A Study on Voltage Stability Assessment Using the Reactive Reserve Iindex

  • 발행 : 2007.07.18

초록

The reactive reserves of generators is close to voltage stability. This characteristic has led to the development of a few year monitoring the reactive reserves. In this paper, the reactive reserves have been calculated considering the generator capability curve. In addition, through dividing the systems using electric distance, the reactive reserves of each area has been calculated. Then, using the correlative relationship between reactive reserves and PV margins, the method for monitoring the voltage stability is proposed. The proposed method is tested on PSS/E test system and KEPCO system.
