摘　　要：定位开关死区故障是改进馈线自动化处理的关键,由于故障特征复杂多样且可能受多种因素的影响,确保故障检测的准确性是一个挑战,因此提出一种基于配电网开关死区故障的改进馈线自动化处理方法。通过引入蚁群算法,调整蚂蚁核心转移概率的设定,使其更具灵活性和适应性,克服不同信息素之间的干扰,对开关死区故障实现准确定位。计算电压、电流及馈线向量,建立馈线自动化方程并设计合闸闭锁流程,由此建立改进馈线自动化处理方案。实验结果显示,改进的馈线自动化处理方法可大幅提高对开关死区故障的快速隔离能力,减少电力系统的故障持续时间,切实提高了供电的可靠性。The location of switch dead zone faults is the key to improving feeder automation.However ensuring the accuracy of fault detection is a challenge due to the complexity,diversity,and multi-factor dependence of fault characteristics.Therefore this paper proposes a method of promoting the handling of switch dead zone faults to achieve improved feeder automation.The method first achieves accurate location of switch dead zone faults by introducing a modified ant colony algorithm in which the ant core transition probability is adjusted to enhance flexibility and adaptability and overcome interference between different pheromones.It then establishes feeder automation equations and formulates closing and latching processes by calculating voltage,current,and feeder vector,and consequently forms an improved feeder automation scheme.The proposed method has been elaborated by experiment capable of achieve significantly enhanced prompt isolation of switch dead zone faults,reduced duration of power system faults,and thus,improved power supply reliability.
