Abstract

The system provides high speed coupling to two alternator sources to a load network so that phase angle, frequency and output levels are maintained at a predetermined acceptable level. The difference between voltage and frequency outputs is compared in the coupling system and also the relative phasing to preset constants. Phase measurements are made using a counting circuit giving difference in degrees and sign. The coupling includes the means to regulate the timing of the tripping in and out relative to the characteristics of the circuit breakers used. Operational amplifiers and a clock frequency generator working at a frequency much higher than that of the generators are employed in the comparison of frequency, phase and amplitude resulting in a frequency dependent control voltage.
