Abstract

The invention relates to the technical field of wind power generation, and discloses a crosswind yaw electrical control system and method for a wind generating set and the wind generating set, the system comprises a rotating speed acquisition module, a pressure acquisition module, a master control module, a mode control module, a hydraulic pump control module and a yaw motor control module; the master control module is respectively connected with the rotating speed acquisition module, the pressure acquisition module, the mode control module, the hydraulic pump control module and the yaw motor control module, the mode control module is connected with the hydraulic pump control module and the yaw motor control module, the hydraulic pump control module is connected with a hydraulic pump, and the yaw motor control module is connected with a yaw motor. According to the yaw control system, under the conditions that a sudden stop fault is triggered by overspeed of a unit and a safety chain is disconnected, the yaw electrical loop is triggered to be conducted by outputting a common DO, and then the yaw motor can receive a control instruction of the master control module to perform crosswind yaw action, so that the rotating speed of a fan is effectively reduced, and it is guaranteed that the rotating speed of the unit is within a safety range.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a crosswind yaw electrical control system and method of a wind power generating set and a generating set. Background technique [0002] The yaw system of the wind turbine can also be called the wind system. Since the wind direction changes frequently, if the swept surface of the blades of the wind turbine is not perpendicular to the wind direction, the power output will be reduced. The function of the yaw system is to track the change of wind direction, drive the nacelle to rotate around the centerline of the tower, and try to obtain the maximum wind energy. [0003] However, if the wind is too strong, it may cause the unit to overspeed. When the unit overspeed occurs, an emergency stop will be triggered, and the unit will disconnect the safety chain. At this time, the yaw DO has no output, and the unit cannot perform crosswind yaw. In this case, if the sweeping s...
