Study on the System Method of DCS Remote Operation and Maintenance System of Nuclear Power Plant Based on Parallel Theory

In view of the actual needs and problems in the actual maintenance of nuclear power plant DCS system, this paper analyzes the complexity of O&M work in DCS system, puts forward the basic concept, working framework of the parallel operation and maintenance (O&M) of nuclear power plant DCS system based on the parallel theory. By establishing an O&M system parallel to the original nuclear power DCS system, remote monitoring of group reactor DCS equipment status can be realized. The paper also introduces the technical paradigm, characteristics, challenges and the significance of parallel O&M system, and discusses the current situation and future development trend of DCS operation and maintenance of nuclear power plants.
