Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings.
[0015] refer to figure 1 and figure 2 , a dormancy control method for an AC pitch control system, the method comprising the following steps:
[0016] (1) Sleep mode entry logic: When the wind turbine is in the normal power generation state, the pitch control system drives the blades to reach the optimal pitch angle position, and the optimal pitch angle is 0°. And when︱the actual position of the blade︱optimum pitch angle︱≤0.1° error, the delay setting time is long for a period of time (for example, the delay parameter is 30s), then the main control control pitch control system enters the sleep mode, that is, the MPC The state machine enters the switchedOn state, the MPC stops outputting, and the pitch motor brake is applied, and the MPC is the driver of the pitch control system;
[0017] (2) Sleep mode exit logic: When MPC fails (BTB signal is 0) or ︱main control pi...
