喜河水电厂三台水轮发电机组稳定性试验结论及运行对策

Conclusion on Stability Test of Three Turbine - generators of Xihe Hydropower Station and the Operation Measures

喜河水电站的水轮机为轴流转桨式,发电机具有上导轴承的半伞型结构,投运后均有较大的振动,为此,对喜河水电厂三台机组进行稳定性试验,根据试验结论提出机组安全、稳定运行对策。

The axial flow feathering water turbine was adopted for the Xihe hydropower station. The generator has an umbrella type structure with an upper guide bearing. Because larger vibration occurred when the unit put into operation, the stability test was conducted. Based on the test, some conclusion was made and the counter- measures put forward for safety and stable operation.
