Breeze E-book: Lifetime Analysis of a Wind Turbine Component

Fredrik Larsson wrote this on June 16

This free e-book investigates how to use physics-based models and general OEM documentation to estimate the remaining lifetime of a wind turbine component. The main findings in this e-book can be broken down into two parts: the lifetime estimation of a wind turbines main bearing using measurement data and physics based models and the information available to wind farm owners in OEM design documentation to make internal component lifetime calculations using physics based models.

Free E-book: Quantifying Change in Power Performance using SCADA Data

Fredrik Larsson wrote this on June 29

This final e-book of the 3-part series focuses on measuring change in power performance. There is a brief review of the Power Curve, Annual Energy Production and common methods of measuring the absolute level of power performance. The alternatives for measuring change in power performance for a specific site are narrowed down. An in-depth case study is performed, presenting the methodology and results of the Side-by-Side Testing method. Using only SCADA data for the analysis, the effect of a blade add-on upgrade is evaluated. The analysis is based on a relative power relation between a test and reference wind turbine.

Last Year in Wind Energy Visualized

Fredrik Larsson wrote this on February 12

A new year has just begun and with that comes some new exciting figures over last year's development in wind energy. Our friends at the Global Wind Energy Council just released wind energy statistics for 2014 and we have of course updated our beloved Evolution of Wind Power map accordingly. It is safe to say that a lot has happened in the last 12 months.

Four Steps for Effective Asset Management of Wind Turbines

Jonas Corné wrote this on April 7

During the operational phase of a wind farm a great deal of things happen both inside and around the wind turbines that affect the performance and availability. All wind turbines are equipped with sensors that continuously feed the wind farm SCADA system with data.

Learned Power Curve & Nacelle Anemometry To Calculate Lost Production From Wind Turbines

Jonas Corné wrote this on March 28

Wind power turbines convert wind into energy. In order to know how well and effective that conversion is, it is of utmost importance to really understand wind conditions at the site not only during project development but also during the operational phase of the turbines.
