   A Novel Optimal Controller for Tracking of Reference Compensating Currents of Parallel Active Filter
By M. Tarafdar Haque, R. Fathi [View]
[Download]

Abstract: This paper proposes a new optimal feedback controller for tracking of reference compensating current of a parallel active filter (PAF). The new controller compensates the harmonics of current produced by non-linear loads. Also the proposed controller will compensate the load reactive power. This controller will generate the switching pattern of PAF by minimizing the objective function J that is the difference between actual and reference compensating currents. The mathematical model of PAF will be addressed in detail. Reference current is calculated by instantaneous positive sequence of load currents and utility voltages with PQ theory. Simulation results and theoretical details are presented to show the validity of proposed strategy.

   Implementation of a Digital Signal Processor-controlled Shunt Active Filter
By Leonardo Rodrigues Limongi, Marcelo Cabral Cavalcanti, Francisco de Assis dos Santos Neves, Gustavo Medeiros de Souza Azevedo [View]
[Download]

Abstract: This paper presents the implementation of an active filter configuration for harmonic compensation. The system can be controlled for current harmonics and reactive power compensations simultaneously by using a converter operating as active shunt filter. A synchronous reference frame based controller is compared to an instantaneous reactive power based controller. The synchronous reference frame method is chosen to control the converter due to the better performance when the supply voltage is distorted. A shunt active filter system has been designed and built to meet IEEE 519 recommended harmonic standards. Simulation demonstrates the good performance of the active filter configuration. Experimental results, corresponding to the operation of the digital signal processor-controlled shunt active filter are also presented.

   Inverse Action of Series Connected FACTS Devices During Voltage Collapse Phenomena
By Nemat Talebi, Javad Karamdel, Ali Farrokhi [View]
[Download]

Abstract: This paper focuses on detailed steady state models with emphasize on control modes of two Flexible AC Transmission System (FACTS) devices’ namely, Static series synchronous compensator (SSSC) and Thyristor Controlled Series Capacitor (TCSC), to study their effects on voltage collapse phenomena in power systems. Based on results at the point of collapse ‘ control loops strategies which could increase system loadability or increase loading level to voltage collapse point are determined. The IEEE 14 bus test system is used to illustrate the effects of FACTS devices control strategies on voltage collapse phenomena.

   The Generically Equal Harmonic Behavior of Three Phase PWM Voltage and Current Source Converters
By Michael Bierhoff, Friedrich W. Fuchs [View]
[Download]

Abstract: In this article the significant key quantities regarding harmonic generation on the AC as well as on the DC side of voltage and current source converters (VSC, CSC) are derived. Thereby generic equalities are elaborated. This work is considered a general remedy to the question of harmonic performance of a VSC compared to a CSC apart from the usual concerns such as semiconductor losses, installed semiconductor power or energy storage components lifetime.
