In this research work, the design and implementation of a 154-kV +/- 50-Mvar transmission static synchronous compensator (T-STATCOM) have been carried out primarily for the purposes of reactive power compensation and terminal voltage regulation and secondarily for power system stability. The implemented T-STATCOM consists of five 10.5-kV +/- 12-Mvar cascaded multilevel converter (CMC) modules operating in parallel. The power stage of each CMC is composed of five series-connected H-bridges (HBs) in each phas...
Optimization of location and number of lightning arresters in 420 kV substations in Turkish high voltage electricity system
Tulaz, Mert Ozan; Güven, Ali Nezih; Department of Electrical and Electronics Engineering (2014)
Insulation coordination is defined as the selection of the dielectric strength of equipment in relation to the voltages which can appear on the system for which the equipment is intended and taking into account the service environment and the characteristics of the available protective devices. In an insulation coordination study, the voltage levels of power system equipment are determined in order to ensure the protection of equipment against overvoltages. This proper design in terms of the insulation coor...
Design and implementation of a voltage source converter based statcom for reactive power compensation and harmonic filtering
Çetin, Alper; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2007)
In this thesis, design and implementation of a distribution-type, voltage source converter (VSC) based static synchronous compensator (D-STATCOM) having the simplest converter and coupling transformer topologies have been carried out. The VSC STATCOM is composed of a +/- 750 kVAr full-bridge VSC employing selective harmonic elimination technique, a low-pass input filter, and a /Y connected coupling transformer for connection to medium voltage bus. The power stage of VSC based STATCOM is composed of water-co...
Two-Level Quasi Multi-Pulse Voltage Source Converter Based Generalized Unified Power Flow Controller
VURAL, AHMET METE; Bayindir, K. C. (2011-09-01)
A multi voltage source converter (VSC) based flexible alternating current transmission system (FACTS) device, such as generalized unified power flow controller (GUPFC) has more control parameters than its successor unified power flow controller (UPFC). Owing to its multi VSC based configuration, GUPFC can concurrently control real/reactive power flows of two or more transmission lines and AC bus voltage magnitude. In this work, PSCAD/EMTDC model of GTO based GUPFC is developed consisting of two series-VSCs ...
Active clamped ZVS forward converter with soft-switched synchronous rectifier for maximum efficiency operation
Acik, A; Cadirci, I (1998-05-22)
An active-clamped, zero-voltage switched forward converter equipped with a soft-switched synchronous rectifier is designed and implemented for some low output voltage applications where maximized efficiency is of utmost importance. The converter efficiency is maximized due to soft-switching of the main, active clamp and the synchronous rectifier MOSFET switches. Experimental results are presented for a converter with a de input voltage of 48V, an output voltage of 5V and a de electronic load up to 10A. The ...
