Analysis and Measures of Transient Voltage Instability in Three Chinese Large Load Centers

摘要

In China, Beijing, Shanghai and Guangzhou (BSG) are the most developed city in Jingjintang, Yangtze River Delta and Pearl River Delta areas respectively, so these cities' power system security is very important. In the conditions of a great deal power imported from outside, the local systems should be able to receive and response correctly in emergency. But at current transient voltage instability threatens the power systems of load centers seriously. In this paper, some typical transient voltage incidents are analyzed, the possibility of voltage instability and corresponding measures in BSG systems are studied, and the future work is presented.
