| Notes | 23-1202/TH Wang Dajiang , Liang Haiping , Li Wenyun, Zhu Tao, Zhao Chuan, Gu Xueping （1. State Key Laboratory of Alternate Electrical Power System with Renewable Energy Sources, North China Electric Power University, Baoding 071003, Hebei , China. 2. Yunnan Power Dispatching Center, Kunming 650011, China） Power system restoration in a rapid and reliable way after blackout is an important measure to reduce loss. Extended black - start strategy is a novel way for power system restoration, but the network to be restored is more com- plex than that of black - start strategy in which one generator is started. The over - voltage problem of restoration path when the started units are charging is one of the important factors that affect successful unit start. To obtain the reason-able model of charging, the paper analyses the mechanism and characteristics of power frequency overvoltage and switching overvoltage. Then taken the extended black - start scheme of southern power system of Hebei province as an example, diffe |
