This paper presents a recently developed simulation software tool for ac predictive and mitigation techniques for pipeline networks influenced by high-voltage (HV) power lines. The software can deal with any configuration (no limitation on number of pipes, transmission lines, bonds, groundings, coating, and soil resistivity) and is very user friendly and robust since a general applicable algorithm is used to calculate the induced electromagnetic force (EMF), eliminating the need for a subdivision of the pipelines in sections parallel or not to the transmission line(s). With the calculated values for the EMF, the induced voltages and currents are then obtained by solving the well-known transmission-line model using a numerical technique that allows to specify the pipeline parameters (diameter, coating, soil resistivity, ...) for each individual section of the pipeline. In this paper, simulation results will be presented and compared with available theoretical test cases. It will be demonstrated that the calculated values for the induced EMF and the induced voltage and current are in perfect agreement with these theoretical test cases. In addition, it will be proven that commonly used formulas for the induced EMF need to be handled with care, especially when the distance between the transmission line and the pipeline becomes bigger.
