks are connected to each other and to external devices. The figure shows the following device blocks:

III.2.1. Control unit BU. The control unit provides a cyclic, with a given period T, alternate supply of control pulses that control the opening of the electronic power switches KS1 ... KS6 located in the BKI switching unit. With the help of the control pulses generated by the control unit, the polarity of the pulses at the output of the device is also controlled using the controlled keys K1 ... K4 located in the BKP unit. The input poles of the block are 6 ₁ and 6 ₂ ;

III.2.2. Pulse switching unit (BKI). The pulse switching unit (BKI) provides connection of constant voltages of the required value E ₁ ... E ₆ at the time intervals specified by the control unit with the polarity required to obtain a sinusoidal function to the output terminals of the switching unit 10 ₁ and 10 ₂ . Constant voltages E1..E6 come from the power supply unit BME from poles 11 ₁ ... 11 ₆ and "ground" to the controlled keys KS1 ... KS6. Output for the BKI unit are poles 10 ₁ and 10 ₂ , with the help of which the unit is connected to the BKP unit.

III.2.3. Polarity switching unit (BKP). The block provides positive or negative polarity of the output pulses to approximate the positive or negative half-wave of a sine wave. Poles 10 ₁ and 10 _{2 the} unit is connected to the BKI unit, the output poles of the unit are poles 12 ₁ and 12 ₂ . These poles are output for the device as a whole.

The operation of the unit is controlled by means of control pulses coming from poles 8 ₁ … 8 ₂₄ of the control unit CU. III.2.4. Block of electrical modules (BME). The block includes six series-connected electrical modules МЭ1 ... МЭ6 with voltage Um and rated current value Im each. The pole of the ME1 module with negative polarity is connected to ground, the ME1 ... ME6 modules are interconnected by poles 11 ₁ ... 11 ₆ , the BME unit is connected to the BKI switching unit.

III.3 Control unit

The control unit CU, figure Fig. 4, is designed to generate control pulses as a result of creating a sequence of rectangular pulses of a given duration 77. Control pulses from poles 8 ₁ ... 8 ₂₄ are fed to the control electrodes of the power switches KS1 ... KS6 of the BKI unit and to the electrodes of the same name of the BKP unit for controlling the open or closed state of the keys K1 ... K4. With the help of keys K1 ... K4, pulses with positive and negative polarity are formed. The GTI clock pulse generator (1) generates a sequence of pulses cyclic with a period T. The value of T is equal to the period of the sinusoidal function. The number of pulses in the period T is equal to n, the duration of one pulse is TI. The values of n and TI are selected based on considerations of ensuring the required approximation error of a sinusoidal function by a sequence of rectangular impulse functions and the cost of implementing the device. With increasing n and decreasing TI, the error decreases and the cost increases. In the device under consideration, the number of pulses per period is equal to n = 24. Using the electronic keys KS1 ... KS6 located in the BKI pulse switching unit, the EMF sources E ₁ ... E ₆ generated by the ME1 ... ME6 power supply modules are connected at the times specified by the control unit to output poles of the switching unit 10 ₁ and 10 ₂ . Switching is carried out in the open state of the key. The duration of the open state of each key KC1 .... KS6 is equal to TI. The amplitudes of the EMF pulses for n = 24 are given in Table 2.

A schematic diagram of the control unit is shown in the figure in Fig. 4. Figure 4 Schematic diagram of the control unit

The block is implemented on elements 1-7. It contains a GTI clock pulse generator (1), a logical element AND (2), a counter 3 of the number of pulses at a period T of a periodic function, a comparison circuit 4, a register 5, a decoder 7 with output poles 8 ₁ ... 8 _n . In the figure of FIG. 2 number n = 24. The device is started by giving a signal at input 6 ₁ . At input 6 ₂ using register 5, the code of the number of time intervals n = 24 is written. When the number of pulses at the output of counter 3 becomes equal to the number written in register 5 and equal to 24, the comparison circuit 4 generates a rectangular pulse. This pulse goes to the second input of counter 3 and resets it to zero. As a result, a periodic process occurs with a given period T = nTi. In this expression, Ti is the duration of one pulse generated by the GTI generator (1).

