Objectives The objective of this project is determine the exact nature of the problem for both LCC and VSC interconnectors, and the mitigation measures required. Review of specifications related to cable interference issues. Determination of the exact problem as related to LCC and VSC systems in their most common topography. Development of the parameters that need to be collected to completely investigate the problem. Discuss and review mitigation measures and the options available pre, during and post-construction. Development of a mechanism/process suitable for route selection. Discuss mathematical and computer modelling techniques and how these can be utilised & developed. Review measurement techniques and equipment suitable for measuring harmonic currents and induced current.
Abstract HVDC cables installed adjacent to telecommunication lines and other assets can sometimes induce voltages which affect the functionality of these assets. The problem manifests in the telecoms line as a high noise level, making effective communication impossible. The problem National Grid faces, is that HVDC transmission links are crucial to the operation of the future, low carbon, transmission network, and interactions with other utility assets should be taken into consideration when installing, or solutions for mitigation should be found. Research The method proposed for this work is a desk based study involving a review of current standards related to cable interference issues, development of parameters needed to be collected for the problem to be investigated completely, discuss and review mitigation measures available pre, during and post construction and mathematical & computer modelling of the situations.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
