水轮发电机轴线摆度增大的原因分析

Analysis on the Cause of Increasing Axial Pendulum of Hydrogenerator

水轮发电机主要是指以水轮机为原动机将水能转化为电能的一种发电机,当水流经过水轮机时,水能即可转化为机械能,水轮机的转轴带动着发电机的转子,将机械能转化为电能进行输出,水轮发电机助于水电站生产电能最主要的一种动力设备。在水轮发电机运行的过程中,水轮发电机轴线摆度属于判断水轮机工况的重要参数之一,水轮发电机轴线的摆度会出现异常增大的现象,这种现象的出现严重影响水轮发电机的正常运行及工作效率,为了分析水轮发电机轴线摆度增大的相关原因及解决对策,笔者针对水轮发电机的相关方面进行了分析。

Hydroelectric generator mainly refers to a generator that converts water energy into electric energy with turbine as prime mover. When water flows through turbine, water can be converted into mechanical energy. The turbine shaft drives the rotor of generator, The mechanical energy into electrical energy for output, hydropower generators to help the production of electric power is the most important power equipment. During the operation of the hydro-generator, the axial swing of the hydro-generator is one of the important parameters to judge the turbine condition. The swing of the hydro-generator axis will increase abnormally. This phenomenon is serious Which is related to the normal operation and working efficiency of the hydro-generator. In order to analyze the relevant reasons and solve the countermeasure of the increase of the axial swing of the hydro-generator, the author analyzes the relevant aspects of the hydro-generator.
