摘要
Abstract
A runback test of unit is conducted in Shanwei power plant, and the test result is analyzed. Focusing on the faults in the test, such as fan vibration due to coal grinder trip, rapid open of main steam valve due to high pressure slipping rate of the set value of main steam pressure,and fast rise of water level in No. 3 high-pressure heater,modifications of the fan control logic and the pressure slip-ping rate of the set value of main steam pressure are performed, and the urgent drain valve is pre-opened to a certain extent. Satisfactory control result is achieved via these measures.关键词
