新疆主电网发电机进相试验与分析

Leading-phase Test of Generator in Xinjiang Main Power Grid and Its Analysis

新疆主电网近几年发电机开展了进相运行,通过进相试验总结了这些发电机进相运行的特点。以吉林台水电站2号水轮发电机和玛纳斯发电厂3号汽轮发电机进相试验数据为例,利用曲线拟合的方法,得到发电机进相运行的P-Q及发电机定子端部温升的拟合曲线及拟合公式,并从拟合误差数据判断拟合的效果,在实际发电机进相运行具有一定的指导意义。

Through the leading - phase operation of generators in the main power grid of Xinjiang in recent years, the characteristics of leading - phase operation of these generators are summarized. Taking the leading - phase operation data of No .2 water turbo - generator in JiLinTai Hydroelectric Station and No. 3 turbine - generator in MaNaSi Power Plant for example and using curve - fitting method, the curve fitting and fitting formula about P - Q of leading- phase operation and temperature rise in stator end are obtained. According to fitting error, the result of the fitting is judged. The method can give some guidance in the actual leading - phase operation of generator
