摘　　要：为提高有源配电网故障区段定位的精度和容错性能,构造了面向有源配电网的故障区段定位数学模型,在此基础上提出一种融合鲸鱼优化算法和教学优化算法的WOA-TLBO故障区段定位方法,充分利用了WOA的全局探索优势和TLBO的快速收敛优势。以含多个分布式电源的有源配电网为例进行了仿真测试,结果表明,所提故障区段定位方法能够在有源配电网发生短路故障时实现快速准确的区段定位,并具有良好的容错性。In order to improve the accuracy and fault tolerance of the fault section of the active distribution network,this paper formulates a mathematical model of the fault section locating for the active distribution network.On this basis,a fusion method which combines the whale optimization algorithm and a teaching⁃learning⁃based optimization algorithm is proposed.The WOA-TLBO fault section location method makes full use of the global exploration advantage of WOA and the rapid convergence advantage of TLBO.Taking an active distribution network with multiple distributed power sources as an example,a simulation test has been carried out.The results show that the proposed fault section location method can achieve rapid and accurate section location when a short⁃circuit fault occurs in the active distribution network,and has good fault tolerance.
