Description of the invention: [Technical field to which the invention pertains] The present invention relates to a power tracking system for a solar energy system and a method thereof, and more particularly to a system and method for generating electricity using solar energy. [Prior Art] Due to the high level of industrial development and the increase in population, the earth's energy is being consumed at an unprecedented rate. Some of the energy that propels up humanity for centuries will be exhausted after several generations. The earth's oil can only make us 4 to 5 years, natural gas is still about (9) years old, and uranium has 7 years of mineral deposits. The coal mine is long but only 2 years old. These short-term geniuses are insignificant for the long years of human civilization. The development of this new source will be urgent and necessary, and its renewable energy is human-energy hope. > Renewable energy refers to wind, solar, hydro, biomass, nitrogen, geothermal, ocean temperature, ocean waves and tides (10) _. A part of the renewable energy of the towel has a geographical area. i. T ’ Only solar energy is the most common energy for miniaturization. From a point of view, the solar moon has the following: (1), safe and reliable, (four) sound, no pollution, (2), = easy to directly cause the earth's greenhouse effect, (3), the required energy is available everywhere, no fuel consumption Mechanically rotating parts. (4), easy maintenance, long service life; short construction period 'size and size, (5), can be unmanned, no need to set up transmission lines, (6), low energy costs in remote areas, (7), convenient combination of disk construction and killing, etc. This is generally valued by the energy industry. ^Yang ▲ photoelectric conversion can be divided into three types, solar cells, solar radiation can decompose water for hair. Among them, large-scale power generation makes the most economical recording, while the 200827974 small and medium-sized ones should rely on the solar cells. A solar cell is a semiconductor material that is irradiated with solar energy to form a current on the surface of the semiconductor, which is stored as a direct current, converted or converted into an alternating current and connected to the grid for power supply. • The main key technologies used by solar photovoltaic energy are (A) solar cells (solar panel (B) maximum power tracking and acquisition (c) battery charging technology (d) discharge system technology. Solar cells are semiconductor processes, generally including single There are three types of crystal, polycrystalline and amorphous solar cells. In addition, flexible or money solar cells are also actively progressing. Currently, the maximum photoelectric conversion efficiency of commercial solar panels is below the worst. The maximum power tracking and acquisition is #界 Currently invests more people, and urgently needs to improve the key technology. The most important energy storage medium for small and medium-sized solar (four) system and large-scale solar power system operation is the battery. Solar battery charging technology is the key and cannot be The lack of - ring. And the discharge system technology with the increasing demand for solar discharge quality, more and more important importance. Solar energy is - ideal for renewable energy, with sunshine Wei, angle and [temperature generation The power of electricity has a lot of money. It means that it is too variably regenerating this source, and the energy of each point of energy can be turned into the most Power tracking, in order to obtain the most A energy converted by solar cells. - General Wei is presented in terms of electricity, current and time, and is the maximum power tracking and acquisition of solar energy with scaly scales. It is not linear with current, and it has a unique working curve due to temperature and temperature. As shown in the first figure, there are different electric (four) flow curves for strong, medium and weak sunshine. Then observe the power of the solar panel >1, as shown in the second figure, each working curve has a maximum power point, 6 200827974 ♦ that is the place to get the maximum energy of the solar panel. Through various maximum power tracking technology Tracking the maximum power voltage and current status of different time points with the environment, and quickly obtaining its energy injection system. Traditionally known maximum power tracking techniques include * A, voltage feedback method. B, power feedback method C, disturbance observation method, D, incremental conductance method, E, linear approximation method, f, actual measurement method, the most commonly used is "perturbation observation method", As shown in the third figure, the structure is simple and the measurement parameters are few, and it has been widely used in the solar maximum power system. The basic structure is to change the solar panel by periodically increasing or decreasing the load (5). (1) The end 赖 and the tracking calculus (2) The output power. The difference between the spectator and the 乂 , , , , 乂 乂 乂 乂 乂 乂 乂 乂 乂 乂 乂 乂 乂 乂 乂 增加 增加 增加 增加 增加 增加 增加 增加 增加 增加 增加 增加 增加 增加 增加(5) Make adjustments to the same trend; Conversely, if the output power becomes smaller, the direction of the county will be changed