Key steps for wind turbine power performance testing

When should I carry out power performance tests?

Power performance testing is carried out to determine the economic value of a wind project and to ensure that projects are performing to expectations. Performance testing allows investors to identify project underperformance, ensure that projects are generating the expected return on investment, and manage investment risk.

By plotting the power generated against the wind speed, the power curve compares actual on-site results to the warranted power curve in order to identify any deviations or anomalies, which are then analyzed to pinpoint the root cause. The OEM will often recommend actions for improving performance, such as adding vortex generators, adjusting control parameters, or increasing the rated power to maximize the annual energy production and potential revenue of a wind farm.
