Analysis of Parameters Affecting the Capacitive Interference between Pipelines and Power Overhead Line Using Genetic Algorithms

Abstract

The proximity to high voltage power lines and gas pipelines is sometimes unavoidable for space reasons density of the soil. These pipelines are subject to electrical interference generated by power lines under normal and fault conditions. Due to this interference, AC voltages and currents can be induced on the aerial metallic pipeline, which may present a risk of electric shock to the operator; also threaten the integrity of the pipeline equipment. This paper aims to examine the capacitive coupling and the various factors affecting the level of this coupling, using a combination of charge simulation method and genetic algorithms (GAs) for the optimal position and number of fictitious charges used in CSM. The simulation results are compared with those obtained from the impedance matrix, a good agreement has been obtained.
