The invention provides a short-circuit torque analysis and optimization method for a medium-speed permanent magnet synchronous wind driven generator, and the method comprises the steps: obtaining a simulation result through employing similar dual-winding and single-winding simulation, and comparing the simulation result with a preset threshold value, thereby achieving the short-circuit torque analysis and optimization of the medium-speed permanent magnet synchronous wind driven generator. According to the method, the initial electromagnetic scheme of the generator and the initial scheme of the semi-integrated transmission chain containing the gear box are adjusted and optimized to judge the feasibility of the initial electromagnetic scheme of the generator and the initial scheme of the semi-integrated transmission chain containing the gear box, and the feasible initial electromagnetic scheme of the generator and the feasible initial scheme of the semi-integrated transmission chain containing the gear box can
