利用WDPF DEH-MOD Ⅲ修改汽轮机保护逻辑的工程实践

Project Practice of Modifying Protection Logic of Steam Turbines Using WDPF DEH MOD Ⅲ

分析利用ＷＤＰＦＤＥＨＭＯＤⅢ闲置资源设计汽轮机保护逻辑的可靠性、安全性及可行性，介绍该方案在上海外高桥发电厂３００ＭＷ机组的工程实践过程及效果，提出在已投入商业运行的发电机组中，利用现代计算机控制技术修改和实现汽轮机保护逻辑是一个安全可靠、快速经济的方法。

The reliability,safety and feasibility of designing protection logic of steam turbines using the idle resources of WDPF DEH MOD Ⅲ are analyzed;and the project practice process and effect of the scheme on 300 MW generating units in Shanghai Waigaoqiao Power Plant are introduced.It is suggested that,on the generating units put into commercial operation,to apply modern computer control technology to modify and realize protection logic of steam turbines is a safe and reliable,fast and economical method.
