For overcoming above shortcoming, the solar energy transformer station electric power system that the utility model proposed is installed solar panel according to transformer station's existing equipment at transformer station's roof, and is electrically connected with the transformer station direct current system storage battery, to charge in batteries.
The technical scheme that the utility model is taked is:
A kind of energy-conservation intelligent substation electric power system of utilizing solar energy; Comprise alternating current is converted into galvanic rectification module; The output of said rectification module is connected with the dc feeder bus that is used for the substation equipment power supply; Also be connected with insulator detecting unit, switching value detecting unit and data monitoring unit on the said dc feeder bus; Wherein the test side of insulator detecting unit and switching value detecting unit is connected with the power consumption equipment of transformer station and obtains the operating state signal of substation equipment, and output is connected with the signal receiving end of data monitoring unit, and the output of said data monitoring unit is connected with data transmission unit; Said electric power system also comprises and is located at the solar panel that can fully receive the position of solar irradiation; Said too can tabula rasa via controller unit with unit, anti-reverse charge road after be connected with batteries, said batteries has battery management unit and is connected with the dc feeder bus of transformer station.
As a kind of improvement of above technical scheme, said data transmission unit is connected through the data receiving terminal of network with the central machine room that is arranged on power supply department.
The beneficial effect of the utility model is:
The solar energy intelligent substation electric power system that the utility model proposed is made optimization to the application of transformer station to heliotechnics specially; It installs solar panel according to transformer station's existing equipment at transformer station's roof, and is electrically connected with the transformer station direct current system storage battery; To charge in batteries; And through the intelligence utilization of controller unit realization to solar energy, the equipment investment maintenance cost is lower, and the not wiring wiring of complicated transformer station.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the principle schematic of the utility model.
Embodiment
As shown in Figure 1; The intelligent power supply system that is used for solar energy transformer station disclosed in the utility model comprises that the 380V alternating current with input transformer station is converted into galvanic rectification module 1, and its output is connected with the dc feeder bus 2 of transformer station being the power devices of transformer station under regular situation.
Also be connected with insulator detecting unit 3, switching value detecting unit 4 and the data monitoring unit 5 of the state that is used to monitor the substation equipment operation on the dc feeder bus 2; The test side of insulator detecting unit 3 and switching value detecting unit 4 is connected with the power consumption equipment of transformer station and obtains detection signal in this embodiment, and output is connected with the signal receiving end of data monitoring unit 5 so that the transfer of data of collecting is stored in data monitoring unit 5.In addition, the output of data monitoring unit 5 is connected with data transmission unit 6, data are sent in real time or by preset time the data receiver of the central machine room that is positioned at power supply department through network.Said network can be the Internet, wireless or wire communication network or dedicated network.
Electric power system proposed by the invention also comprises the solar panel 7 that is located at the position that can fully receive solar irradiation (such as the roof that is arranged on transformer station towards shining upon direction); Solar panel 7 via controller unit 8 are connected with batteries 10 with 9 backs, unit, anti-reverse charge road, and batteries 10 has battery management unit 11 and is connected with the dc feeder bus 2 of transformer station.Like this, solar panel 7 is an electric energy with conversion of solar energy, and under the control of controller unit 8, directly power supply perhaps charges a battery to substation equipment, reduces the demand of transformer station to the 380V alternating current of input, and then realizes the purpose of environmental protection and energy saving.The charge protection that controller unit 8 wherein also is used for Based Intelligent Control whole system operation state and combines anti-unit, reverse charge road 9 and battery management unit 11 to realize batteries; Rationally arrange the impulse electricity of batteries; Anti-recoil and overshoot prolongs the life of storage battery.
Therefore; The utility model is introduced solar energy in the power supply of transformer station with equipment; Reduced the loss of transformer station to transferring electric power effectively, even full station loses the station with power supply, sun-generated electric power still can be supplied power for transformer station through its batteries; To power equipment operation, operation, maintenance electric energy is provided, has guaranteed the stable operation of transformer station.
The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection range, so long as realize that with essentially identical means the purpose of the utility model all should belong to the protection range of the utility model.
