摘要
本文根据电力系统三相对称短路的特点,建立了合理的三相短路的数学模型,在此基础上,形成电力系统短路电流实用计算方法:节点阻抗矩阵的支路追加法。编制了对任意一个电力系统在任意点发生短路故障时三相短路电流及其分布的通用计算程序。该办法适用予各种复杂结构的电力系统。从一个侧面展示了计算机应用于电力系统的广阔前景。
In accordance with the characteristics of three—phase symmet- rical short circuit of power system,this paper presents a rational mathematical model describing three—phase short circuit.It then proposes a practical com- putational method called branch add—on methol for node matrix,which is suitable for calculation of short—circuit current of power system,Finally,it gives a general—purpose program for three—phase short—circuit current and its distribution to the short—circuit failure of an arbittrary point in powen system.The proposed method can be appiled to various Power systems with com- plex structure,which has shown the wide perspective of computer applications in power system from one aspect. ~ :~ ~ ~ . .' ~