in the next two periods. Such repeated vibrations and observations will be closer to the maximum power point of the solar cell. "Perturbation observation" maximum power tracking method is the most important way to control the DC/DC converter (4)'s duty cycle. Longitudinal to achieve the power of the solar cell. When the maximum power is approached, the oscillation disturbance does not stop, and the succession oscillates around it. #Sunlight intensity, environment and temperature change, the sun, the maximum power point of the system operation changes immediately, the oscillation disturbance also responds immediately, and the new power point chasing 5 runs again. ' DC / DC transfer surface is * domain and capacitor circuit plus two _ with electronic switch, can use tilt, buck and buck-boost DC / DC converter, with just 7 200827974 (3) or PFM , pulse 5 hole number. By controlling the proportional time of the switch, the load at the output is adjusted to track the maximum power point. Ultra-Electric Valley has excellent energy storage characteristics, and its use in solar installations can increase efficiency, reduce maintenance, and maintain operating time. The solar charging system described in U.S. Patent No. 2004/_982 uses a double-layer capacitor (i.e., ultra-capacitance) as an energy storage device, and is regulated by a DC/DC converter to track the maximum power point. Supercapacitors play a role in replacing batteries in many electronic power applications, such as RTC memory and solar LED lights. In the past, ultra-capacitor energy density was much lower than that of batteries, and applications in energy storage were critical. Shouting a few years, the ultra-capacitor energy density has increased rapidly, and the battery is everywhere. The DC system of the solar system is gradually considering the placement of supercapacitors, especially the j max = rate point tracking. US patent employment / 〇 3i2i 〇 2 also proposed efficient solar moon b system first maximum power charging to ultra-capacitor circuit 'designed - the circuit can be used for maximum power chasing 疋 power charging super capacitor. In addition, the supercapacitor is divided into two types: the energy release type and the transient work paste, and the (10) energy storage is dominant. Because it is a storage device, its use of life and reliability is much higher than that of a chemically reactive battery. Then it can provide powerful power, the characteristics are similar to the capacitor ^, with instant burst. The power amplifier supercapacitor is connected in series with the solar panel. Following the TM, the rapid response characteristics, this is placed in and out of the accumulator under the condition of Yang H. Constructing a new, immediate and efficient Tai Li _ high-power tracking method designed - ^ 孓 coordinated solar installation system. 200827974 [Description of the Invention] The main purpose of this April is to propose a new type of solar power system maximum power chasing method and apparatus. The "Peter's Field Maximum Power Tracking Method" can be used in all solar systems. The method is mainly to add a kind of instantaneous power type supercapacitor to dynamically balance, by changing the duty cycle of the DC/DC converter (single value, and observing the super power 'voltage change situation') The duty ratio of the secondary DC/DC converter (DG/DC) converter adjusts the direction of the D value. It only needs to monitor the voltage value of the super capacitor. It does not need to detect the current 'true calculation of the solar power's wheel power. Backtracking mainly includes: As for the power tracking system of the solar system of the present invention, a solar panel: a momentary power type supercapacitor: an energy storage device that is directly connected to the energy balance, receives the energy output of the solar panel and outputs the flow/ DC/DC converter; DC/DC converter: Adjustable solar system output voltage and energy; Pulse width modulation driver: Transmit pulse signal to control DC/DC conversion [Embodiment] - The contents, features, and embodiments of the present invention will be described below in order to provide a further understanding of the present invention by the members of the present invention. 9, 200827974 In general, the maximum power tracking method of solar energy is required to calculate the P value of the output of the solar panel. When the power is not maximum, _rectifier/direct converter = duty cycle. Change the load load to make the solar panel output occur. Change. Again; 瞀 solar panel's turn-off power P, compare the two power changes, adjust the DC/DC converter's duty cycle, repeat the program, and oscillate to obtain the maximum power. The main program is as shown in the fifth. The p-value, such as Wei's electrical current, must have its current and current value, and the enthalpy is calculated by the multiplier. XV, I is the current and V is the voltage. Please refer to the fourth to sixth figures, the present invention does not need To measure the current value, it is only necessary to detect the V-value of the electric castle. The method of the present invention mainly uses an instantaneous power type supercapacitor (positioned between the solar panel (6) and the DC/DC converter (8) as energy ( The