Abstract
Single valve and sequence valve can not be normally switched due to control instruction fluctuation of medium-pressure regulating valve of steam turbine after integration of 660 MW units. The paper analyzes control mechanism of medium-pressure regulating valve of steam turbine DEH (digital electro-hydraulic control system) and expounds problems of major parameter control during generating units startup by comparing the examples. The method of eliminating control instruction fluctuation of medium-pressure regulating valve through control modes switching can be reference for steam turbine turning and controlling in other power plants.关键词
