摘要
对广东省电力试验研究所曾进行的大型汽轮发电机定子绕组端部固有频率测试及模态分析工作进行了总结 ,并将测试结果与实际的事故或缺陷现象进行比较分析 ,说明了该项测试技术的先进性和准确性 ,最后指出了应进一步开展的工作。
The natural frequency measurement and mode analysis for large turbo-generator stator end-winding conducted by Guangdong Power Tes t & Research Institute are summed up in this paper. The advance and veracity of this technology are shown by comparing the test results with actual faults. It i s also pointed out what should be developed.