The GTI output (1) is connected to the first input of the AND element (2), the second input of which is connected to the first input 6 of the device, and the output to the first input of the counter 3, the output of which is connected to the input of the decoder 7 and to the input of the comparison circuit 4, the output of the circuit comparison is connected to the register 5. The output of the counter 3 is connected to the input of the decoder 7. Each pulse arriving at the input of the decoder 7 from the counter 3 causes a pulse to appear at the next output of the decoder. So, the first pulse causes the appearance of a pulse at the first output of the decoder 8 ₁ , the second pulse coming from the counter 3 to the input of the decoder, causes the appearance of a rectangular pulse at the second output 8 _{2 of the} decoder. This process continues up to 24 pulses. Pulses from poles 8 ₁ ... 8 ₂₄ are fed both to the input of the BKI unit and to the input of the BKP unit.

III.4 Pulse switching unit BKI. The BKI circuit is shown in Figure 5. Fig. 5 Diagram of the pulse switching unit

With the help of the BKI switching unit, the voltages E ₁ ... E ₆ generated by the BME unit are supplied at the appropriate time intervals to the output poles of the unit 10 ₁ and 10 ₂ . Voltage E1 is supplied to the output poles of the unit when the KC1 key is closed in the first, twelfth, thirteenth and twenty-fourth time intervals of duration TI. From the poles 8 ₁ , 8 ₁₂ , 8 ₁₃ , 8 ₂₄ of the control unit, signals are sent through diodes D ₁ , D ₂ , D ₃ , D ₄ to the control electrode of the key KC1. Voltage E2 is supplied at the interval of action of the second, eleventh, fourteenth and twenty-third pulses to the output poles 10 ₁ and 10 ₂ in the open state of the KS2 key. The control of the open state of the key KS2 is carried out as a result of the receipt of control signals from the poles 8 ₂ , 8 ₁₁ , 8 ₁₄ , 8 ₂₃ by means of diodes D ₅ , D ₆ , D ₇ , D ₈ to the control electrode of the key KS2. The numbers of the control pulses arriving at the control electrode of the key are set in accordance with Table 2. From Table 2 it follows that the voltage E ₂ will be the same in modulus for the second, eleventh, fourteenth and twenty-third pulses. Similarly, the control of the transmission of pulses with amplitude modulus values of voltages E ₃ ... E _{6 is} carried out. These voltages are also supplied at appropriate time intervals to the output poles 10 ₁ and 10 ₂ of the BKI unit.

III.5 Pulse polarity switching unit (PCP). To form a sequence of pulse functions at the output of the generator, which approximates the positive and negative half-waves of the sinusoidal function of the output voltage, a pulse polarity switching unit is used. The BKP circuit is shown in the figure in Fig. 6. The figure shows the generator load with resistance R, which is connected to the output poles of the unit 12 ₁ and 12 ₂ .

FIG. 6 Diagram of the block for switching the polarity of pulses of the BKP

The block includes keys K ₁ ... K ₄ , the open state of which is controlled by supplying control impulses to the control electrodes of the keys. When a signal arrives at the control electrode of the key, it opens and passes a voltage pulse taken from the input poles 10 ₁ and 10 ₂ to the output poles of the generator 12 ₁ and 12 ₂ . To transmit pulses with positive polarity, the keys K ₁ and K ₃ are opened, the keys K ₂ and K ₄ are closed. Pole 101 in this case connects to pole 12 ₁ and pole 10 ₂ connects to pole 12 ₂ . To form pulses with negative polarity at the output of the device, the keys K ₂ and K ₄ are opened, the keys K ₁ and K ₃ are closed. Pole 10 ₁ in this case is connected to pole 12 ₂ , and pole 10 _{2 is} connected to pole 121. Keys K ₁ and K _{3 are} controlled by control pulses coming from poles 8 ₁ ... 8 ₁₂ of the control unit through diodes DK ₁ ... DK ₁₂ . Keys K ₂ and K ₄ are opened by control pulses coming from poles 8 ₁₃ … 8 ₂₄ of the control unit through diodes DK ₁₃ … DK ₂₄ . Control signals go to the control electrodes of the keys.

The graphs of the voltages U _ctrl and U _ctr2 supplied to the control electrodes of the switches are shown in the figure in FIG. 7.

FIG. 7 Control voltage graphs

In the figure of FIG. 7, the amplitudes of the control pulses are taken equal to 1 and 0.

