Active Filter Energy Storage Requirements for Non-periodic Current Compensation

Application of Compensators for Non-Periodic Currents

Based on a new definition of non-active current/power, this paper presents the application of a parallel active filter for the compensation of non-periodic currents. Analysis of the compensation characteristics required for a variety of non-periodic currents such as those associated with arc furnaces is presented. In addition, the corresponding current rating and energy storage requirements of ...

Compensation Strategies for Shunt Active Power Filter in Single- and Three-Phase Systems: Different Formulation, Comparison and Evaluation

A New Strategy for Simultaneous Compensation of Instantaneous Reactive Power and Harmonics of Non-Linear Loads (RESEARCH NOTE)

This paper presents a new control method for simultaneous compensation of instantaneous reactive power and current harmonics by parallel active filters (PAFs). Reference compensating currents of PAF are calculated using the subtraction of instantaneous power from its average value. In this way, it is possible omitting high/low pass filter(s) from the control circuit of PAF, which usually result...

Acknowledgement – We would like to thank the U

This paper presents a new definition of non-active current, which is valid for single-phase and polyphase systems as well as for periodic and non-periodic waveforms. The definition is applied to a shunt compensation system, and different cases of non-periodic current compensation are studied. A variety of compensation characteristics of non-periodic currents and the rating requirements for the ...
