Abstract: Abstract:In Harbin Third Power Plant of Huadian Energy Company Limited, after the distributed control system of the 600MW unit was put into operation, the system operation was unstable. So the unit stability lowered greatly, and the safe operation of the plant was affected. Combining with the actual situation of the unit operation, the occurred problems were analyzed one by one, and the solving scheme was proposed. After the scheme had been implemented, favorable results were obtained.
