Abstract: The DEH control system was adopted for the turbine of a certain power generation corporation limited, the hydraulic prepressure part of the system is EH1000 containerization feed installment. After the system was put into operation, the EH oil temperature increased abnormally, and the EH oil quality was deteriorated gradually. The abnormal phenomenon was analyzed earnestly, and based on this, the relevant treatment measures were proposed. After the treatment measures had been adopted, the phenomenon of EH oil quality deterioration had been eliminated basically.
