摘　　要：重型燃气轮机的变频起动回路设计直接关系到机组的运行安全。为确保机组起动的可靠性,要求起动系统实现冗余配置,但静止变频器(SFC)作为短时运行设备,绝大多数时间处于待机状态,存在设备投入大、设备利用率低等问题。本文介绍多种燃气轮机SFC起动系统的回路连接及应用情况,对各起动回路的优缺点进行分析,提出一种多个电厂SFC协同设计方法。实践表明,本文所提方法可在确保机组运行可靠性的同时提高设备利用效率、减少设备配置、降低项目投入,可为新建燃气轮机项目特别是扩建项目提供起动系统配置新方案。The design of variable frequency starting circuit for heavy duty gas turbine is directly related to the operation safety of the unit.In order to ensure the starting reliability of the unit,the starting system is required to implement redundancy configuration.As a short-time running equipment,the static frequency converter(SFC)is mostly in standby state.There are problems such as large equipment investment and low equipment utilization rate.This paper introduces the loop connection and application of gas turbine SFC starting system,and analyzes the advantages and disadvantages of each starting loop.A SFC collaborative design method for multiple power plants is proposed.Practice shows that this method can not only ensure the reliability of unit operation,but also improve equipment utilization efficiency,reduce equipment configuration and project investment.It provides a new starting system configuration scheme for new gas turbine projects,especially expansion projects.
