Abstract

Evaluation of power quality (PQ) becomes an important issue for the grid integration of wind energy systems. To provide accurate estimation of grid situations, a calibration test platform is designed in this paper to assess the capability of commercial PQ instruments. In accordance with the latest International Electrotechnical Commission standards, the test power signals can be generated, and the standard PQ indices can be precisely obtained by designed autoregressive-model-based synchronization and voltage envelope extraction processes. In this way, the commercial PQ instruments can be conveniently calibrated to meet the measurement requirements during the continuous operation of wind turbine.
