Harmonic Detection Algorithm based on DQ Axis5
نویسنده
چکیده
The paper presents the DQ axis with Fourier analysis (DQF) algorithm to identify harmonic quantities for hybrid power filters. This algorithm is a combination of the advantages of DQ axis method and sliding window Fourier analysis (SWFA). This paper also presents the harmonic elimination by using the DQF algorithm for both three-phase balanced and unbalanced systems. The results show that the unbalanced system becomes a balanced condition with successfully reducing the quantity of system harmonic components after completely harmonic elimination by using the proposed algorithm. The results confirm that the DQF algorithm is flexible and suitable in terms of design for hybrid power filters. Key-Words: harmonic elimination, harmonic detection, hybrid power filter, DQ axis with Fourier

متن کاملCross Entropy-Based High-Impedance Fault Detection Algorithm for Distribution Networks
The low fault current of high-impedance faults (HIFs) is one of the main challenges for the protection of distribution networks. The inability of conventional overcurrent relays in detecting these faults results in electric arc continuity that it causes the fire hazard and electric shock and poses a serious threat to human life and network equipment. This paper presents an HIF detection algori...
متن کاملTorque Ripple Reduction of an Interior PM Synchronous Motor by Compensating Harmonic Currents based on Flux Linkage Harmonics
The back emf harmonics of a permanent magnet (PM) synchronous motor is a major source of torque ripple. For torque control applications including column fitted MDPS (motor driven power steering) systems, it is essential to reduce the mechanical vibrations due to torque ripples at low speeds. In this paper, a torque ripple reduction algorithm for interior PM synchronous motors is proposed. The h...
