“…The most control algorithms of three-phase shunt active power filters are based on instantaneous PQ theory, synchronous detection method and using multilevel inverters. In [5,6], the Î 1 .cos(Φ) algorithm forces the supply current to be equal to the magnitude of the real component of fundamental load current, which is in same phase with the main sinusoidal supply voltage. This technique is applicable for three-phase voltage source inverters.…”

A new control strategy for active power filters is proposed, modeled and implemented in order to improve the power quality of a line commutated converter High voltage DC link. The ability of reactive power and harmonics reductions are generally met by using passive and active power filters. In this paper, modified active power filter with a modified harmonics pulse width modulation algorithm is used to minimize the source harmonics and force the AC supply current to be in the same phase with AC voltage source at both sending and receiving sides of a line commutated converter high voltage DC link. Therefore, it is considered as power factor corrector and harmonics eliminator with random variations in the load current. The modified harmonics pulse width modulation algorithm is applicable for active power filter based on a three-phase five-level and seven-level cascaded H-bridge voltage source inverter. Simulation results show that the suggested modified multilevel active power filters improve total harmonics distortion of both voltage and current with almost unity effective power factor at both AC sides of high voltage DC link. Therefore, modified active power filter is an effective tool for power quality improvement and preferable for line commutated converter high voltage DC link at different load conditions.

“…The existence of harmonics in power systems can cause some difficulties such as increasing power losses, decreasing maximum capacity of transmission lines, and interference with communication signals [1]. Numerous methods including the synchronous reference frame (SRF) and p-q-based method have been suggested to minimize these effects [2][3][4][5].…”

Increasing the application of power in electronic devices has increased the harmonics in power systems. Numerous methods like the synchronous reference frame (SRF) and the p-q-based method have been suggested to overcome the effects of these harmonics. The conventional SRF method provides acceptable results in harmonic compensation of high-order harmonics (higher than the fourth order), but the transient response time will be drastically increased in the presence of low-order harmonics due to the existence of a conventional low-pass filter. Furthermore, if the load terminal voltages are distorted, then the conventional SRF method will become unable to implement load current compensation. This research has used wavelet transform to overcome these difficulties. The proposed method is not only faster than conventional SRF, but it can also compensate the load currents if the load terminal voltages are also distorted. The simulation and experimental results are performed using MATLAB/Simulink and digital signal processor TMS320F28335 to verify the proposed method.

“…On the other hand, the time domain methods require less calculations and are widely Paper: ASAT-16-009-EP 3 followed for computing the reference current. The time-domain methods include, instantaneous reactive power theory p-q method [1 and 7-11], Synchronous Reference Frame (SRF) [12,13], Direct Testing and Calculating Method (DTCM) and Notch Filtering.

The increasing growth in the use of electronic equipment in recent years has resulted in a greater need to ensure that the line current harmonic content of any equipment connected to the ac mains is limited to meet regulatory standards. Shunt Active Power Filters (SAPF) are used to compensate both harmonic and reactive current component for the power supplies. It also improves the power quality and power factor on power utility. In this paper, Application of Direct Testing and Calculating Method (DTCM) in Shunt Active filters is proposed to estimate reference current signal, and apply hysteresis control to generate gate pulses. The results of simulation study of control scheme presented in this paper is found quite satisfactory for eliminate harmonics and reactive power components from utility, successful in meeting the IEEE 519 recommended harmonic standard limits.
