Abstract: Microcomputer excitation system is an important part of generator operation control. This paper compares the NARI's SAVR2000 to the Exc 9000 microcomputer-based self-excited excitation system of Guangzhou Institute of Electrical Science. By comparative analysis of the excitation regulator power supply, real-time fault diagnosis, silicon-controlled rectifier bridge operation mode and comparison of the PT disconnection criterion, some conclusions and recommendations were advanced and a solid foundation for future operation and management was laid.

摘要: 微机励磁系统是发电机运行控制的重要内容之一,结合南瑞的SAVR2000、广州电器科学研究院的Exc9000 型自并激微机励磁系统从励磁调节器电源、实时故障诊断、可控硅整流桥投运方式、PT 断线判据的比较几个方面进行对比分析,得出一些结论和建议,为今后的运行管理奠定更扎实的基础。
