摘要:

摘要:针对一起M701D型燃气轮机跳机事故,通过理论计算及分析,得出跳机原因为电压互感器(PT)实际接线与图纸不符、燃气轮机控制系统(TCS)功率控制逻辑混乱,采取了重新接线、增加功率控制器并优化TCS“三取中”控制逻辑的改进措施。改进后的实际应用表明,各功率变送器与TCS内对应通道及采用值一致,PT一相或三相熔丝熔断的情况下,TCS逻辑计算准确,有效提高了控制系统抗二次设备和回路故障的能力。

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.
