摘要
随着输电系统的开放 ,人们越来越要求按照线路的实际使用情况收费。该文利用图论快速计算输电线路的功率组成和发电机与负荷间的实际功率输送关系 ,从而为输电服务收费提供合理的依据。文中证明了两个有关定理 ,介绍了新的潮流跟踪方法。该方法以交流潮流的计算结果为基础 ,快速、有效地计算发电机对线路功率的贡献因子和负荷对线路功率的汲取因子 ,并进一步确定各发电机与负荷间的实际功率输送关系。所提方法也适用于实际系统中有功和无功功率输送关系的分析。
In this paper, graph theory is used to calculate the contributions of individual generators and loads to line flows and the real power transfer among individual generators and loads that are significant to transmission open access. Relevant lemmas are proved which present the necessary conditions required by the method. Based on ac load flow solution a novel method is suggested which can decide downstream and upstream power flow tracing paths very fast and calculate the contribution factors of generations to the line flows and the extraction factors of loads to the line flows efficiently. The power transfer among generators and loads can also be determined. The suggested method is suitable for both active and reactive power tracings in real power systems. Numerical example verifies the validity of this method.
