When the Over Speed Control (OPC) acts very often, the pressure switches of safety fuel will be released, which maybe lead to the turbine tripped. Some steam leak out from the governor valve flange face. The work temperature of LVDT is very high. The coils of LVDT are sometimes short out. The actuator isout of control inducing the turbine tripped. The improvement suggestions are proposed in this paper.
