Abstract

Currently, the increasing scale wind power paralleling in grid leads the range and frequent degree of thermal power unit regulating system action become larger than ever. So both the units' regulation performance requirements become higher and units' regulation system equipment performance faces more severe test. It's found that not only HP-valve's poor flow characteristics of software failure, but its loose connection parts of hardware failure can also cause unit load oscillation on based of studying two actual unit cases. Then, a method for fault identification with online monitoring are shown. Finally, the common optimization for two kind HP-valves' fault is carried out with great engineering application value to guarantee units operation with safety and efficient.