temporary storage container of electric energy, the electric energy is generated by the solar panel (6), enters the instant supercapacitor, (7), and then outputs the DC/DC converter (8). The input and output electric energy is in a steady state (visual state) visible instantaneous power type super capacitor (7) The net energy is zero, that is, no electric energy is accumulated in the supercapacitor, and the solar panel (6, (8) exhibits a dynamic balance. Too% can be 罝 (electric energy) W = pxt, and p: power ΐ · day守间··. W = IX ν X t removal time due to symplectic, then W = P = I XV, / Chuan f, curry nd discussion, t = Isec at any time, the energy flowing into the instantaneous power type super power = outflow The instantaneous power type half-recognition, and the energy of one (6) r β ^ ^ λ θ-0 (7), that is, the solar lunar slab (6) / melon into the instantaneous power type super, and the sub-private ( 7) The energy should be instantaneous 200827974 Transforming supercapacitor (7) The energy of the DC/DC converter (8) + The energy generated by the solar moon b plate (6) = The energy of the instantaneous power supercapacitor (7) = Outflow The energy of the instantaneous power type supercapacitor (7) = the energy of the human DC converter (8). | So, in the past, the power generated by the sun at the most arbitrarily light side of the sun was also disturbed, and the energy or power of the instantaneous power type supercapacitor (7) can now also be used. The energy of the instantaneous power type supercapacitor (7) is related to its quantity: w' W = 1/2 CX V2 W: the energy of the instantaneous power type supercapacitor (7), c: the capacity of the power type super container (7), V is The voltage of the instantaneous power type supercapacitor (7), since the capacitance C value of the instantaneous power type supercapacitor (7) is New, the energy of the instantaneous power type supercapacitor (7) can be expressed by the voltage of the instantaneous power type super capacitor (7), as long as there is The instantaneous power type supercapacitor (7) can be known from the voltage of the instantaneous power type supercapacitor (7), and the power generated by the solar panel can also be known. Therefore, this method only detects the instantaneous power type super thunder & Bao Gu is the simple and effective voltage of (7). The flow chart of its operation is shown in Figure 5. First of all:

When the vc value is greater than the set value, the maximum power system is started. Change the DC/DC converter (8) duty cycle D value and measure the new Vc value. If the new Vc value is greater than the original Vc ', the dc/dc converter (8) 11 200827974 duty cycle D value will be adjusted. If the new v value is greater than the original Vc, the DC/DC converter (8) duty cycle D value γ will be adjusted to change direction. E. Set the new vc value to Vc F and repeat the above steps again. After obtaining the maximum power of the solar panel (6) with the present invention, the logic control circuit (Work A) determines the charging mode according to the voltage condition of the battery. The current and voltage are adjusted to the battery (i 1) via the DC/DC converter (8). The system is charged in the pulsed charging mode when the voltage of the pool (1 1 ) is low, and is charged to the set voltage or higher. The energy generated by the solar panel (6) in the current state is fully charged to the battery (1丄), and reaches the late charging stage. The battery is fully charged in a pulsed charging mode (丄1), which has the characteristics of efficiency, fastness and low energy loss by the two-stage charging method. As for the invention adopting the smart adjustable mode, the solar system discharge 疋 in the present invention can be adjusted by the logic/control circuit (i 〇A) to determine the discharge mode, and the current/current conversion H(8)(4) determines the dissipative current or other manner of discharge. The DC/DC converter (8) converts the output of the battery. The load of this system (1 〇 ) can be LED light P train, Lamp, mechanical device, monitoring equipment, detection instrument and signal communication device. The load (1 〇 ), if it is an LED light array, needs to be fixed with the brightness of the new system. The solar energy is mostly 12V linonic acid battery. When it is fully charged, it can reach 16V, and the range of use is mostly between 13. 8~1 π. When the LED is driven by the reservoir (1 1 ), the led drive power/melon and the interaction will be caused by the voltage change of the lead-acid battery, so the brightness of the UD lamp will gradually become darker. The intelligent adjustable constant current system can keep the brightness of the LED street lamp constant. With constant current control, the serial current through the led 12 200827974 does not darken the street light. For some loads (丨Q), it is necessary to set the voltage, such as the wire setting, monitoring equipment, and detection instruments. A constant voltage is required to stabilize the machine. Through this system, the voltage discharge control can be more efficient, and even increase the output voltage to the load (1 0) and (4). The system of the present invention is simple yet integrated to achieve the best and too clever control mechanism with minimal parts.
