A logic optimization for power control of control system of M701D gas turbine

Abstract

Abstract:

Abstract:Based on the fact that a trip failure occurred to a M701D gas turbine,this paper concludes that the cause of this failure is because the potential transformer is inconsistent with original design on the actual wiring and the logic of power control of turbine control system (TCS) is unreasonable.To overcome this problem,this paper suggests to take action by reconnecting,adding power controller and optimizing logic of TCS.After these modification,under the circumstances that each power transmitter and TCS are consistent on channel and adopted value,and one or three phase of fuse of power transmitter is fusing,the result showed that the logic of TCS is calculated correctly,which effectively improved circuit fault of control system.
