现代汽轮机控制系统的控制策略是在传统的基本控制策略的基础上,考虑了电网控制,热网控制和机炉协调控制的需要而发展起来的。数字电液控制系统DEH(Digital Electro-Hydraulic Control System)是现代汽轮机控制系统的典型形式。本文的要点在于基于传统汽轮机电调功能之上提出的系统改造方案,关键是液压系统的改造, 以实现纯电调全部控制功能。关键字:DCS, DEH, TSI,汽轮机Abstract: The modern steam turbine control system policy is consider electricity network control ,heat network control and machine furnace correspond control based on the traditional control politic. DEH is the model form of modern steam turbine control system . The article point is bring forward system alteration project based on tradition steam turbine DEH system and realize all DEH control function.Key words: DCS, DEH, TSI, Steam Turbine
