Offshore Wind Energy Webinar
A Joint webinar organised by the CIGRE UK NGN & the CIGRE Denmark NGN
Friday 2nd October 2020 | Online Webinar | 14:00 – 15:00
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.
Topics
Demonstration of integrated protection and condition monitoring for offshore wind using passive distributed sensing | Steven Blair
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.
European HVDC and Offshore Wind | Dr Gen Li
Europe now has a total installed offshore wind capacity of 22,072 MW from 5,047 grid-connected wind turbines across 12 countries. The HVDC technology for offshore wind integration is becoming more mature. This presentation will give the state-of-the-art of HVDC and offshore wind technologies in EU countries. The driving forces, key technologies and challenges will be presented and discussed.
Offshore wind and HVDC technology- An Overview | Lorenzo Zeni
The presentation will give an overview of HVDC grid connection systems for offshore wind power evacuation. The presentation will touch upon the technology in general as well as the most interesting aspects and open questions regarding the integration of these technologies in the power system, including stability, ancillary services, etc. The presentation will be given from an offshore wind power developer’s perspective.
Introduction to Ørsted Offshore focussing on grid connection systems for offshore wind farms| Troels Stybe Sørensen
Ørsted Offshore is the largest offshore wind farm developer in the world. This presentation will give an overview of the development Ørsted has been through focussing on the development in scale and complexity of the grid connection systems.
