The phenomenon of lock；Its concrete condition is as follows：
If it is determined that the time interval of the last yaw end of distance is in preset time during yaw, then to continuous yaw
Interval preset time indegree is added up, and minimum 0, largest cumulative 6；After this time yawing, next time yaws earliest
Time interval depends in the preset time of yaw interval the time interval of corresponding yaw next time of number added up, if certain is sentenced
The time interval that the last yaw of distance terminates during disconnected yaw is greater than or equal to preset time, then when default to accumulative yaw interval
Interior number is zeroed out；
The earliest time of next yaw maneuver is so adjusted according to the frequency that is yawed in setting time of yaw, to control
Yaw air switch thermal element will not within the time of concentration persistent accumulation heat, have sufficient time to adjust release accumulation
Heat, so as to ensure that air switch is operated in kilter.
Compared with prior art, the present invention having the following advantages that and beneficial effect：
1st, the present invention, by varying Yaw Control Strategy, it is inclined to solve wind power generating set in the case where being changed without hardware
The problem of avionics machine air switch tripping, saves unnecessary cost and labour cost, has retrieved because yaw motor is empty
Air cock trips, wind power generating set unnecessary economic loss caused by forced-stopping machine.
2nd, by adjusting the time interval after yaw every time according to yaw frequency in control strategy, control yaw motor is reached
The heat of air switch thermal element will not persistent accumulation and maintains normal condition；By each according to blast velocity control in control strategy
