摘　　要：针对超超临界机组高加跳闸后影响机组安全性问题,本文以1000MW机组为工程应用背景,分析了高加跳闸后机组负荷、中间点温度、主蒸汽温度等主要参数变化规律,提出了高加跳闸后热工控制逻辑,通过机组现场实际试验予以验证。试验结果表明,热工控制逻辑符合实际情况,有效保障高加跳闸后机组的安全性。In view of the unit security issues caused by ultra supercritical unit after its high-pressure heatertripping,this paper analyzes the change rules of unit load,intermediate point temperature,main steam temperature and other main parameters after the tripping on the engineering application background of 1000 mwunit. And it puts forward the thermal control logic after tripping,and it has been verified after actual test.And the results show that the thermal control logic conforms to the actual situation and guarantees the unitsecurity after high-pressure heater tripping.
