摘　　要：某电厂锅炉一次风机进行变频改造后,一次风机变频器频繁故障导致风机跳闸,跳闸后运行风机加载过程存在若干问题,严重影响该厂机组安全、稳定运行。通过分析一次风机变频控制的所有环节,有针对性地进行了优化改造,试验证明,此次优化改造达到了设计目的,为机组的安全、稳定运行打下了良好的基础。After the variable frequency reformation of the boiler primary air fan of a power plant,the frequency converter of the primary air fan failed frequently and led the air fan to trip,and after the fan tripped,some problems exist in loading process of the fan in restarting,which influence on safe and stable operation of the unit seriously.The all links of the variable frequency control of the primary air fan were analyzed,and targeted optimization reformation was carried out.The test shows that the opti-mization reformation realizes the design goal and provides good basis for safe and stable operation of the unit.
