Abstract:Harmonic distortion in power networks has greatly reduced power quality and this affects system stability. In order to mitigate this power quality issue, the shunt active power filter (SAPF) has been widely applied and it is proven to be the best solution to current harmonics. This paper evaluates the performance of the modified synchronous reference frame extraction (MSRF) algorithm with fuzzy logic controller (FLC) based current control pulse width modulation (PWM) inverter of three-phase three-wire SAPF to mitigate current harmonics. The proposed FLC is designed with a reduced amount of membership functions (MFs) and rules, and thus significantly reduces the computational time and memory size. Modeling and simulations of SAPF are carried out using MATLAB/Simulink R2012a with the power system toolbox under steady-state condition, and this is followed with hardware implementation using a TMS320F28335 digital signal processor (DSP), Specrum Digital Inc., Stafford, TX, USA. The results obtained demonstrate a good and satisfactory response to mitigate the harmonics in the system. The total harmonic distortion (THD) for the system has been reduced from 25.60% to 0.92% and 1.41% in the simulation study with and without FLC, respectively. Similarly for the experimental study, the SAPF can compensate for the three-phase load current by reducing THD to 5.07% and 7.4% with and without FLC, respectively.

The aim of this paper is an easier control method for an active filtering and energy recovery system for high power DC traction substations. This system converts the classical dc traction substation, with 6-pulse three-phase bridge rectifier, in an "active substation". The active substation allows both the braking energy recovery to the power grid and the compensation of current harmonics and reactive power of the current absorbed from the power grid. To achieve this goal an indirect current control method had been investigated and implemented both on a virtual system and on a scale experimental model.

“…Various authors have proposed several control approaches, which are appropriate for disrupted utility state 4,5 . Numerous current control structures have been suggested for the control of DSTATCOM, from which hysteresis current control (HCC) and linear control with pulse width modulation (PWM) are the most conventional controller in the literature 6‐8 . New and more complex control techniques such as fuzzy, sliding mode, adaptive and predictive controls have been implemented with progress of energetic and fast microprocessors.…”

In this paper, a novel Instantaneous Symmetrical Component Active Power theory with Finite Control State based Model Predictive Control (ISCAP‐FCS‐MPC) strategy is proposed for Distribution‐Static‐Compensator (DSTATCOM) to enhance the power quality in distribution system. Unlike conventional control schemes, the proposed method does not necessitate modulators for switching pulse creation and the discrete implementation of the system is offered to assess the forthcoming actions of the source currents for each of the eight achievable switching actions. These switching actions are generated with regard to turbulences raised in load as well as source sides. The proposed methodology is justified via MATLAB/Simulink environment and a relative analysis is realized through conventional Proportional Integral based Hysteresis Current Control (PI‐HCC) strategy. Further, an experimental investigation is accomplished with consideration of Real‐Time Digital Simulator (RTDS) incorporated with front end processor Xilinx spartan‐3 XC3S5000.
