| 摘 要： | 电网源流分析,即确定电网的潮流分别由哪些部分组成,由哪些元件、节点功率或电网用户引起,是电力系统运行分析中许多问题的基础.但由于电网的一些特殊性质,到目前为止还没有得到广泛认同的方法.文中对直流分布因子方法、基于电流的方法、交流灵敏度方法以及潮流跟踪方法这4种目前常见的电网源流分析方法,分别从采用的简化与假设、功率平衡方法、分配对象及分析结果4个方面进行了对比,分析了各自适用的场合,探讨了各种方法的异同和优缺点,并采用算例进行了验证.

| Abstract: | The problem of power flow composition analysis,or the analysis of the composition,source,motivation and fate of each branch or element in a power system,is the crucial issue of many problems in power system analysis.But owing to the special characteristics of electric power networks,so far no commonly accepted power flow composition analytic method has yet been reported.Four commonly used methods of network power flow composition investigation,namely,the DC distribution factor method,the current-based metho... |
