| 摘 要： | 目前国内特大型水电站励磁变保护配置，通常采用励磁变配有电流速断保护和过电流保护或励磁变配有电流差动保护和过电流保护．据此对励磁变保护配置进行分析，对于特大型水电站励磁变保护配置，推荐以电流差动保护为主保护，以过电流保护为后备保护．可为一些静止自励系统工程引为参考和借鉴．

| Abstract: | The current situation of protection configuration of excitation transformer in oversize hydropower stations is talked about in this article, as well as requirements of excitation transformer protection configuration in relevant norms. The highlights of the two excitation transformer protection configuration programs--differential protection and break protection--are also discussed, and the pros and cons of the two schemes are comparatively analyzed. Differential protection is recommended for the protection configuration program in oversize hydropower stations, hoping to provide reference for some static self-excitation system projects. |
