电力系统继电保护课程设计作业及详细课程设计(15)

XT1*=XT2*=XT3*=XT1/ZB=38.413/132.25=0.2904 ②变压器T4、T5等值电抗计算：

XT4= XT5=(UK%/100) ×( UN2×103/SN) =60.5Ω XT4*=XT5*= XT4/ZB =0.5/132.25 =0.457 ③变压器T6、T7等值电抗计算：

XT6= XT7 =(UK/100) ×(UN2×103/SN) =41.984Ω XT6*= XT7*=XT6/ZB=41.984/132.25=0.317 ④变压器T8等值电抗计算：

XT8= (UK%/100)×(UN2×103/SN)≈38.413Ω XT8* = XT8/ZB =38.413/132.25=0.2904 (3)发电机等值电抗计算

①发电机G1、G2电抗标幺值计算
