This paper presents the analysis and evaluates different control strategies of shunt active power filters which are used to reduce harmonic distortion created by an industrial paper factory. The model of the whole system has been carried out by Matlab/Simulink. In order to investigate the accuracy of the simulated model, harmonic analysis of simulation results has been compared with measurements from the electrical networks of a Paper Industrial Factory using harmonic analyzer. The consistency of simulation and measured results proves the accuracy of the system modeling. It also proves the validity of using Shunt Active Power Filters to reduce the harmonic distortion in the factory network. Four different control techniques, namely Unit Vector Template Generation, Instantaneous Active and Reactive theory, Synchronous Reference Frame theory and a proposed control strategy that combines the Synchronous Reference Frame and the Unit Vector Template Generation theories, have been studied. Results of each technique were satisfactory and meet the IEEE-519 Standard, However, when the source voltage is distorted the compensation capability for some control strategies is not equal.

Abstract. Active power filters (APF) are an important research domain, since several years ago. However the industrial use of APF is almost inexistent due to their high acquisition cost and to the absence of widely accepted criteria for usefulness. In most situations, where APF would be adopted, the plant management prefers a passive filter solution, considering simplicity, cost and rudeness. Consequently, power filtering is good for the mains network but presents a limited interest for the plant manager. Power quality in the user plant must be the main objective of active filters, instead of the suppression of harmonic content in the mains currents. This one must be a secondary objective, also achieved, but less important for the plant management, unless the contract with the power company obliges the reduction of current harmonic distortion. This approach is required to obtain the economic viability of active power filters. Consequently, the main economic objective of power filtering must be the power quality in the user plant. The power quality parameters can be evaluated as factors of cost in the design of active power filters. Another concern on the design and use of active power filters is the problem of the radio frequency conducted noise induced in the mains network. The hard switching technology, for bridge power converters, has been replaced, in our design of APF, by soft-switching technology. This paper presents a new design approach of APF based on the association of full-bridge hf soft-switching DC-DC converter with 6 cycloconverters (integral cycle control).

“…The research on Sliding-Mode Control in application to the PWM rectifiers is described in [12]. The principles of Sliding-Mode Control have also been applied to design of the control systems for the active power filters [13], [14] that power circuits refer to the topology of the typical three-phase two-level PWM rectifiers. Since the Sliding-Mode Control approach has no fixed switching frequency its application to provide the PWM pattern for the power converters may result in higher level of the switching power losses.…”

This paper presents a control method which combines sliding mode approach of direct power control and operates with constant switching frequency. This novel scheme Sliding Mode Constant Switching Frequency Direct Power Control (SM-CSF-DPC) employs a nonlinear sliding mode control (SMC) approach to directly calculate the required converter's control voltage. The constant switching frequency (CSF) is achieved by using space vector modulation (SVM). In this novel scheme, the extra current control loops are eliminated, which simplifies the system design and enhances the transient performance. The improved strategy is tested on a simulation model of a two level VSC and compared with the conventional switching table direct power control (ST-DPC) strategy. The proposed SM-CSF-DPC methods have very good results both in steady-state and transients. It is shown that the proposed DPC exhibits several features, such as a simple algorithm, constant switching frequency, robust to power step change, step change of referenced DC voltage and is capable of providing enhanced transient performance in case of line voltage sags.
