滑差就是发电机电压和系统电压频率的差(频差),发电机并网时,要求滑差应小于允许值。但是,如果滑差太小,发电机并网的时间会很长,此时可适当加速发电机,从而提高滑差。
主要类型可分为鼠笼式、绕线式及滑差电机拖动。
The main types of motor are squirrel -cage, winding and differential types.
维持滑差频率不变,就可获得近似于恒定转矩的输出特性。
Keeping slip frequency constant we can get nearly constant torque output characteristic.
所配发电机是一台高效率的4极双馈式发电机,带有绕组转子和滑差线圈。
The matched generator is a high efficient 4-pole double feeding generator with wound rotor and slip windings.
