中文摘要:
      分布式电源接入配网会影响配网故障定位。本文提出了一种基于最小故障电抗概念、利用Fibonacci搜索算法的含分布式电源配网故障定位方法。首先分析了不同配网故障类型下最小故障点抗法计算故障电抗的方法；然后提出了Fibonacci搜索算法来估计故障距离,该方法使用的搜索点数更少、搜索步长不全依赖故障电抗准确度。提出了基于Ladder的潮流计算方法,以估计每个分布式电源对故障电流的贡献值。该方法仅利用分布式电源节点的智能电子设备提供的同步电流量测相量。最后利用IEEE34节点分析了故障电抗的影响、故障距离的影响、负荷波动的影响和分布式电源量测误差场景下故障定位误差,并对比其他求解方法说明了本文提出方法的有效性和准确性。
