This paper describes the solution of power quality problems arising from 12-pulse smelter converters in the ETI Aluminum Works, Seydisehir, Turkey. 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. The 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 11th harmonic filter and a make-up filter tuned to the 5th 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.

State-Estimation-Based Determination of Harmonic Current Contributions of Iron and Steel Plants Supplied from PCC
Sezgin, Erhan; Göl, Murat; Salor, Ozgul (Institute of Electrical and Electronics Engineers (IEEE), 2016-05-01)
In this paper, a state-estimation-based method is proposed to determine harmonic current contributions of iron and steel (I&S) plants supplied from a point of common coupling (PCC). Due to highly nonlinear nature of the I&S plant operation, accurate estimation of harmonic contributions of the individual plants is essential. In the proposed method, the nonlinear characteristics of the plants and the utility are modeled as harmonic current sources and the harmonic current contributions of loads are decoupled ...
Hydrometallurgical processing of nontronite type lateritic nickel ores by MHP process
Kose, C. H.; Topkaya, Yavuz Ali (Elsevier BV, 2011-04-01)
The research work presented in this paper determined the optimum conditions at which nickel and cobalt could be obtained at maximum efficiency from the column leach liquor of the lateritic nickel ore existing in Gordes region of Manisa in Turkey by performing effective hydrometallurgical methods. This column leach solution was initially neutralized and purified from its basic impurities by a two-stage iron removal process, nickel and cobalt were precipitated in the form of mixed hydroxide precipitate from t...
Self-excitation of induction motors compensated by permanently connected capacitors and recommendations for IEEE Std 141-1993
Ermiş, Muammer; Cadirci, I; Zenginobuz, G; Tezcan, H (Institute of Electrical and Electronics Engineers (IEEE), 2003-03-01)
Self-excitation of induction motors compensated by permanently connected capacitors is investigated in this paper. Theoretical analyses of self, excitation phenomenon are carried out by using some simplified equivalent circuits, and a hybrid mathematical model in ABC/dq axes, respectively, in steady state and transient state. An unusual operating condition about water pumping stations is reported, in which water within the pipeline may drive the motor in the reverse direction at speeds higher than synchrono...
Severity Estimation of Interturn Short Circuit Fault for PMSM
Qi, Yuan; Bostancı, Emine; Zafarani, Mohsen; Akin, Bilal (Institute of Electrical and Electronics Engineers (IEEE), 2019-09-01)
This paper presents a novel method to estimate the number of shorted turns in a permanent magnet synchronous machine (PMSM) following the detection of interturn short-circuit (ITSC) fault and its location. In this proposed method, PMSM is excited through a low sinusoidal voltage at standstill condition to obtain the winding resistance and synchronous inductance by current response. It is shown that the ITSC fault introduces variation in the current response, which can be used to calculate the number of shor...
