The operation data acquisition and storage subsystem can transmit the operation data of each wind power plant device to a big data center or a cloud platform system in real time, all operation historical data are stored completely, and the data can be used for real-time data interaction and data analysis and provide basis for decision making of other subsystems.
(2) And the production scheduling subsystem is used for receiving the scheduling command sent by the power grid and decomposing the scheduling command into a scheduling decomposition instruction of each wind power plant and an auxiliary execution instruction of the other subsystems.
The production scheduling subsystem provides an interface with power grid scheduling, can receive scheduling commands issued by a power grid, operates and plans the decomposition of the scheduling commands in the province and assists in executing the scheduling commands, and feeds scheduling results back to the power grid in real time, and the scheduling command subsystem simultaneously serves as operation management work in the province.
Specifically, the production scheduling subsystem is used for decomposing the scheduling command by combining the scheduling command, the health condition diagnosis result of the wind turbine equipment of each wind power plant and the information of the spare parts in each spare warehouse in the provincial region.
