汽轮机DEH/MEH系统主站控制器全故障问题分析及对策

The Analysis and Countermeasures on DEH/MEH Systems Master Controller’s Faults of Turbines

随着分散式控制系统产品运用于电厂汽轮机控制系统，其控制系统的大脑（DPU）安全运行变得越来越重要。如果一旦DPU控制器全故障问题出现，控制系统应有相应的防范措施。本文针对DEH／MEH产品对控制器发生全故障问题后提出解决对策，试图提供有益借鉴，提高DEH／MEH应用水平．从而提高发电机组的安全性和可靠性。

With the usage of the distributed control system products in the turbine control system of power plant, the safe operation of the control system of the brain, i.e. DPU, becomes more and more important. If the DPU controller is in fault, the control system should have the appropriate preventive measures. This article puts forward some solutions for the main controller＇ s fault problems of DEH/MEH products, and tries to provide a useful reference, and raises the level to improve DEH/MEH in order to enhance the safety and reliability of generating units.
