Abstract :
When grid voltage is nonsinusoidal, the detection current based on the instantaneous reactive power theory has error. After analyzing the current detection error, a improved n current detection algorithm based on the instantaneous reactive power theory is proposed. The detection current is accurate by the improved current detection algorithm, and the complexity of the algorithm is no significant increase.
