摘　　要：为了校验并解决进线档最小相间距离的工程实际问题,建立进线档相导线的任意一点三维数学模型,通过改进粒子群算法,快速精确计算进线档相邻两相的最小相间距离。运用MATLAB程序仿真分析了相邻相的最小相间距离与档距、相导线张力、挂点高差的关系。仿真结果表明随着档距的增大,相邻两相的最小相间距离增加较快,随后增加趋势变缓;相邻两相的最小相间距离随着某一控制相的导线张力变大而减小;相邻两相的最小相间随挂点高差的增大而迅速减小。最后指出,敏感因素均有一临界值,超过该临界值,相邻两相的最小相间距离不满足合格距离要求。In order to solve engineering problem with the minimum phase distance of approach span,this paper establishes 3D mathematical method with every dot on the transmission line.The study can calculates the minimum phase distance based on the improved PSO algorithm quickly and accurately.It also analyzes the relationship between the minimum phase distance and the distance of the approach span,conductor tension,level difference on the MATLAB simulation.The simulation results show that with the increasing of span,the minimum phase spacing increases rapidly and then slow down;the minimum phase has a decrease with the conductor tension increased;the minimum phase decreases rapidly with the increase of level difference.At last,this paper points out that the sensitive factors have a critical value.If the sensitive factors exceed the critical value,the minimum phase can’t be substandard.
