摘　　要：快速准确地定位配电网故障区间对缩短故障停电时间和恢复电网运行具有重要的意义。提出了基于正弦与余弦优化算法(Sine Cosine Algorithm,SCA)的配电网故障区间定位方法。SCA算法通过简单的正弦与余弦函数模型即可实现优化问题的全局快速搜索,具有原理简单,容易实现,搜索能力强等特点。算例对比分析了SCA算法定位结果的快速性与准确性,探讨了算法参数对定位结果的影响。仿真结果表明,SCA算法在单点与多点故障并伴有信息丢失畸变等情况下均表现出了良好的优化性能。Locating the fault section in distribution network quickly and precisely is crucial for reducing the outage time and resuming the operation. A fault section location method based on sine cosine algorithm （SCA） is proposed. SCA has the capability of searching the optimal solution using mathematical model based on sine and cosine fimctions. It is with advantages of simple principle, easy implementation, and strong search ability. Simulations are designed to comparatively analyze its accuracy and rapidity, and investigate the influence of algorithm parameters. The results show that SCA performs well on single and multiple faults with distorted and/or lost information.
