Offshore Wind Energy Webinar – CIGRE UK Events Webinar
02 October 2020
A JOINT WEBINAR ORGANISED BY THE CIGRE UK NGN & THE CIGRE DENMARK NGN.
Friday 2nd October 2020, 14:00-15:30 (BST).
CIGRE NGN UK and CIGRE NGN DK would like to provide a platform for recent research results and system operations experience related to the rapid transformation and challenges imposed on networks and markets by increased amounts of offshore wind energy.
Register to hear our Head of Power Systems Technologies Dr. Steven Blair, discuss the topic of Demonstration of integrated protection and condition monitoring for offshore wind using passive distributed sensing.
A key challenge for offshore wind generation is providing effective, granular monitoring of the assets to improve maintenance scheduling and drive down the associated costs. This presentation will describe a commercial product demonstrator for array cable protection, fault identification, and failure prognostics that has been deployed on the 7 MW Levenmouth demonstration turbine. The system automates the response to cable faults, reducing outage times and operational cost by identifying and isolating faulted cables while allowing others in the array to stay in production. It also collects detailed electrical power quality and mechanical monitoring information (such as cable joint temperature) – at every turbine in an array. This enables clear and granular visualisation of asset performance, and predictive maintenance insights for long term asset management. The sensing technology is entirely passive, so the cost, size, and weight of instrumentation is substantially reduced by eliminating the need for power supplies, transformers, copper wiring, data networks, or GPS clock access at every measurement location.
