Fraisthorpe

Onshore Project - Renewable Energy

CASE STUDY 13 920

Major design considerations: 1 Northern Powergrid set out strict connection requirements that needed to be met in order for the grid to accommodate the wind farm at 66kV. Powersystems design engineers used innovative design methods to meet

these requirements and allow the customer to start selling energy to the

Fraisthorpe Wind Farm electricity network.

Powersystems were responsible for the design, installation, testing and The first of these was to design infrastructure which ensured Northern commissioning of the electrical infrastructure Powergrid’s 66kV network would remain stable should faults occur on the associated with this project. This consisted of windfarm. This was important in order to prevent any unnecessary outages a 66kV grid connection which was adopted on the grid. The inclusion of a high impedance 66/33kV transformer tackled by Northern Powergrid (NPG) as well as the this problem without compromising the overall performance of the electrical works for nine 3.3MW V112 customer’s network. wind turbines. Project facts and figures: Fraisthorpe wind farm is a 29.7MW capacity  Number of turbines: 9 wind farm situated in the East Riding of  capacity: 3.3MW , . Granted full planning  permission in 2015, the Totalled installed capacity: 29.7MW generation site began generating clean  Length of 66kV underground cabling: 5km renewable energy in August 2016.  Length of onsite 33kV underground cabling: 18km

 Length of directional drilling under railway track: 100m The completed site produces enough electricity  33kV capacitor bank: 3.5 MVAr to power over 22,500 homes and stops over 48,000 tonnes of carbon dioxide gas from  66/33kV high impedance transformer: 36MVA entering the environment each year.  Powersystems have connected 24% of all onshore UK windfarms

The wind turbines were initially shipped to

Immingham Dock but safety concerns regarding the transportation of such large structures to site meant that they were unable to cross the Bridge. Instead, the 197-feet (60m) blades took a circuitous 100-mile journey to avoid this route and arrive safely at Fraisthrope.

The electrical work was undertaken in partnership with Jones Bros Civil Engineering on behalf of the client, BayWa r.e. GmbH.
