Post-construction production assessment of wind farms
| 2016:297 | Johannes Lindvall, Johan Hansson, Ove Undheim
Focus in this report is on Developing methods for long-term adjustment of operational production data and Developing methods for estimation of losses using the potential energy production during periods when the turbine is in a non-full performance state.
Full performance is defined as “The WTG is operative and generating according to design specifications with no technical restrictions or limitations which affect generation”. A post-construction production assessment is especially valuable in refinancing and sales processes. But a post-construction annual energy production (AEP) estimation can also be used to update the long‑term internal budget for the wind farm. The methods developed to estimate the losses can also be used in the daily monitoring of the wind farm performance.
