Utility model content
Technical problem to be solved in the utility model is to provide a kind of device utilizing energy storage to improve thermal power plant AGC response, to improve thermal power plant AGC response speed, improves the economy of unit simultaneously and reduces the maintenance cost of relevant device.
The technical solution of the utility model is:
A kind of device utilizing energy storage to improve thermal power plant AGC response, including high voltage bus, switch, main transformer, electromotor, station-service Working transformer, 10KV auxiliary bus bar section, energy storage supply transformer and energy storage device and two-way inverter.High voltage bus connects main transformer, main transformer sending and receiving motor and station-service Working transformer by switch, and station-service Working transformer connects 10KV auxiliary bus bar section, and 10KV auxiliary bus bar section connects energy storage device and two-way inverter by energy storage supply transformer.
The beneficial effects of the utility model: utilize the technical solution of the utility model, when unit receives AGC liter or load down instruction, energy exchange is carried out by two-way inverter between unit station-service working bus bar and energy storage device, thermal power plant AGC response speed can be improved, improve the economy of unit simultaneously and reduce the maintenance cost of relevant device.
Accompanying drawing explanation
Fig. 1 is the composition schematic diagram of this utility model control system.
In Fig. 1,1-high voltage bus, 2-switchs, 3-main transformer, 4-electromotor, 5-station-service Working transformer, 6-10KV auxiliary bus bar section, 7-energy storage supply transformer, 8-energy storage device and two-way inverter.
Detailed description of the invention
Embodiment carries out thermal power plant AGC response by following steps and controls:
Step 1 builds control system:
As it is shown in figure 1, control system includes high voltage bus 1, switch 2, main transformer 3, electromotor 4, station-service Working transformer 5,10KV auxiliary bus bar section 6, energy storage supply transformer 7 and energy storage device and two-way inverter 8.High voltage bus 1 connects main transformer 3, main transformer 3 sending and receiving motor 4 and station-service Working transformer 5 by switch 2, and station-service Working transformer 5 connects 10KV auxiliary bus bar section 6, and 10KV auxiliary bus bar section 6 connects energy storage device and two-way inverter 8 by energy storage supply transformer 7.
The response that AGC load up is instructed by step 2 control system:
When unit receives the instruction of AGC load up, cut energy storage device and two-way inverter 8 and power to 10KV auxiliary bus bar section 6 to inverter mode, stop energy storage device when the power of the assembling unit reaches AGC demand and two-way inverter 8 works.
The response that AGC load down is instructed by step 3 control system:
When unit receives the instruction of AGC load down, cut energy storage device and two-way inverter 8 charges to energy storage device to rectification state, stop energy storage device when the power of the assembling unit reaches AGC demand and two-way inverter 8 works.
The above embodiment is only preferred embodiment of the present utility model, and the not feasible enforcement of this utility model is exhaustive.For persons skilled in the art, any obvious change done to it on the premise of without departing substantially from this utility model principle and spirit, within all should being contemplated as falling with claims of the present utility model.
