补充资料:短路容量
反映电力系统某一供电点电气性能的一个特征量。定义为(兆伏安)式中IK为该供电点发生三相短路故障时的短路电流,单位为千安。UN为该点正常运行故障前的相间电压,电位为千伏。若UN、IK取标幺值U壨和I壦,则该点短路容量的标幺值为由于U壨接近于1,所以W壦的倒数即该供电点的短路阻抗标幺值为
首先,短路容量是对电力系统的某一供电点而言的,反映了该点的某些重要性能:①该点带负荷的能力和电压稳定性;②该点与电力系统电源之间联系的强弱;③该点发生短路时,短路电流的水平。其次,短路容量也和整个系统的容量有关。随着电力系统容量的扩大,系统短路容量的水平也会增大。现在高压开关设备的额定容量中,已将短路容量改用短路电流值,如额定开断电流(千安)。
