REACTIVE-POWER COMPENSATOR FOR COMPENSATING A REACTIVE-CURRENT COMPONENT IN AN ALTERNATING-VOLTAGE SYSTEM

摘要

- 18 -AbstractIn a reactive-power compensator comprising areactive-current converter of forced-commutation currentconverter rectifiers (1, ..., 4) in a current converterbridge circuit and a smoothing choke (10) used as termina-tion at the direct-current side, the advantage of constantcompensation of both inductive and capacitive reactive-current components with clearly reduced system reactionis obtained by a special type of drive mode by means ofsinusoidal width-modulated control pulses.(Figure 1)
