According to the controlling requirement of megawatt wind driven generator with variable propellerpitch of horizon axis, the hydraulic control system of a variable propellerpitch is designed.
针对兆瓦级水平轴变桨距风力发电机的控制要求,设计了变桨距液压控制系统。

Load control is to regard the controllable pitchpropeller as the adjuster of load of a main engine.
负荷控制就是把调距桨作为主机负荷的调节器。

The system operates by a lever (28) which controls a pitchcontrol unit (10) which in turn controls engine speed and also the pitch of propeller blades (12) of propeller (14).
