Abstract: In view of the problems of direct start yaw, soft start yaw and multi-frequency converter yaw, this paper proposes a multi-drive frequency converter yaw control scheme, and discusses the key technology of multi-motor drive control. The system can effectively solve the problems of soft shock and load balancing control of yaw system, which is helpful to improve the stability of yaw system. At the same time, it is conducive to promoting the technical progress of wind turbine yaw system to the direction of intelligence and digitalization, and can provide technical basis and scheme reference for yaw system fault diagnosis and early warning.
