A new harmonic distortion measurement algorithm for power quality evaluation and compensation

A new algorithm is proposed to measure the harmonic distortion without calculating individual harmonic components. This feature can greatly reduce the computational burden on many harmonic detection methods when it comes to power quality evaluation. In addition, the proposed algorithm can also facilitate power quality compensation such as shunt active filter control or active front-end coordination. Therefore, the proposed harmonic distortion measurement algorithm can provide a flexible and economical solution for many power quality problems. Simulation results verify the performance of the proposed algorithm.
