The Research Of The ECS Rebuilding Of Native 300MW Unit

This paper researched the principium, characteristic, design and some otheraspects of the Electrical control system (ECS) of generating unit. In rebuilding work oftwo 300MW unit of WeiFang power plant, the writer developed and debugged ECS ofthe two units, overcame a lot of problem, accumulated a large amount of relatedexperience. The rebuilding work proved successful: the automatic control level wasgreatly improved ,control of turbine,boiler and generator was perfectly combined to awhole. In actual unit ECS rebuilding process, the writer consummated research contentfurther, analyzed all kinds of the prevent problem of ECS rebuilding of native 300MWunits, mainly researched and improved the principle and realizing manner of automaticsynchronizing of unit. Based on the above, the writer prospected the developing trend ofECS.
