“…These results also show that CSC-STATCOM is more dissipative than its VSC counterpart as stated in some papers [2,3,6,10]. To quantify this point, power loss curve of a VSC-STATCOM in [27], which has the same technical specifications of prototype-II, is also plotted in Fig. 13.…”

ÖZStatik Senkron Kompanzatör (STATCOM) iletim hatlarında reaktif güç kompanzasyonu ve güç sistemi kararlılığının artırılması için kullanılmaktadır. STATCOM dağıtım hatlarında kullanılırsa dağıtım STATCOM (DSTATCOM) olarak isimlendirilmektedir. Özel bir güç aygıtı olan DSTATCOM, dağıtım sistemlerinde güç kalitesi sorunlarını çözmek için kullanılan ortak kuplaj noktasına şönt bağlı bir gerilim kaynaklı eviricidir. Evirici STATCOM ve DSTATCOM'un temel yapı birimidir. Literatürde önerilen ve gerçek uygulamalarda kullanılan birçok evirici yapıları mevcuttur. Bu makalede, bugüne kadar STATCOM ve DSTATCOM'da kullanılan evirici yapıları incelenmektedir. Evirici yapılarının avantaj ve dezavantajları ortaya konulmaktadır. Ayrıca literatürden birçok örnek verilmektedir.Anahtar kelimeler: STATCOM, DSTATCOM, reaktif güç kompanzasyonu, güç kalitesi, eviricilerThe inverter structures used in dynamics compensation devices: STATCOM and DSTATCOM topologies ABSTRACT Static Synchronous Compensator (STATCOM) is used for to improve the stability of power system and reactive power compensation of transmission lines. When a STATCOM used in a distribution system it is called Distribution STATCOM (DSTATCOM). As a custom power device DSTATCOM is a shunt connected voltage source inverter to a common coupling point in the distribution system and is used for to improve the power quality problems. The main structural unit of STATCOM and DSTATCOM are inverters. Many inverter topologies are used in the application and a lot of proposed inverter structures are available in the literature. In this study the inverter structures and topologies that are used in STATCOM and DSTATCOM up to now are investigated. The advantages and disadvantages of the inverter structures are presented. Also a lot of examples from the literature have been given. *

“…These techniques include Selective Harmonic Elimination (SHE) which uses precomputed firing angles to modulate the H-bridges [5], [6], and Phase-Shifted Carrier (PSC) PWM that uses comparisons with multiple triangular carrier waves to derive the appropriate switching signals [7], [8]. The complexity involved in solving the transcendental equations in SHE-PWM for a wide range of input conditions has limited the use of the technique.…”

Abstract-This paper further develops a Model Predictive Control (MPC) scheme which is able to exploit the large number of redundant switching states available in a multi-level H-bridge StatCom (H-StatCom). The new sections of the scheme provide optimised methods to trade off the harmonic performance with converter switching losses and capacitor voltage ripple. Varying the pulse placement within the modulation scheme and modifying the heuristic model of the voltage balancing characteristics allows the MPC scheme to achieve superior performance to that of the industry standard phase shifted carrier modulation technique. The effects of capacitor voltage ripple on the lifetime of the capacitors is also investigated. It is shown that the MPC scheme can reduce capacitor voltage ripple and increase capacitor lifetime. Simulation and experimental results are presented that confirm the correct operation of the control and modulation strategies.
