摘　　要：根据华北电力科学研究院有限责任公司多年来进行的励磁调节器设备入网性能检测试验的实际情况,介绍了国内外不同厂家生产的励磁调节器产品的功能设计特性,并从"网源协调"的角度进行涉网性能分析评估,指出其特性对电网稳定和机组安全的影响。文中重点分析了入网性能检测中发现的一些有代表性的典型问题,其中包括励磁调节器功能不符合标准要求、逻辑判据和参数设置不合理、程序设计不正确以及功能设计不完善等重大问题,尤其是TV断线、欠励限制、过励磁限制和PSS等6大类关键问题。这些问题严重影响发电机励磁系统的动态调节性能,对发电机安全及电力系统稳定带来重大影响。According to the performance tests of automatic voltage regulator （AVR） for grid access conducted by North China Electric Power Research Institute Co. Ltd. in recent years, the functions and design characteristics for various AVR by different manufacturers both at home and abroad were introduced. The analysis and evaluation of grid access performance showed the influence on grid stability and unit safety. Some typical problems occurred in grid ac- cess tests were highlighted,including nonconforming AVR functions,irrational logics and parameters setting,incorrect program design and imperfect function design and some vital problems,especially 6 major problems such as TV wire break,under excitation limit,over excitation limit and PSS etc. These problems severely affected AVR dynamic regu- lation, generator safety and system stability.
