Embodiment Construction
[0122] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0123] The embodiment of the present invention provides a wind farm control method, the specific flow chart is as follows figure 1 As shown, the specific process is as follows:
[0124] S101: The interval layer obtains the operation information of the wind farm and the wind farm control command of the station control layer;
[0125] S102: Generate a wind turbine control command based on the operation information and the wind farm control command;
[0126] S103: Control the wind turbine through the ground layer based on the control command of the wind turbine.
[0127] The above wind farm control commands are active power control commands, reactive power control commands or voltage control commands.
[0128] In S102, the wind turbine control command is generated based on the operation information and the active power control command, that is, the frequency ...

The invention provides a wind power plant control method and device. The method is characterized by, through a spacer layer, obtaining operation information of a wind power plant and a wind power plant control instruction of a station control layer; then, generating a wind turbine generator set control instruction based on the operation information and the wind power plant control instruction; andfinally, controlling a wind turbine generator set through a field interval layer based on the wind turbine generator set control instruction. The method and device realize centralized control of thewind power plant, give consideration to wind power plant grid access control for coordinated and cooperated operation between the wind power plant and a power grid control layer, greatly reduce difficulty of automatic control of the wind power plant, improve management and operation level of the wind power plant, and correct the active power reference value of the wind power plant obtained after the wind power plant participates in grid frequency control according to limit of a maximum active power value of the wind power plant and a minimum active power value of the wind power plant, therebyimproving accuracy of frequency control.
Description
technical field [0001] The invention relates to the field of new energy power generation scheduling automation, in particular to a wind farm control method and device. Background technique [0002] At present, the control of wind farms includes active power control and reactive power voltage control. Active power control is realized through active power automatic control. Active power output is adjusted to keep the total active power of the wind farm at or close to the active power control command value. The reactive power and voltage control is realized through the automatic reactive power and voltage control system. The automatic reactive power and voltage control system takes the grid-connected point voltage or reactive power as the control target, automatically receives the voltage / reactive power target command issued by the dispatching master station, and calculates the reactive power deviation or The amount of reactive power adjustment is to adjust the controllable re...
