Abstract
The utility model discloses a photovoltaic power plant reactive compensation optimizing system, including measurement cabinet, photovoltaic mutual -inductor, reactive compensation controller and the inlet wire mutual -inductor of being incorporated into the power networks, measurement cabinet and external photovoltaic power generation component electrical property intercommunication are incorporated into the power networks, the photovoltaic mutual -inductor is installed the terminal outgoing lines of measurement cabinet of being incorporated into the power networks go up and with the binding post electrical property intercommunication of reactive compensation controller, the binding post and the inlet wire mutual -inductor electrical property intercommunication of reactive compensation controller, inlet wire mutual -inductor and commercial power electric wire netting electrical property intercommunication, the photovoltaic mutual -inductor is with the model specification with the inlet wire mutual -inductor, through increasing a photovoltaic mutual -inductor with the model specification, two power supply system data can be discerned simultaneously to the reactive compensation controller, and two systems can compatiblely use, and it is more convenient to use, and the solar energy transformation utilization ratio is higher, have saved the commercial power and have used and use cost.
Description
Technical field
This utility model belongs to field of power, particularly to the reactive power compensation ability system of a kind of solar photovoltaic power plant.
Background technology
Solar energy power generating has become as a kind of clean energy resource and is widely used, need to build corresponding photovoltaic plant, and roof pv grid-connected plant is usually after building completion and carries out design and construction, this is easy for there is photovoltaic plant and builds the situation that in original distribution design, reactive-load compensation equipment is incompatible, idle compensating control is caused normally to work, and then emergent power factor declines, the situations such as reactive power is excessive, particularly photovoltaic plant is after grid-connected putting into operation, if generated output take electric loading electric power ratio more than half, the most traditional idle compensating control cannot be normally carried out work, reactive compensation capacitor is cut out, two electric power systems can not compatible use, use to us and bring very big inconvenience, solar electrical energy generation can not effective trans-utilization, trans-utilization rate is low, virtually too increase use cost.
The photovoltaic plant reactive power compensation ability system that the technical problems to be solved in the utility model is to provide a kind of makes two electric power system compatibilities, idle compensating control normally to use, easy to use, solar energy trans-utilization rate high, use cost is low.
Utility model content
For solving that two electric power systems of above-mentioned prior art are incompatible, idle compensating control cisco unity malfunction in-convenience in use, the problem such as solar energy trans-utilization rate is low, use cost is high, this utility model adopts the following technical scheme that
This utility model provides a kind of photovoltaic plant reactive power compensation ability system, including grid-connected metering cabinet, photovoltaic transformer, idle compensating control and inlet wire transformer, described grid-connected metering cabinet and external photovoltaic electrification component electrical communication, described photovoltaic transformer be arranged on the outlet terminal of described grid-connected metering cabinet and with the binding post electrical communication of described idle compensating control, the binding post of described idle compensating control and inlet wire transformer electrical communication, described inlet wire transformer and utility grid electrical communication, described photovoltaic transformer and inlet wire transformer are same model specifications.
The beneficial effects of the utility model are: by increasing the photovoltaic transformer of a same model specification, idle compensating control can identify two electric power system data, two compatible uses of system simultaneously, uses convenient, solar energy trans-utilization rate is higher, saves civil power and uses and use cost.
Accompanying drawing explanation
Fig. 1 is the frame structure schematic diagram of a kind of embodiment of this utility model.
Detailed description of the invention
Describe preferred embodiment of the present utility model below in conjunction with the accompanying drawings in detail.
nullRefer to Fig. 1，A kind of photovoltaic plant reactive power compensation ability system，Including grid-connected metering cabinet 1、Photovoltaic transformer 2、Idle compensating control 3 and inlet wire transformer 4，Described grid-connected metering cabinet 1 and external photovoltaic electrification component electrical communication，Described photovoltaic transformer 2 be arranged on the outlet terminal 11 of described grid-connected metering cabinet 1 and with binding post 31 electrical communication of described idle compensating control 3，Binding post 31 and inlet wire transformer 4 electrical communication of described idle compensating control 3，Described inlet wire transformer 4 and utility grid electrical communication，Described photovoltaic transformer 2 is same model specification with inlet wire transformer 4，By increasing the photovoltaic transformer of a same model specification，Idle compensating control can identify two electric power system data simultaneously，Two compatible uses of system，Use convenient，Solar energy trans-utilization rate is higher，Save civil power to use and use cost.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitably change that it is done by any person of an ordinary skill in the technical field or modify, all should be regarded as without departing from patent category of the present utility model.
