Abstract
This disclosure relates to a synchronous motor KVAR regulation system which utilizes a synchronous motor connected to a power distributor line to generate corrective (capacitive) KVARS to automatically follow and compensate for KVARS being generated by the other loads on the distribution line. The system takes into consideration the thermal capacity (motor rated current) of the synchronous motor so that the KVAR regulation system is not permitted to overexcite the synchronous motor for long periods of time. The KVAR regulation system also programs a minimum motor field current with respect to the motor load so as to insure that the synchronous motor will not pull out of synchronism during peak loads.
