Our country has largely invested in reconstruction of city electric power network in past years . it strength the supply ability of high - voltage network . but there are still many problems in middle and low voltage network result from the neglect of it 近几年国家投入巨资进行城网改造,使高压输、配电网的供电能力大大加强,但长期以来因为对中、低压配电网络缺乏足够的重视,致使目前中、低压配电网存在的问题还较多。
In this paper global joint planning for middle and low voltage network is considered . both line arrangement and cross section and transformer arrangement and rate are considered . it is a non - line combined optimum problem more complex than single network planning 本文从整体的角度考虑中压和低压配电网络的联合规划,不仅考虑了线路走向和导线截面大小,而且考虑了变压器的布置位置和容量,这是一个比单纯的网架规划更复杂的非线性组合优化问题。
