ABSTRACT:
A supervisory control system for an electric power system comprises a synchronized encoder for producing digital signals from voltage and/or current data detected by at least one of a number of detecting devices for such data coupled to the power system at various points. Inherently stationary data detected by similar detecting devices are converted into digital signals by asynchronous encoders. Responsive to such digital signals, data processing means produces address signals representative of the addresses of the detecting devices and processes the digital signals in compliance with programs for various supervisory control and with reference to the address signals to produce control signals, which are sent to circuit breakers, voltage regulators, and the like to protect the power system against troubles.
