合理分摊和回收输电成本对激励电网、电源和负荷的合理规划/选址，以及整个电力系统的安全与经济运行具有重要意义。输电成本分摊的核心问题是源流关系分析，或使用程度分析、潮流跟踪、功率分解、电气剖分等。目前并没有统一的、被广泛认可的方法来评价现有的多种源流分析方法的优劣。在此背景下，首先对源流分析方法的评价问题进行了讨论，并通过算例说明了影响源流分析方法适应性的因素，包括应用领域、不同节点的发电及负荷效益等。然后发展了一种用于输电固定成本分摊的基于社会综合效益/社会剩余最大的源流分析方法，在确定某电源所供给的负荷时，综合考虑了输电成本、发电成本和用电效益。最后，通过算例对所提出方法与现有方法进行了比较分析，并说明了所提出方法的基本特征。

Properly allocating transmission costs among network users plays a key role in providing appropriate economic signals for planning and siting of generation,transmission and demand sectors,and hence for the secure and economic operation of the whole power system.One of the most important and yet difficult issues associated with transmission cost allocation is the so-called source-sink analysis problem,or in other words,the network use degree evaluation,power flow tracing,power flow separation,or electrical dissection.Up to now,there does not exist a widely accepted approach for making reasonable comparisons among various source-sink analysis methods.Given this background,the problem of how to evaluate various source-sink analysis methods is first addressed.Then,a source-sink analysis method for transmission fixed cost allocation is developed with an obj ective of maximizing social surplus,in which the generation cost,transmission cost,and customer benefit are all taken into account.Finally,a sample system is served for demonstrating the developed method and for making comparisons among the developed method and several existing methods.
