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 and AN connected MV/1 kV coupling transformer. At the medium-voltage side of D-STATCOM, line current harmonics are minimized to comply with IEEE Std. 519-1992 for the weakest supply conditions by applying 8-angle TLN2 elimination technique. This makes necessary switching the water-cooled high voltage (HV) IGBT modules at 850 Hz, thus eliminating 5(th), 7(th), 11(th), 13(th), 17(th), 19(th), 23(rd) and 25(th) voltage harmonics at the input of VSC. By carefully designing the laminated bus system, and selecting minimum stray inductance de link capacitors directly mountable on the laminated bus, stray inductance of commutation path is brought to a nearly absolute minimum of 60 nH, thus maximizing the utilization of wire bond, single-side cooled HV IGBTs, and eliminating the need to RCD clamping snubbers, The performance of SHEM together phase-shift-angle control has been tested in the field on a 0-1780 kVAr capacitive, 6.3 kV VSC based D-STATCOM (-750/+900 kVAr VSC) prototype. Field test results show that SHEM together with phase-shift-angle control leads to optimum switching frequency, and device utilization for HV IGBTs and high system performance at the expense of slower response as compared to other known control techniques.

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 mining excavators by using a new-generation STATCOM Bilgin, Hazim Faruk; Ermiş, Muammer; Kose, K. Nadir; Cadirci, Isik; Acik, Adnan; Demirci, Turan; Terciyanli, Alper; Kocak, Cetin; Yorukoglu, Mustafa (2007-01-01) 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 integr...
Current source converter based STATCOM: Operating principles, design and field performance Bilgin, H.

In the paper, the relationship between the reactive power and the control variables is obtained, harmonic minimization techniques applicable to CSC are investigated, and then Selective Harmonic Elimination Technique is applied for the eliminatio...
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...
