ПРИСТРІЙ РЕГУЛЮВАННЯ ЗБУДЖЕННЯ СИНХРОННОГО ДВИГУНА В УМОВАХ РІЗКОЗМІННОГО НАВАНТАЖЕННЯ

摘要

Excitation regulator of synchronous motor at quick-variation load consists of a synchronous motor with excitation winding, the unit for calculation of active and reactive components of the stator current. In parallel to excitation winding through the rotor current sensor and a buffer throttle transistor inverter is connected, to the output of which a storage capacitor is connected, the output of the excitation controller voltage generating unit is connected to the second input of the transistor and thyristor converter control unit with the first input connected to the output of the rotor current sensor, the first output of the transistor and a thyristor converter control unit is connected to the control input of the transistor converter, the second output of the transistor and thyristor converter control unit is connected to the control input of the thyristor converter, this through a step-down transformer is connected to the network.
