摘要
介绍了西门子 7U微机发电机—变压器组保护装置的基本功能 ,对西门子 7U发变组保护的原理 :差动保护 ,失磁保护 ,定子一点接地和转子一点接地保护进行了分析。并对大型发变组保护提出了 7U的配置方案。
The basic functions of Siemens LSA7 microprocessor based protection devices for generator transformer bank are presented. The configuration of LSA7 protection devices for high rating generator transformer bank are put forward. At the same time, the principles of Siemens LSA7 protection series such as differential protection, field loss protection, stator one point grounding fault protection and rotor one point grounding fault protection are analyzed in detail.
