Abstract

The invention discloses a power distribution network medium-voltage line route planning method based on city utility tunnels, and belongs to the technical field of power distribution network planning. The method mainly comprises the following steps: S1, establishing a medium-voltage line power supply planning area; S2, establishing a medium-voltage line route planning model; S3, optimizing a line route based on Dijkstra algorithm; S4, completing line connection on the basis of an increment shortest path method. The route planning is divided into two steps by establishing a medium-voltage line route planning model in power distribution network planning under the construction background of new city district utility tunnels: firstly using a shortest route method to primarily form a power supply network, and realizing optimization for cable route in grid to complete trunk line planning; and then completing line connection based on an increment shortest route method. Compared with a heuristic algorithm, the method has the characteristics of clear concept, high calculation speed and good planning effect. The planned power distribution network medium-voltage line is applicable to the construction condition of city utility tunnels, and is minimum in comprehensive investment cost and shortest in cable route.

Description

technical field [0001] The invention relates to the technical field of distribution network planning, and more specifically, relates to a method for planning a medium-voltage line path of a distribution network based on an urban comprehensive utility gallery. Background technique [0002] In 2013, the State Council promulgated the "Opinions on Strengthening Urban Infrastructure Construction", proposing that it would take about 3 years to start the pilot project of underground comprehensive pipe corridors in 36 large and medium-sized cities across the country, and other small and medium-sized cities to build a number of comprehensive pipe corridor projects according to local conditions. At the same time, the state encourages the development and construction of new roads, new urban districts, and underground pipe networks in various parks in accordance with the comprehensive pipe gallery model. In the past two years, the State Council, the Ministry of Housing and Urban-Rural D...
