摘　　要：国外燃机发电机的设计是以电网频率为60Hz的运行工况为前提,但是国内电网的额定频率是50Hz,对进口发电机的端部模态是否能满足中国电网特点存在较多疑问。本文分析了端部模态试验方法及评判标准,以GE的390H型号燃机发电机为案例,进行了端部模态特性试验验证分析,得出对于国外引进的燃机发电机需要重点关注端部振模特性的结论,并给出了相应的建议。The design of foreign gas turbine generators is based on the operating conditions of grid frequency of 60Hz,but the rated frequency of domestic grid is 50Hz.There are many questions about whether the dynamic characteristic of imported generators can meet the characteristics of China's power grid.The test method and evaluation standard of dynamic characteristic test on stator end windings were analyzed.The GE 390H gas turbine generator was used as an example,and the analysis of dynamic characteristic test on stator end windings was carried out,and finally.It was concluded that for the imported gas turbine generators,it was necessary to pay attention to dynamic characteristic of the end of Stator and the corresponding suggestions were given.
