Abstract

The BIL portal supports BIL operators of high voltage and extra high voltage lines (TSOs) in the secure identification of potentially affected pipelines. By means of span analysis, approximations with buried pipelines and lines can be identified application-specific, electromagnetic interference issues can be clearly addressed, and route planning or grid expansion can be significantly accelerated. The transmission of electricity on the north-south routes can partly be increased by increasing the capacity of the existing high-voltage lines, thus enabling the rapid availability of urgently needed capacities in southern Germany. To this end, the TSO requires the relevant pipeline operators between its mast sites, whose pipelines are exposed to inductive interactions.

According to current regulations Codes of Conduct of the industry associations, communication and coordination between the participants is required here. The first step in the identification process is noticeably faster because the BIL portal has created a special query classification that allows the TSO to access the areas of responsibility of the pipeline network operators analytically and make reporting available to all operators. This reporting is carried out in accordance with the span field, which means that between the mast sites an area with 400 m extension on both sides of the central axis of the mast locations is intersected as a request area with the areas of responsibility of the operators. This first identification result reliably provides the TSO with the operator names per span and informs the pipe network operator of the analysis carried out. The final communication takes place via the BIL portal in both directions.
