Location Optimization of Newly Added Cable Considering Cluster Operation Temperature

Aiming at the location selection of new shunt cables in the process of urban network transformation, this paper first analyzes the preconditions of this problem, and provides a matrix idea for the engineering design scheme in the way of arrangement and combination; Secondly, based on the analysis of cable thermal resistance characteristics, the operating temperature of cable cluster is calculated by comprehensively considering the factors such as environment and load; Finally, the new cable location optimization model is established, and the data structure of the traditional particle swarm optimization algorithm is improved to adapt to the solution of large-scale problems. The calculation example adopts the new shunt cable under the 3×4 pipe laying mode, and the analysis verifies the rationality of the proposed optimization model and the effectiveness of the improved algorithm.
