Description
Technical field
The present invention relates to solar photovoltaic generation system technical field, particularly a kind of distributed generation system with security control in a kind of solar energy power generating.
Background technology
Solar photovoltaic generation system, as a kind of major way that utilizes solar energy, due to clean energy resource can be provided, reduce traditional fossil energy environment is damaged, and since entering the new century, in global major country, has obtained greatly developing.
Now electric power system is in the world to take the centralized single electric power system that large unit, large electrical network, high voltage be principal character, at society to the energy and supply of electric power quality and safety reliability requirement more and more higher in the situation that, the defect that large electrical network exists is more and more obvious, the disturbance that for example in centralized large electrical network, the fault of any point produces all can affect greatly whole electrical network, when serious, may cause large-area power-cuts or even Tie-line Opening, cause catastrophic effect; And this large electrical network is very easily subject to again the destruction of war or terrorist forces; Centralized large electrical network can't be followed the tracks of the variation of electric load in addition, and the cost of separately building power plant for of short duration peak load is huge, and economic benefit is also very low.Therefore, adopting distributed generation system is for improving the main method of security of system and flexibility in conjunction with bulk power system.
Distributed photovoltaic power generation refers to employing photovoltaic module, solar energy is directly converted to the distributed generation system of electric energy.It is a kind of novel, tool generating with broad prospects for development and comprehensive utilization of energy mode, it advocates generating nearby, grid-connected nearby, conversion nearby, the principle of using nearby, not only can effectively improve the energy output of same size photovoltaic plant, also efficiently solve the loss problem of electric power in boosting and transporting for long-distance simultaneously.A few days ago, Chinese Government has issued some supports and the subsidy policy about promoting that photovoltaic industry develops in a healthy way, and this will promote photovoltaic industry to comprise that distributed photovoltaic power generation system greatly develops.
Photovoltaic generation has the defect of himself, and its generating efficiency is subject to the impact of surrounding environment larger, such as the impact due to local shade may cause the high heat in part and then the initiation fire of photovoltaic module; In addition, because the price of assembly is higher and the impact for whole photovoltaic system for the integrality of each electrification component array, antitheft can be also the problem that needs of photovoltaic system are considered; Have again, when photovoltaic generating system goes wrong or during fault, finds timely and warn also particularly important.
Summary of the invention
In order to adapt to the needs of distributed generation system development and to avoid electricity generation system to occur above-mentioned problem, the object of the present invention is to provide a kind of distributed generation system with security control, it has antitheft, automatic protection and sends in time the functions such as warning.
To achieve the object of the present invention, the distributed generation system with security control of the present invention comprises the one or more solar cell power generation square formations that consist of solar module, the Intelligent wiring box being connected with battery component, the inverter being connected with solar cell power generation square formation, intelligent electric meter and supervisory control system, wherein, described Intelligent wiring box has electrical connection protector and sensing chip, and described sensing chip is connected with described supervisory control system; On described intelligent electric meter, there is a key X button.
Preferably, the electrical connection protector of described Intelligent wiring box consists of the bimetal leaf of different heat expansion coefficient, and when terminal box external temperature reaches a predetermined value, described electrical connection protector disconnects and makes cell panel stop external power output; When temperature reduces, described electrical connection protector conducting recovers externally output.
Preferred again, described intelligent electric meter end has detection module, and when assembly is stolen by people, described detection module gives a warning.
Preferred again, the sensing chip in described Intelligent wiring box detects the generating efficiency of solar module in real time, when generation is abnormal, immediately abnormal information is passed to described supervisory control system.
The distributed generation system described in of the present invention with security control is realized security monitoring and the protection of system by Intelligent wiring box and intelligent electric meter and supervisory control system, have that high temperature is protected automatically, antitheft and system immediately monitoring and alarm function.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, the present invention is aforesaid will be become apparent with other object, feature and advantage.Wherein:
Figure 1 shows that the structure composed schematic diagram of the distributed generation system with security control of one embodiment of the invention.
