Abstract

In this paper, we describe the effects on the power system by adding renewable generator. In order to examine the stability of the system, the system analysis was performed using the PSS/E software. We confirmed whether occur the line overload of system through the load flow analysis and contingency analysis. and confirmed whether exceed of fault current using the fault current analysis. Dynamic stability of the system is analyzed through dynamic simulation. The analysis of the system according to the addition of the renewable generator was carried out according to the power system reliability and electricity quality maintenance standard.

본 논문에서는 신재생 발전원의 추가에 따라 계통에 미치는 영향에 관하여 서술하였다. 계통의 안정도 검토를 위해, PSS/E S/W을 이용하여 계통 해석을 수행하였다. 정상상태 조류 계산을 통한 선로 과부하 검토 및 고장 용량 해석을 통한 고장 전류초과여부 및 상정고장 해석을 통한 선로 과부하 여부를 확인하였다. 다이나믹 시뮬레이션을 통해 계통의 동적안정도를 확인하였다. 신재생 발전기 추가에 따른 계통 해석은 전력계통 신뢰도 및 전기품질 유지기준에 따라 해석을 수행하였다.
