摘要
用等值辐射网络分摊输电损耗是一个全新的思路。文中分析发现已有方法没有充分利用实际输电网络的结构与潮流状态,且存在以辐射网络的支路导纳为待求量去求辐射网络不能解决发电机与负荷同节点的问题。文中方法通过引入实际输电网络发电机与负荷之间的点对点损耗灵敏度,可比较充分地利用实际网络的结构与潮流状态;以辐射网络中支路上的潮流作为待求量,可解决发电机与负荷同节点问题。一个包含4台发电机6个负荷节点系统的计算结果验证了文中方法的合理性。
It is a new idea to allocate losses by using a radial equivalent (RE) network. However the existed methods have not taken full advantage of topology and power flow of actual network and they cannot deal with the problem of node connecting generators and loads by setting the admittance of branches of RE network as the objective quantity. The algorithm proposed in the paper takes full merit of the incremental transmission loss coefficients between generators and loads. Hence it can fully reflect topology and power flow of actual network. The algorithm sets the active power flow in the branches of RE network as the objective quantity to deal with the problem of node connecting generators and loads. Finally, calculation results of a 4-generator 6-node system illustrate the rationality of the proposed loss allocation algorithm.
