This paper describes the solution of power quality problems arising from 12-pulse smelter converters in ETI Aluminium Works. The design work is based on practical data collected in the field as well as on the results of detailed simulation studies obtained by EMTDC/PSCAD, SPICE and MATLAB. Main design objective is to meet both present regulations and harmonic standards by using robust, reliable and cost effective systems with a long life expectancy. The shunt-connected passive reactive power compensation system is composed of a damped 11(th) harmonic filter and a make-up filter tuned to 5(th) harmonic with optional damping resistor. Such a system exhibits nearly transient-free switching and series-resonance proof characteristics owing to damping resistors. A close correlation has been obtained between theoretical results and field data.

Advanced Active Power Filter to Improve Power Quality Gurguiatu, Gelu; Balanuta, Ciprian; Rosu, Emil; Munteanu, Toader; Dumitrescu, Mariana; Raducan, Elena (2011-09-10) This paper presents a three-phase Active Power Filter (APF) to improve grid power quality. Starting from indirect control strategy which was used only for three legs - three wires it is proposed in this paper to be used a bridge with three legs - four wire. The new control strategy it was named extended indirect control strategy. The extension consists in passing from the control of a three wire active power filter to the control of a four wire active power filter. The proposed active power filter can compe...
Field-Data-Based Modeling of Medium Frequency Induction Melting Furnaces for Power Quality Studies Yilmaz, Ilker; Salor, Ozgul; Ermiş, Muammer (2011-10-13) In this paper, the coreless, medium frequency induction melting furnace (IMF) system, has been represented by alternative field-data-based models, developed specifically for power quality studies. The IMF operation has been represented by a variable series RL circuit to model the fundamental components of electrical quantities, and a shunt-connected current source, to model the generated harmonics and interharmonics over a typical melting cycle. Both the sinusoidal coding method applied to the major harmoni...
Design and implementation of a voltage source converter based statcom for reactive power compensation and harmonic filtering Çetin, Alper; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2007) In this thesis, design and implementation of a distribution-type, voltage source converter (VSC) based static synchronous compensator (D-STATCOM) having the simplest converter and coupling transformer topologies have been carried out. The VSC STATCOM is composed of a +/- 750 kVAr full-bridge VSC employing selective harmonic elimination technique, a low-pass input filter, and a /Y connected coupling transformer for connection to medium voltage bus. The power stage of VSC based STATCOM is composed of water-co...
Control Strategies for Grid Connected PWM-VSI Systems Kantar, Emre; Usluer, S. Nadir; Hava, Ahmet Masum (2013-11-30) This paper evaluates the current control methods for three-phase voltage-source-inverters (VSIs) connected to the grid via LCL-filters. Current feedback methods from both line and converter sides are compared and theoretical analysis is stated. The analysis is based on the existence of a critical resonant frequency dividing the controlling frequency interval into two regions; namely low and high resonant frequency regions. The feedback types and damping methods are evaluated for both low and high resonant f...
