“…Firstly, the instantaneous distorted current I d is measured. Then, by a signal processing algorithm the harmonic currents are identified [46], [47]. These harmonic currents feed the current controller which should assure steady-state tracking.…”

Abstract-This work reviews the state-of-the-art in the field of harmonic resonance problems in Wind Power Plants (WPPs). Firstly, a generic WPP is modeled according to the equivalent circuits of its passive and active components. Main focus is put on modeling active components, i.e. the ones based on power converters. Subsequently, pros and cons of frequency and time domain analysis methods are outlined. The next sections are devoted to mitigation methods implemented in the power electronics converters. From the wind turbine perspective, different techniques to enhance the robustness of the controller are analyzed. Subsequently, the suitability for active damping of harmonics using STATCOM devices is assessed, with focus both on control techniques and power converter technologies.

“…This approach is popular due to its simplicity, reliability, efficiency and low cost [4], but at the expense of providing incomplete solutions particularly when compensating random frequency variations in the current, tuning and parallel resonant problems. In recent years, various active power filters (APF) configuration with their respective control strategies have been proposed and have been recognized as a viable solution to the problem created by harmonics [5][6][7]. Amongst the technique that have been developed are the extraction and the estimation approach.…”

“…Instantaneous reactive power theory (p-q theory), modified p-q theory [8][9][10], p-q-r theory [11,12], vectorial theory [13] and d-q theory [7,14,15] are the techniques that fall into the extraction technique. In many cases, d-q algorithm have been widely used to eliminated the harmonics due to its simplicity of control design relative to the rest [6].…”

-This paper presents a new technique of reference current generator based on Kalman filter (KF) estimator for three-phase shunt active power filter (APF). The stationary reference frame (d-q algorithm) is used to transform the load currents into DC component. The harmonics of load currents are extracted and the three-phase reference currents are generated using KF estimator. The work is simulated using Matlab/Simulink platform. To validate the simulation results, an experimental test-rig have been perform using real-time control dSPACE DS1104. In addition, hysteresis current control was used to generate the switching signal for the correction of the harmonics in the system. The nonlinear load were constructed with three-phase rectifier which connected in series with inductor and parallel with resistor and capacitor. The results shows that the new technique of shunt APF embedded with KF is proven to eliminate the harmonics created by the non-linear load with some improvement on the total harmonics distortion (THD).

“…These harmonic currents can lead to instability, voltage distortion and interference with electronic appliances. The active power filter (APF) is a viable solution for these problems [1]- [3]. APFs are connected in parallel with nonlinear loads and act as a controlled current source to compensate the harmonic and reactive currents.…”

The one cycle control (OCC) scheme for active power filters (APFs) has shown excellent harmonic suppression and implementation simplicity. However, its real world application is limited because the non-ideal supply voltage for APFs can influence its performance so that the source currents are still distorted after compensation. This paper proposes a modified one cycle control (MOCC) scheme to improve the performance of three-phase shunt APFs under non-ideal supply voltage conditions. In this paper a detailed mathematical derivation has been presented and the key control law of the MOCC has been developed for adaption to the non-ideal supply voltages, following the control philosophy of simplicity. A relatively simple sequence filter is introduced to extract the harmonic components of supply voltages. The modified scheme can be easily implemented. The proposed control strategy has excellent performance and a 5kVA APF hardware platform has been implemented to validate the feasibility and performance of the proposed strategy.
