摘要
首先对配电网馈线的负荷和长度进行简化假设,并定义了主干线和分支线;在考虑馈线配变容量约束的基础上,提出了转供率计算方法;把配电网馈线分为主干线、分支线和配变,并由此推导出配电网馈线可靠性指标,利用馈线可靠性指标形成配电系统可靠性指标,另外对网架假设进行误差分析。最后分析了规划配电网可靠性评估需要的数据结构;算例证明了对规划配电网假设和该算法的有效性和可行性。
The load and length of distribution feeder are simplified by assumptions and the main line and branch are defined.With the consideration of feeder transformer capacity constraint,the calculation method of load transfer rate is proposed.The feeder is divided into main line,branch and distribution transformer,and the reliability indices of distribution feeder are then deduced,based on which the system reliability indices are formed.Error analysis is carried out for the network assumptions and the data structure needed for the reliability evaluation of distribution network planning is analyzed.An example shows that the proposed assumptions and algorithm are effective and feasible.
