Abstract
Based on the analysis of the operation
switching and control of the series compensation device in a 500kV substation
the principles of the capacitor
MOV
triggering gap and damping reactor are comprehensively expounded.In this paper
the capacitor with external fuse and internal fuse
the corresponding advantages and disadvantages are studied emphatically.The protection measures to restrain the overvoltage occurred in the capacitor bank are suggested.The correct switching and control methods to the series compensation device are further determined.
