摘　　要：某电厂配备两套6FA型燃气-蒸汽联合循环机组,燃气轮机启动阶段采用静态变频启动装置(SFC)驱动燃气轮机发电机转动,然后通过变速齿轮箱带动燃气轮机转动。通过某公司静态变频启动装置运行过程中的故障案例分析,准确判断出故障点,提出具体解决方案,保障了静态变频启动装置的可靠运行。通过此类故障,可以给同类型发电企业遇到同样问题时,提供参考依据。A power plant was equipped with two sets of 6FA gas-steam combined cycle units.During the startup phase of the gas turbine,a static frequency converter(SFC)was used to drive the gas turbine generator to rotate,and then the variable-speed gearbox drove the gas turbine to rotate.Through the analysis of the fault cases of a certain company's static frequency converter during operation,the fault locations were accurately determined,and specific solutions were proposed to ensure the reliable operation of the static frequency converter.Such faults can serve as a reference of solution for power generation enterprises of the same type to address similar issues.
