基于改进网络等值和故障影响矩阵的复杂配电网可靠性评估OA北大核心CSCDCSTPCD
Reliability Evaluation of Complex Distribution Network Based on Improved Network-Equivalent and Fault Influence Matrix
针对含多级分支子馈线且分支线首端设有断路器保护的复杂配电网提出了一种可靠性评估算法.首先对网络进行两级简化处理,通过改进的网络等值法将向上的等效节点直接串接在分支开关下游,将上级网络对下级网络的影响视为向下展开所形成简单节点网络中的区域节点指标,在后续处理时再将该影响叠加到停电指标结果中.避免了传统网络等值可能带来的误差.随后导出了基于故障影响矩阵的指标计算方法,可快速计算出区域和负荷点的可靠性指标以及系统指标.算法考虑了各种开关故障和自动化开关…查看全部>>
A new method is proposed for the reliability evaluation of complex distribution networks,which consists of multistage subfeeders with breakers and protections installed.First,the complex distribution network is simplified into several simple node networks.The upward-equivalent node is connected to the branch switch directly in the improved network-equivalent method.The impact of the superior network on the lower network is treated as an area-node reliability…查看全部>>
