把感应电动机用作异步发电机以代替供应不足而价格昂贵的同步发电机,在苏联农村水电站中很早就被采用了。根据苏联经騐,一切感应电动机不需要經过任何改装,也不論它是用那一种原动机帶动,只要在它的靜子线端接上適当容量的靜电电容器(作为異步發电机的励磁用——通过静电电容器的电流就是異步發电机的励磁电流),就可只象同 The use of induction motors as asynchronous generators to replace under-supply, expensive synchronous generators was adopted very early in Soviet rural hydroelectric power plants. According to the experience of the Soviet Union, all induction motors do not need to undergo any modification, and no matter which type of prime mover they use, they must be connected to their stator wires with appropriate capacity electrostatic capacitors (used as excitation for asynchronous generators. - The current through the electrostatic capacitor is the excitation current of the asynchronous generator), just like the same
