Abstract

Abstract: With the rapid growth of loads and external electric power infeed, the voltage stability in the load centers of the Pearl River Delta of Guangdong power grid is becoming increasingly prominent. In this paper, the voltage stability in the load centers of Guangdong power grid is investigated from the aspects of both the static and transient voltage stabilities and it is concluded that the 220-kV substations are prone to voltage instability. Therefore, the preliminary SVC application scheme is proposed in combination with the practical construction conditions of these substations and the availability of the scheme is verified from the aspects of both the static and transient stabilities. The result shows that the proposed scheme can enhance the voltage support in the load centers of Guangdong power grid and benefit the transient voltage stability of the system significantly.

Key words: SVC, Guangdong power grid, load center, voltage stability, dynamic VAR planning
