Wind Turbine Performance: Consideration the Execution of Power Performance Verification

Wind turbines operate at design performance to ensure project financial efficiency, and fairness in the Turbine Supply Agreement and achieve project commitments related to operating permits. Proving turbine performance is only possible through power performance testing, with a complex and rigorous process that complies with IEC standards. This paper evaluates possible impacts on turbine operating efficiency by analyzing data collected through the SCADA system. Due to the complicated implementation process, timing, and cost, the goal of the work is to provide more useful information to make an effective decision to implement a power performance verification. The paper is especially useful for the practical application of turbine performance analysis for the first stage of operation. Even during turbine commissioning, a turnkey contract is obligated to prove the turbine is working properly before taking over certificate and transferring the risk to the project.
