Abstract

The power transfer capability has been recently highlighted as a key issue in many utilities. The total transfer capability in the KEPCO power system is determined mainly by the voltage stability limit and an enormous number of contingencies should be analyzed to determine the total transfer capability. In this paper, a new ranking index for determining the total transfer capability from voltage stability point of view is presented. This index is applied to the practical system of KEPCO and the effects of ranking the contingencies are analyzed by use of PSS/E package and a developed IPLAN program.

송전용량산정은 최근에 많은 전력회사에서 중요한 문제로 부각되어 왔다. 한전 시스템의 경우 전체송전용량은 주로 전압 안정도에 의해 제한을 받고 있으며, 전체송전용량 산정을 위하여서는 수많은 상정사고들에 대해서 분석하여야 한다. 따라서 전체송전용량 결정을 위한 전압안정도 측면에서의 상정사고를 효과적으로 선정하는 기법이 절실히 요청되고 있으며, 본 논문에서는 전체송전용량 결정을 위한 전압안정도 측면에서의 상정사고를 효과적으로 선정하는 새로운 상정사고 선정지수를 제시한다. 그리고 이 전체송전용량 결정을 위한 전압안정도 측면에서의 상정사고 선정지수의 효율성을 검증하기 위해 이 지수를 한전의 실계통에 적용하고 PSS/E 패키지와 개발한 IPLAN 프로그램을 사용하여 이 지수의 상정사고 선정에 대한 효용성이 분석된다.