III.6 Block of power supply modules ME

The block of power supply modules (BME) consists of modules ME ₁ ... ME ₆ , connected in series. Each module consists of series-parallel connected EGE power supply elements, as shown in the figure in FIG. 1. Each module is characterized by the module voltage Um and the rated current of the module Im. The pole of the МЭ ₁ module with negative polarity is connected to the "ground" terminal, which is common for the entire device. From the positive pole of the module ME ₁ through pole 11 _{1, the} voltage E ₁ = Um is supplied to the input of the BKI pulse switching unit. This pole is also connected to the negative pole of the ME ₂ module. Voltage E ₂ = 2E ₁ from pole 11 _{2 is} fed to the input of the BKI unit, as shown in the figure in Fig. 5. The remaining modules ME ₂ ... ME ₆ of the BME unit are connected in a similar way.

V. Implementation of the invention

Description of the operation of the device. In the initial state, the code of the number of time intervals n is written on the register 5 at input 62. The period of the sinusoidal function T is divided into this number of intervals when the sinusoidal function is approximated by a sequence of impulse functions.The operation of the device starts after a start signal is applied to the input 61 of the logical element AND (2). After the start signal is applied, pulses from the output of the clock pulse generator 1 through the open element I (2) begin to enter the input of the counter 3. The code from the output of the counter 3 enters the input of the decoder 7. At the output of the decoder, a single signal appears only at one of its n outputs. A single signal at the i-th (i = 1 ... n) output of the decoder 7 is fed to the input of the switching unit by means of one of the poles 8i, i = 1 ... n, which is connected to the control electrodes of the controlled keys KС ₁ ... KС ₆ . The connection is made through one of the diodes.

For key KC ₁ these are diodes D ₁ … D ₄ , for key KC ₂ these are diodes D ₅ … D ₈ . For the KC ₃ key, these are diodes D ₉ ... D ₁₂ . For the KS ₄ key, these are diodes D ₁₃ ... D ₁₆ . For the KS ₅ key, these are diodes D ₁₇ ... D ₂₀ . For the KS ₆ key, these are diodes D ₂₁ ... D ₂₄ . So, the control pulse from the pole 8 ₁ in the first time interval is fed to the diode D1 and then to the control electrode of the key KS ₁ . On the same control electrode in the twelfth time interval from the pole 8 ₁₂ , a control pulse is supplied through the diode D ₂ , in the thirteenth time interval from the pole 8 ₁₃ through the diode D ₃ and in the twenty-fourth time interval from the pole 8 ₂₄ through the diode D ₄ . When a signal arrives at the control electrode, the KC ₁ key opens and passes the voltage E1, which comes from pole 11 ₁ of the BKI unit. Similarly, the key KS2 is opened when a control pulse arrives in the second time interval from pole 8 ₂ through diode D ₅ , in the eleventh time interval the pulse arrives from pole 8 ₃ through diode D ₆ , in the fourteenth time interval from pole 8 ₆ through diode D ₇ , in the twenty-third time interval from pole 8 ₈ through diode D ₈ . When the public key KS ₂ voltage E ₂ is transmitted to the pole ₁₁ February output device block. The control of the open state of the keys KS ₃ ... KS ₆ and the transmission of pulses with voltages E ₃ ... E ₆ from the BME unit to the poles 10 ₁ , 10 ₂ of the BKI unit is carried out in the same way.

By means of the keys K ₁ , K ₃ or K ₂ , K _{4, the} voltages from the poles 10 ₁ , 10 ₂ are transmitted to the output poles of the generator 12 ₁ and 12 ₂ , either directly or inversely. Keys K ₁ and K _{3 are} either on or off at the same time. In the on or off state, they are for a time interval equal to T / 2. Pi direct transmission of pulses, control is carried out as a result of supplying control pulses from poles 8 ₁ ... 8 ₁₂ of the control unit through diodes DK ₁ ... DK ₁₂ to the control electrodes of keys K ₁ and K ₃ . _{Keys K 2} and K ₄ work in a similar way. When the pair of keys K ₁ and K ₃ is in the on state, the pair of keys K ₂ and K ₄ is in the off state and vice versa. The control of the open or closed state of the keys K ₂ and K _{4 is} carried out as a result of supplying control pulses from poles 8 ₁₃ ... 8 ₂₄ by means of diodes DK ₁₃ ... DK ₂₄ to the control electrodes of keys K ₂ and K ₄ . The time dependence of the period T of the control pulses U _ctrl , which are fed to the control electrodes of the keys K ₁ and K ₃ , and the control pulses U _ctr2 , which are fed to the control electrodes of the keys K ₂ and K ₄ , are shown in the figure of FIG. 7. Control pulses arrive with a shift in the time interval T / 2. This makes it possible to form at the output poles 12 ₁ and 12 ₂ half-waves with positive and negative values, which approximate the sinusoidal function of the output voltage.
