西门子TXP系统逻辑块在超临界机组控制系统改造的应用经验

上海外高桥第二发电有限责任公司2×900 MW超临界进口燃煤发电机组,2017年和2018年分别对两台机组实施了控制系统一体化改造,DEH和MEH系统由原来德国西门子公司的TELEPERM-XP控制系统,改为EMERSON公司的Ovation系统。选取了西门子TXP系统几个重要的逻辑块,总结了改造过程中的难题破解过程及应对方案。

Shanghai Waigaoqiae NO.2 Power LLC. has 2×900MW supercritical imported coal-fired generating units,which implemented integrated control system transformation in year 2017and 2018.1n this project,DEH and MEH system from the original German SIEMENS＇s TELEPERM-XP control system,changed to EMERSON＇s Ovation system.This paper selects several important logic blocks of SIEMENS TXP system,sums up the process of solving problems in the process of transformation and the solution.
