Abstract :
A 500 Hz power system is proposed for industrial zones, intelligent buildings, and commercial areas. An experimental system composed of two 10 kVA power converters, a power transmission line simulator, and voltage compensators shows high speed and good system voltage regulation by combining the reactive power control of the voltage compensators and DC link voltage control of the power converters. Reactive power control is also able to compensate for asymmetric voltage due to unbalanced loading or voltage drop of the transmission line. A naturally commutated thyristor inverter suitable for high-power applications and a forced commutated transistor inverter suitable for medium-power applications are examined. The control circuit is fully digitalized and simplified by using 8-bit one-chip microprocessors. Some typical faults on the transmission line are discussed, and the experimental results obtained by the simulator are presented.<>
