潮流追踪迭代算法

该文在对潮流流动机理进行深入分析的基础上，提出了一种新的快速准确潮流追踪算法，在潮流追踪过程中，考虑了有功与无功功率之间的影响，是完全意义上的有功和无功功率追踪，算法中采用了有功功率与无功功率追踪的迭代进行方式，从而克服了在有功与无功功率通路不同的情况下无法进行准确追踪的困难。由于充分利用了电压分布的特点，将节点电压的幅值和角度作为水平位分别对有功和无功功率进行追踪，在确定节点追踪顺序中避免了对节点和线路的搜索，可显著提高计算速度，因为该算法中同时对有功和无功功率进行追踪，故计算结果准确，该算法直观，清晰，计算快速，准确，数字算例表明，文中的观点是正确的，所提出的迭代算法是有效的。

AN ITERATIVE LOAD FLOW TRACING METHOD

Based on the thoroughly analysis of the power flow mechanism, a fast a nd accurate power flow tracing method is proposed. The power losses are allocate d according to the proportion of complex power when tracing power flow, so the a ctive and reactive power are traced in the same time. The difficulty that accura te tracing results can not be gain in some cases could overcome for the active a nd reactive power flow tracing are carried on iteratively in the algorithm. The distribution of bus voltage is made full use of, as the angle and magnitude of t he bus voltage are used as level to trace active and reactive power respectively . As a result, the research of buses and transmission elements can be avoid and the computation speed can be enhanced notably. The tracing results are accurate, for the active and reactive power are traced in the same time. The proposed met hod is directly perceived through the senses, fast and accurate in computation, so the method can be accepted easily by electric power company. Case study shows that the viewpoint in the paper is correct and the proposed method is valid and feasible.
