根据独山子热电厂的实际情况，依据“在保护不发生拒动的基础上，尽可能减少误动”的原则，从防止抽汽倒流引起的汽轮机超速飞车事故出发，提出了相对完整的汽轮机热工保护的冗余改造技术方案。
According to the actual situation of Dushanzi Thermal Power Plant and based on the principle of “minimizing misoperation on the basis of not refusing protection,” a relatively complete steam turbine thermal engineering was proposed based on the prevention of steam turbine over speeding accidents caused by pumping backflow. Protection of the redundant transformation of technical programs.
