Research On Monitoring Mode Of Station Service System In Large Power Plant

Comparing with that power plant distributed control system(DCS) emphasizes on monitoring thermal system,electrical control system(ECS) places emphasis on monitoring power plant electrical system.In order to coordinate the synchronous development of thermal control and electrical automation in power plant,improve the automation level and control management level of power plant,guarantee the security and reliability of power plant operation,and enhance the advantages and competitive ability of power plant in current economical operation of power market,the study on monitoring modes of plant power supply in large power plants has very important_meaning.Based on existing rules and regulations,design experiences and developing trend of plant power supply monitoring system,combined with advanced domestic and foreign technology,the thesis studies on monitoring modes of plant power supply in newly-built 2×600MW generating unit,gives detailed discussion and comparison of various monitoring modes,proposes technical and economical comparison and investment difference of various modes,and describes application modes of field bus technology in plant power supply monitoring system.It provides scientific and reasonable design schemes for optimizing plant power supply monitoring system and saving project investment of newly-built 2×600MW generating unit.
