Development of the Primary Restorative Transmission System Analyser to Restore Massive Blackout

광역정전 복구를 위한 시송전 계통 분석시스템 개발

Service restoration following a complete or partial collapse starts with reenergizing a transmission line from black-start generators. Voltage problems can arise from Ferranti effect as unloaded transmission line is reenergized. This Paper presents system analyser to develop for verifying the primary restorative transmission system. The algorithm which has been used in the analyser is to handle load pick-up compensating Ferranti effect. and terminal voltage and reactive capability limitation of black-start generators about self-excitation.
