As part of the high-speed shaft coupling, the torque limiter used by the wind turbine generator is installed near the generator side. It has the function of overload protection, which can effectively cut off the great torque generated when the low voltage ride through and the motor are short-circuited, and reduce the damage to the transmission system. In actual operation, especially when running at full power, the torque limiter will often slip, which will increase the damage to the transmission system and reduce the power generation efficiency. This paper analysis the principle of vector control on the machine side of the unit, and finds the cause of the slip of the torque limiter and the solution.
