摘要(Abstract)：

定子接地保护与故障定位是发电机保护的重要组成部分，其动作的准确性直接关系到发电机以及电力系统的安全稳定运行。为提高对定子接地故障的灵敏切除和快速定位能力，从定子接地保护和接地故障定位两个方面综述了当前的研究进展。首先，梳理各类型定子接地保护方法的原理、特点和局限性，总结近年来相应的改进成果，并阐述对于定子接地保护选择性问题的解决方案。其次，评述现有定子接地故障定位方法的原理和优缺点，探讨进一步提升定位精度的关键因素。最后，对定子接地保护以及故障定位技术未来可能的改进方向进行了展望。
Stator ground protection and fault location are a critical component of generator protection. To enhance the capability for sensitive clearing and rapid location of stator ground faults, this paper summarizes recent research advances from two key aspects: stator ground fault protection and ground fault location. Firstly, it examines the principles, characteristics, and limitations of various types of stator ground protection methods, summarizes corresponding improvements in recent years, and elaborates on solutions to stator ground protection selection. Secondly, it assesses the principles, advantages, and disadvantages of existing stator ground fault location methods, discussing key factors for further improving location accuracy. Finally, it offers perspectives on potential future improvements for stator ground protection and fault location techniques.
