Abstract: The particular case of the micro electro hydraulic control system (MEH) reformation of the boiler feed pump turbine and the fault of difficulty in latchon occurred in operation after the reformation were introduced. According to the experimental analysis, the reasons of the MEH system fault were found out, and the optimizing measures were given, the problems in MEH reformation were solved. 
