摘要
为解决小电流接地系统故障测距问题，以１０ｋＶ配电网为具体研究对象，对故障率最高的单相接地故障进行了分析研究，建立了网络故障状态下的数学模型，并首次将模拟退火算法应用到小电流接地系统的故障测距问题中，解决了算法应用中的一系列问题，取得了令人满意的计算结果，其测距误差远小于技术要求值。
The aim of this paper is to solve the problem of Fault-Location in weak Current Connecting to Earth System,it chooses the electric power distribution network of 10kV as its subject.It analyses and researches a single-phase connecting to earth's fault that has the hightest fault ratio and form mathematical model under network fault state. The Simulated Annealing Algorithm is applied to fault-location in weak current connecting to earth system for the first time.It solved a series of problems in applicating Simulated Annealing Algorithm.It's proved by the simulating experiment that the Location Error of Fault recognition is far less the requirement.
