Abstract :
During the first year of operation, four cases of instability developed at Conowingo hydroelectric station of the Philadelphia Electric Company when faults occurred on the transmission lines. Subsequent investigations showed that some of the generators would advance 180 deg. ahead of the system in less than 0.3 sec. when full load was dropped suddenly. Installation of higher speed relays and circuit breakers together with changes in the operating set-up, have corrected the situation.
