Abstract: Steam turbine is the main prime mover driving centrifugal compressor, and its reliability is very important for long cycle operation of the device. This paper analyzes the failure case of the oil circuit control system of steam turbine and the optimization is carried out from the aspects of design, operation and maintenance. The scheme has been applied in the existing units and new units, and the reliability of the units has been improved greatly.
