摘　　要：介绍了哈尔滨汽轮机有限公司制造的1 000 MW级发电机组汽轮机的设计热耗特性和配汽优化试验情况,包括配汽优化方案和实施后的效果。对该型汽轮机进行变工况试验后表明,相对于定压运行方式而言,采用复合滑压运行方式有利于提高机组的高压缸效率,降低给水泵动力消耗,但是循环效率随新蒸汽压力的降低而降低,因此滑压运行参数存在一定的优化空间。此优化方案可供同类机组设计时参考。The heat loss characteristics and steam distribution optimization experiment of 1 030 MW turbine manufactured by Harbin Steam Turbine Co., Ltd. are introduced, including steam distribution optimization scheme and its effect. Through the turbine test with condition variation, the results show that hybrid sliding-pressure operation is more beneficial to improve the efficiency of HP cylinder and reduce the power consumption of feedwater pump than fixed pressure operation, but the cycle efficiency will decrease with the decrease of new steam pressure. Therefore, there is a certain space-optimized in the parameters of hybrid sliding-pressure operation. This optimization design could provide references for the design of similar units.
