Transient stability analysis of the Yongwol.Bupyong power system by electronic analog computer techniques

상이형전자계산기에 의한 영월.부평간 송전계통의 과도안전도 해석

Transient stability analysis of Yongwol-Bupyong power system, which contains Yongwol steam power station, the largest one in Korea, was undertaken by using the Yonsei 101 Analog computer. The critical switching time and phase angle for the present 150MW power flow to be stable were found. And the transient stability power limit for the system was also found. It is concluded that the system becoms unstable if the power flow increases much more than 151MW.
