Abstract: A method and an apparatus for controlling wind turbine power. The method includes: determining a compensation value for target active power based on a power difference between a net grid-connected power and the target active power; determining a setpoint value of active power based on the target active power and the compensation value; and performing a current-varying control and a pitch control based on the setpoint value of active power.

Abstract: The present disclosure provides a control method, device and system for a wind turbine. The control method includes: acquiring current working conditions of a power system, a yaw system and a communication system of the wind turbine when a typhoon warning signal is received; determining a target control strategy corresponding to the current working conditions according to a preset corresponding relationship between control strategies and working conditions of the power system, the yaw system and the communication system, wherein the control strategies may include an active windward strategy for controlling the yaw system to face typhoon wind direction, a controlled passive leeward strategy for controlling the yaw system to face opposite to the typhoon wind direction, and a passive leeward strategy for adjusting the yaw system to face opposite to the typhoon wind direction; and controlling the wind turbine by using the target control strategy.

Abstract: Provided are a method, a device, and system for controlling an operation of a generator, where the generator includes at least two power generation and transmission loops. The method includes: upon detecting the failure of any one of the at least two power generation and transmission loops, determining whether a preset condition for entering a partial power operation mode is satisfied; and when it is determined that the preset condition is satisfied, controlling at least one non-malfunctioning power generation and transmission loop of the at least two power generation and transmission loops to enter an operation mode, and controlling the malfunctioning power generation and transmission loop to enter a shutdown state, so that the generator enters the partial power operation mode.
