针对风力发电变桨系统的实际需求，提出了一种新的降压启动伺服电机的策略。通过与分级启动、全压启动的仿真结果对比，该降压启动的方法能将启动电枢电流控制在允许的过载电流范围内，又能提供大的转矩实现快速变桨，满足快速动态响应的需求。

In light of the actual demand of wind turbine pitch system ,we propose a new low voltage starting strategy for servo motor . Simulation results show ,compared with the cascade starting and full voltage starting ,this method is able to make the armature cur‐rent within the permissible overload current range ,but also provide large torque for fast pitch ,to meet the needs of fast dynamic re‐sponse .
