摘　　要：励磁系统作为调相机的重要组成部分,其可靠性直接影响调相机的运行特性。随着技术的进步,励磁系统日趋成熟,励磁控制器也从传统的模拟式发展到微机数字式。然而在实际运行中,仍会因为某些因素导致励磁系统故障,从而引发设备故障导致跳机。通过对某厂站励磁系统故障进行分析,提出相关改进措施,为后续设计、施工、验收及运行维护提供经验参考。As an important part of the synchronous condenser,the reliability of excitation system directly affects the operating characteristics of the synchronous condenser.With the development of technology,the excitation system is becoming more and more mature,and the excitation controller has also developed from the traditional analog to the digital.However,in the actual operation,some factors still lead to excitation system failure,which leads to equipment failure and tripping.In this paper,through the fault analysis of excitation system in a power station,relevant improvement measures are proposed,which can provide relevant reference value for subsequent design,construction,acceptance and operation and maintenance.
