【摘要】 在城市中压配电网中,除了变电站直供方式的接线模式外,还有一种可靠性更高的接线模式,即带开闭所的接线模式。文中首先在配电网空间地理信息系统(GIS)的环境下结合变电站选址定容的方法确定了开闭所的最佳数量和最优位置,然后对开闭所进线的最佳网络结构进行了自动布局,并运用多分段多联络接线模式自动布局的方法对开闭所出线进行了自动布局,提出了在不同负荷密度条件下多种接线模式灵活布局的一般性处理方法。最后通过对实际算例的分析验证了文中所述方法的可行性。更多还原

【Abstract】 There is a special connection mode of even a higher reliability known as the switching station network in the urban MV distribution network apart from the substation direct supply connection modes. In this paper first the optimum number and location of switching stations are determined based on the spatial GIS of the distribution network. Then the method of substation locating and capacity calculating is adopted followed by the development of the automatic routing of the incoming lines and outgoing lines of switching stations based on the automatic routing of multi-sectioned and multi-linked network. After this, the general method of automatic routing of manifold connection modes under the condition of different load densities is proposed. It is shown from an analysis of the example that the method proposed is feasible.更多还原
