摘　　要：结合三峡机组励磁系统的调试及投运经验,对大型水电机组静止自励系统选型中存在的一些关键性技术课题进行分析与论证,期望得出的结论有助于在大型水轮发电机组励磁系统参数选择和在提高机组运行安全、可靠性方面提供有益的借鉴。文中提出的励磁系统设计新理念仅代表个人的观点。This paper analyzes and discusses the key technology problems in selecting of static excitation system for large-scale hydro-generator units combined with the practical experiences in Three Gorges excitation system commissioning and operating. It is hoped that the conclusions are useful and beneficial for selecting of excitation system parameters and improving the operation safety and reliability of large-scale hydro-generator unit. The viewpoints of new concept for excitation system design presented in the paper are individual only.
