| 摘 要： | ＤＥＨ系统中阀位传感器的故障会给阀门管理带来混乱，特别在调节级压力回路未投入的情况下会引起汽机功率的较大变化。本文基于解析冗余原理，提出用信号重构的方法来实现单个阀位传感器故障下的容错阀门管理。仿真结果表明此方法简单而有效。

| Abstract: | The failure of valve opening sensor would cause valve management of DEH system working confusedly,and result in large scale change of turbine power in the case of governing stage pressure loop idle. This paper presents the fault tolerant strategy of valve management under the failure of valve opening sensor via signal reconstruction. Simulation results indicates that the method is simple and effective. |
