In this paper

problems in such fields as configuration of protection and control system of existed series compensation system

anti-interference of secondary system

hardware and software systems and operation logic are analyzed in detail with combination of study of operation and maintenance experience of series compensation protection and control system.The pertinence and practical precaution measures are proposed.The research result is helpful to operation

maintenance and management of existed series compensation protection and control system

plays an actively instructive role in the modification and optimization of the system

and is of important reference in the localization research of series compensation protection and control system.
