摘　　要：介绍了某电厂超临界600MW机组滑压优化运行的试验研究。通过分别在510MW、480MW、420MW、360MW、300MW工况下进行定滑压运行性能对比试验,得到了机组调门管理曲线优化后的滑压运行曲线。新的滑压运行方式有效地降低了汽轮机热耗率,提高了机组变负荷时的运行经济性。The test study on optimization of sliding pressure operation for the super critical 60OMW unit has been presented. The sliding pressure curves were gained by performance comparison tests of fixed and sliding pressure operation under 510MW,480MW,420MW,360MW,30OMW,after optimization of the steam-governing valve control curves. The new sliding pressure operation mode make the heat rate of steam turbine to be lowered effectively, and make the operation economy of varying load to be improved.
