“…Nowadays, more and more applications in the medium voltage (MV) range are emerging, with for example STATCOMs [3], railway supply with static frequency converters, e.g., three-phase 50 Hz to single-phase 16.7 Hz, [4], [5], drives [6], [7], onshore power supply [8], medium voltage dc (MVdc) transmission, for power levels up to 150 MW over 200 km and 50 kV dc [9], [10], etc. At their heart is a modular structure, with multiple branches (or chain-links) [11], that offer an increased level of performance compared to monolithic designs.…”

Abstract-Modular multilevel converters are increasingly being considered or used for various medium voltage applications. Multiple control methods have been proposed for the control of the direct to three-phase modular multilevel converter. They differ one from another in the way the capacitor voltage ripples are handled, i.e. either neglected, estimated, reconstructed by filtering or measured. This has implications on the performance level that can be obtained. This paper provides insights on the advantages and drawbacks of each control method, in inverter and rectifier mode, with a fair and thorough assessment supported by extensive simulations, with converter ratings that are realistic for medium voltage applications. Finally, this works highlights the impact of the higher dynamics for medium voltage dc applications compared to high voltage dc ones on the choice of the control method.

“…The flicker performance of the multilevel STATCOM is significantly higher compared to a conventional thyristorbased SVC, consisting of thyristor controlled reactors (TCR) and filter circuits. The flicker performance of these systems is usually limited to a maximum factor of 2 [2], which disqualified this technological option. The electrical performance of the multilevel STATCOM is depicted in Figure 9.…”

STATCOM technology has experienced a significant degree of market diffusion over the last years. This is largely due to the technological advancement of the modular multilevel converter topology. This paper presents the basic aspects of this topology and provides three case studies for existing multilevel STATCOM references that underline the advantages of this technology -namely: modularity, low interaction with the network through low generation of harmonics and less primary equipment resulting in a small footprint.

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. *
