우리나라 계통의 전압불안정 문제를 개선하기 위한 STATCOM과 SVC의 적용 검토

A Study on the Application of STATCOM, SVC to Enhance the Voltage Stability

Recent catastrophic failures of power system in various countries highlight the importance of the voltage stability and reactive power operation. Under the emergency situations, dynamic reactive power sources such as STATCOM and SVC play important roles in supporting the system voltage. This paper investigate the stability problem in KEPCO system and suggest the installation of the dynamic reactive Power sources as a countermeasure.
