This paper deals with the development and implementation of a current-source-converter-based static synchronous compensator (CSC-STATCOM) applied to the volt-ampere-reactive (VAR) compensation problem of coal mining excavators. It is composed of a +/- 750-kVAR full-bridge CSC with selective harmonic elimination, a low-pass input filter tuned to 200 Hz, and a Delta/Y-connected coupling transformer for connection to medium-voltage load bus. Each power semiconductor switch is composed of an asymmetrical integrated gate commutated thyristor (IGCT) connected in series with a reverse-blocking diode and switched at 500 Hz to eliminate 5th, 7th, 11th, and 13th current harmonics produced by the CSC. Operating principles, power stage, design of dc link, and input filter are also described in this paper. It has been verified by field tests that the developed STATCOM follows rapid fluctuations in nearly symmetrical lagging and leading VAR consumption of electric excavators, resulting in nearly unity power factor on monthly basis, and the harmonic current spectra in the lines of CSC-STATCOM at the point of common coupling comply with the IEEE Std. 519-1992.

VSC BASED D-STATCOM WITH SELECTIVE HARMONIC ELIMINATION Cetin, A.; Ermiş, Muammer (2007-09-27) This paper describes the design, implementation and performance of a medium-size distribution type static synchronous compensator (D-STATCOM) with the simplest 2-level, 3-leg VSC topology. Reactive power control is achieved by phase-shift-angle control, and voltage source converter (VSC) harmonics arc eliminated by selective harmonic elimination method (SHEM) technique. VSC has been designed at the highest low-voltage level of 1 kV, and connected to medium-voltage (MV) bus through a low-pass input filter an...
VSC-Based D-STATCOM With Selective Harmonic Elimination Cetin, Alper; Ermiş, Muammer (2009-05-01) This paper describes the design, implementation, and performance of a medium-size distribution-type static synchronous compensator (D-STATCOM) with the simplest two-level three-leg voltage-source converter (VSC) topology. Reactive-power control is achieved by phase-shift-angle control, and VSC harmonies are eliminated by selective harmonic elimination method (SHEM). VSC has been designed at the highest low-voltage level of 1 kV and connected to a medium-voltage (W) bus through a, low-pass input filter and D...
REACTIVE POWER COMPENSATION OF COAL CONVEYOR BELT DRIVES BY USING D-STATCOMs Cetin, A.; Bilgin, H. F.; Acik, A.; Deinirc, T.; Kose, K. N.; Terclyanli, A.; Gultekin, B.; Aksoy, N.; Mutluer, B.; Cardirci, I.; Ermiş, Muammer; Ongan, K.; Akinci, N. (2007-09-27) This paper discusses feasibility of conventional and fully static reactive power compensation techniques used in the solution of power quality problems of coal conveyor belt drives and also describes the features and field performance of the Distribution type Static Synchronous Compensator (D-STATCOM) prototypes in such applications. They are composed of 2-level, 3-leg Voltage/Current Source Converters (VSC/CSC), low-pass input filters and Delta / Y connected coupling transformers to allow their connection ...
Pseudo-steady state inflow performance relationship of reservoirs undergoing multiphase flow and different wellbore conditions Al-Rbeawi, Salam (Elsevier BV, 2019-08-01) This paper introduces an integrated approach for the inflow performance relationship of reservoirs that undergo multiphase flow conditions and drained by vertical wells with different wellbore conditions. The main objective is eliminating uncertainties that govern predicting reservoir performance by assuming single phase flow in the porous media. The proposed approach includes developing several models for multiphase flow conditions using PVT data and relative permeability curves. These models are assembled...
On-Line Application of SHEM by Particle Swarm Optimization to Grid-Connected, Three-Phase, Two-Level VSCs with Variable DC Link Voltage Guvengir, Umut; ÇADIRCI, IŞIK; Ermiş, Muammer (2018-08-01) This paper is devoted to an otablen-line application of the selective harmonic elimination method (SHEM) to three-phase, two-level, grid-connected voltage source converters (VSCs) by particle swarm optimization (PSO). In such systems, active power can be controlled by the phase shift angle, and reactive power by the modulation index, against variations in the direct current (DC) link voltage. Some selected, low-odd-order harmonic components in the line-to-neutral output voltage waveforms are eliminated by c...
