Objectives The key objectives for this feasibility study are to: Develop a Roadmap to evaluate the suitability of existing protection to cater for low system inertia/fault level conditions Protection modelling and validation; Establish the limitations of the existing policy to cater for future scenarios Identify alternative protection methodologies and their suitability for transmission systems under the various future scenarios; Develop a list of recommendations for optimising the existing protection system for adaptation to these challenges Production of reports addressing: Review of existing protection effectiveness. Development of a viable protection strategy suitable for all credible scenarios Implementation roadmap to optimise/migrate existing protection to a fit for purpose solution.
Abstract The protection principles and methodology which have been reliably used on the transmission systems since it was constructed last century have been very effective in providing a reliable and safe network. The increasing deployment of power electronic converter based technology such as wind turbines, HVDC links and photovoltaic to displace synchronous generation is fundamentally changing the nature of system faults and their detection using the traditional methods. There is the increasing possibility of new scenarios where the existing methods and policies may not be sufficiently reliable to detect and clear faults, thus increasing the likelihood of wider network stability issues and possible black-outs. As a consequence, the industry has recognised an increasing need to establish the effectiveness of existing protection strategies for the electricity transmission system in order to address the future energy scenarios being considered for the UK. The approach to this problem will involve researching the capability of National Grid’s existing protection solutions to detect and clear power system faults in networks which are dominated by the technology changes envisaged in the future scenarios. The assessment will develop power system models that can identify the technical performance of the existing protection strategy, using measured system data to validate the accuracy of the models.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
