A Study on the Improved Harmonic Current Detecting Method Based on i_p—i_qCalculating Modes

Abstract:

With the development of power system, the rapid and accurate detection of harmonic and reactive currents is premise of reactive power compensation and harmonic suppression. With MATLAB software, a research on simulation of harmonic detection and improvement method based on instantaneous reactive power theory is carried out. The result indicates that the harmonic detection improvement method of ¡_P—¡_qbased on instantaneous reactive power theory have a faster response time and better real-time.
