摘要
提出基于配电网分层分区的区域节点广度优先搜索法的复杂配电系统可靠性评估方法,按照配电系统的电压等级对进行分层评估,不同电压等级内按照提出了区域节点定义方法,并利用广度优先搜索的方法进行可靠性评估。通过对IEEE测试系统的评估证明了该方法的正确性和有效性。在该模型和算法中,区域节点的定义使区域划分更直接有效,其形成算法以支路为对象,操作简单,网络适应性强;利用新区域节点行向量进行可靠性评估,便于考虑开关装置故障的影响,使其更具实用性。通过与现有分区方法的比较,证明了该模型和算法在简化网络提高运算速度上有显著优势,在适应网络结构变化方面具有更好的鲁棒性,具有一定的理论价值和现实指导意义。
A new reliability evaluation method of complex distribution system is proposed based on distribution system delaminating subareas and Breadth First Search.The distribution system is divided into different layers and subarea according to voltage level and defined the area node in each voltage level.The reliability evaluation is carried out using Breadth First Search method.The simulation results of RBTS bus 6 proved the validity.In the new evaluation process,the zone node definition makes the subarea partition more direct and more efficient, its analysis object becomes the branch which also makes the process simple,and the adaptability of the method to different distribution system is improved.Comparing the evaluation results of the new method with the traditional methods,it is proved that the new method is more rapid and has a better robustness in the variety of network configuration.
