补充资料:水轮发电机组调相


水轮发电机组调相
compensating operation of water turbine generator set

shu!Iunfodronj一zut一oox旧ng水轮发电机组调相(eompensating operationof water turbine generator set)水轮发电机组只发无功功率,并消耗电力系统有功功率的一种运行方式。水轮发电机组的转轮在空气中或在水中都可作调相运行,根据中国官厅及密云两个水电站机组实测资料,在空气中运行一般吸取电力系统有功功率为水轮发电机额定功率的3写;在水中运行,吸取电力系统有功功率为空气中运行的10倍左右,所以,多采取水轮发电机组的转轮在空气中作调相运行。 水轮发电机组作同步调相机运行时,先以水轮发电机运行方式投人电力系统,然后关闭水轮机导叶,并把压缩空气通人水轮机室将水压下,使水轮机转轮在空气中运行,再凭借励磁调节作用(见水轮发电机励滋),向电力系统输出无功功率,起到调整电力系统电压的作用。在停止调相运行时,只要放出水轮机室压缩空气.水轮发电机组与系统解列,以水轮发电机组正常方式进行停机。 水轮发电机组进行调相运行的特点是起动快,消耗电力系统功率小,转换方式灵活。如果把水轮发电机组安装在负荷中心附近,作调相运行时效果则更好。 水轮发电机作调相机运行时,水轮发电机定子电流应降至相当于额定转子电流时的对应数值,此时额定功率因数为。.8的水轮发电机组,其定子电流大约降低20%。因此,机组调相容量的确定与额定功率因数有关,约为其额定容量的“%~80%。
