摘　　要：G60数字式发电机保护在现代大型机组中应用广泛,对其应用进行分析总结有着重要的现实意义。简要介绍了G60发电机保护装置的软件、硬件构成及其特点,着重对发电机定子单相接地保护、失磁保护、失步保护等模块的原理进行了分析研究,提出了在保护模块选用、逻辑构成及整定中应当注意的问题,并针对实际应用中出现的具体问题,提出了相应的意见与建议。以期对G60发电机保护的应用提供有益参考,促进发电机保护运行水平的不断提高。G60 digital generator protection relay has been abroad applied in modem large-scaled generating unit, thus analysis and summary are practically necessai＇y in the application. The software and hardware architecture and their feature are briefly presented firstly. This paper emphaseses the research on the theory of generator stator ground protection, loss of excitation protection and out-of-step protection. And then, some problems needed to pay attention to in the process of the choice of protection block, logic and setting are presented. In allusion to concrete problems in the application of G60, relevant ideas and suggestions are presented. It is expected to do something useful to the application of G60 generator protection relay and promote the running level of generator protection.
