Abstract:

基于广度优先搜索算法构造了复杂配电网络的等效模型,采用区域节点行向量法对复杂配电网络进行了可靠性评估。给出了区域节点的定义,采用广度优先搜索算法将复杂配电网络等效为由区域节点和开关元件组成的模型,采用区域节点行向量法得到了负荷节点和系统的可靠性评估指标。在该模型和算法中,区域节点的形成算法以支路为研究对象,操作简单,网络适应性强。采用区域节点行向量法对复杂配电网络进行可靠性评估时,便于考虑开关装置故障的影响,实用性较强。RBTS-bus6系统的评估结果及其与现有分区方法的比较结果表明了该模型和算法在简化网络和提高运算速度方面具有明显优势,在适应网络结构变化方面具有较好的鲁棒性。
