摘要
良好的励磁系统对改善电力系统安全稳定运行,保证可靠的电能质量有着重要的意义。结合现场一起功率整流柜风机停运故障现象和试验数据,分析故障原因,提出了解决方法和改进措施,有效提高励磁系统及发电机组的运行稳定性,为类似励磁系统的故障处理和设计方案优化提供参考。
A good excitation system is of great significance to improve the safe and stable operation of power system and ensure reliable power quality. Combined with an onsite fan shutdown fault and test data of a power rectifier cabinet, the cause of the fault is analyzed, and the solutions and improvement measures are proposed so as to effectively improve the operation stability of the excitation system and the generator set, which offers reference for the fault treatment and design scheme optimization of similar excitation systems.
