辐射状配电网络方程的研究及应用

Radial Distribution Network Matrices and Their Applications

配电系统表现出与输电系统不同的特点．它一般是环形网络开环运行，其支路参数ｒ与Ｘ相差不大，甚至有时ｒ＞ｘ．以至在输电网中行之有效的潮流分析方法，如快速分解法，在配电网中效率很低．本文的研究表明：在适当的条件下，辐射状配电网络的节点导纳阵因子表可直接写出．无需因子分解过程；节点阻抗阵也可直接写出，计算量极小．这一特性已被成功地应用于配电系统的无功电压控制中，还可用于配电网络重构中．

Radial distribution network matriccs are studied, and some attractive results arc obtained in this paper. Under some conditions,the factor matirccs of the nodal admittance matrix, and the nodal hopedance matrix can be directly written out without complicated calculahons in a distribution system.Theal features have been applied to power now calculahon, voltage / var control and network reconfiguration, etc.
