摘　　要：针对极端天气下配电自动化系统易发生大面积通迅故障的问题,提出一种考虑馈线终端装置(FTU)信号丢失的有源配电网故障定位方法。该方法以现有的基于优化算法的有源配电网故障定位模型为基础,在模型中添加表示FTU上传过流信号是否丢失的决策变量,增加FTU信号丢失约束并对适应度函数进行修改,并将模型转化为整数线性规划模型,利用商业求解器进行求解。最后,通过不同故障场景测试验证了所提方法在大规模FTU信号丢失状态下仍有较高的容错性。Aiming at large-scale communication failures in distribution automation systems during extreme weather,this paper proposes a fault location method for active distribution networks that takes into account Feeder Terminal Unit(FTU)signal loss.The method is based on the existing fault location model using optimization algorithms,and it adds decision variables indicating whether the FTU overcurrent signals are lost,incorporates FTU signal loss constraints,and modifies the fitness function.The model is transformed into an integer linear programming model and solved by commercial solvers.Finally,tests under different fault scenarios verify that the proposed method maintains high fault tolerance even with large-scale FTU signal loss.
