rotational inertia of hydrogenerator
shullun fodlonl一zhuondong guonl旧ng水轮发电机转动惯.(rotational inertia ofhydrogenerator)水枪发电机转动惯盆是发电机转动部分的重tG与其惯性直径D平方的乘积，用GDZ表示，也称为转动部分的飞轮力矩。 转动惯量表明电力系统出现大干扰时，水轮发电机组转动部分保持原来运动状态的能力，所以对电力系统的暂态过程和动稳定有很大影响。转动惯t对水轮机调节保证计算也有很大影响，转动惯t大，机组甩负荷后的转速上升率如保持一定值，则可允许较大的压力上升率，从而可以减小引水钢管直径或允许增加钢管长度，甚至不设调压井.但增大转动惯t将增加发电机重量和造价，也延长了机组的起动时间。 当水轮发电机基本尺寸确定后，转动惯量GDZ值可按下列经验公式计算 GDZ=kD户·”1.式中D为定子铁芯内径，m‘l:为定子铁芯长度，m;h为经验系数，一般可按表选取。 经脸系傲裹┌────────┬────┬────┬────┐│机纽转迫(r/成.) │<100 │100~375 │>375 │├────────┼────┼────┼────┤│经玻系狱《k) │5 .2~5.5│5.1~5。3│4.5~5.0 │└────────┴────┴────┴────┘ 大容量低转速水轮发电机组的转动惯t最大已达450000 tf·mZ(4410 kN·mZ)
