ABSTRACT

The aim of this paper is to analyze static voltage stability of Vietnam power network at the level of 500 kV with the connection of the nuclear power plant and apply STATCOMs to improve the voltage stability of the system. Power system simulator for engineer (PSS/E), which is a powerful software for power system transmission analysis and generation performance in steady state and dynamics conditions, is employed for implementing and analyzing static voltage stability in this paper. To put it another way, P-V and Q-V analysis are carried out to assess both voltage stability and transfer capability of the power network corresponding to the normal operation mode and contingency modes. The purpose of the analysis is to define the unstable voltage buses and contingencies that potentially affect the voltage stability. Moreover, STATCOMs application to enhance voltage stability, power transfer as well as voltage quality of the Vietnam’s power system is carried out.
