F级燃气—蒸汽联合循环机组降低厂用电率措施

Measures of Reducing Auxiliary Power Ratio by F Gas-Steam Combined Cycle Units

从机组启动次数、机组负荷率、辅机运行方式、电气设备和其他因素五方面对影响厂用电率的因素进行了研究和分析,从优化辅机运行方式、优化电气设备运行方式、设备技术改造三方面具体阐述了F级燃气—蒸汽联合循环机组降低厂用电率的可行措施,为降低燃气—蒸汽联合循环机组的厂用电率,提高电厂经济效益提出了有效的解决方案。

The factors influencing auxiliary power ratio are researched and analyzed from five aspects: the unit startups,load rate,auxiliary operation mode,electrical equipment and others. The feasible measures to reduce auxiliary power ratio by F gas-steam combined cycle units are elaborated from three aspects: optimizing auxiliary operation mode,optimizing electrical equipment operation mode and technically reforming equipment. Thereby,effective solutions are proposed to reduce auxiliary power ratio by F gas-steam combined cycle units and improve profits of power plants.
