摘　　要：为了改善汽轮机组低负荷运行时的经济性,介绍了某电厂东汽超临界600 MW汽轮机组低负荷运行优化的情况。按照机组的实际运行状况和自身特点,先通过高压缸调节门管理曲线优化,实现了顺序阀控制方式,然后进行滑压运行优化,得到了机组优化后的滑压运行控制曲线。通过优化前后的热效率对比试验,表明优化后的运行方式有效地提高了机组低负荷运行时的经济性。The optimization of low load operation for a supercritical 600-MW steam turbine made by Dongfang Steam Turbine Co.Ltd.is presented to improve the economics of the unit under the low load condition.According to the unit practical operation status and its own characteristics,first the sequence valve control mode is adopted through optimizing the management curve for the HP control valve,and then the optimized control curve of sliding pressure operation is gained by optimizing the sliding pressure operation.The tests for comparison between the thermal efficiency before and after the optimization are performed,which indicates that the optimized operation mode can effectively improve the unit economics under the low load condition.
