Research and EMTP Simulation of a New Control Strategy for Active Power Filter

A new control strategy of voltage source active power filter is presented in this paper. The control strategy is based on DC voltage control and reactive current feedback control, which directly controls output current and avoids complex computation of active and reactive power. The simulation results of EMTP-Scope view show that the new control strategy of the voltage source active power filter can effectively compensate the harmonic current and reactive current.

Analysis, design and simulation of three-phase active power filter with series capacitor topology for current harmonic compensation

The proposed system consists of an LC passive filter connected in series with three-phase active power filter. The passive filter is tuned to 13th order harmonic frequency. Major portion of harmonic current generated by nonlinear load is absorbs by passive filter, and active filter is used to improve filtering performance of the system by providing compensation for host of other higher order harmonics. Requirement of dc-link voltage of the active filter is less in the presented scheme as compared to that of standard voltage source active power filter without any other passive filtering component. This resulted in significant reduction in cost and power rating of active power filter. Analysis and design of various components of active filter are presented. Simulation analysis is carried out using instantaneous active-reactive power (P-Q) theory. Simulation results verify circuit configuration and filtering performance of the proposed topology. This system can be an attractive solution for effective harmonic filtering.

A new approach to control by model of a voltage source GTO active power filter

Harmonics generated by high power conventional AC/DC converters have become a serious problem for the AC mains as they can only be removed by using bulky passive filters. However, the remarkable progress made by power electronic devices in recent years makes it possible to concieve the self-adaptable harmonic suppressor called active power filter. In this paper we described a new approach of PWM control based on a modelisation of the active power filter decoupling reactor. The system under consideration is composed of a voltage source active power filter and a SCR rectifier bridge supplying an inductive load. The rectifier generates harmonic currents. The active power filter should detect and compensate them in order to approach the sinewave current in the mains. The harmonic current reference is calculated according to the method based on the calculation of the instantaneous power described by Akagi, Nabae and Atoh (1986). The GTOs are controlled by using the space vector method. Each GTO will switch one time per sampling period of 670 μs. This control has a good aptitude to minimize undesirable harmonic currents. In order to take into account of the delay time corresponding to the calculation time of the microprocessor a prediction of the current references is used. The whole system described above is studied in this paper. The modeling and numerical simulation using the specified open loop control are considered. The reliability of the system with respect to the variation of the system parameters is investigated.
