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...
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 ...
Performance Characteristics of the Reduced Common Mode Voltage Near State PWM Method
Un, E.; Hava, Ahmet Masum (2009-07-01)
The Near State PWM (NSPWM) method, which has low common mode voltage and low common mode current, is proposed for three-phase voltage source inverter drives. The method is described and its voltage linearity, output current ripple, DC bus current ripple, common mode voltage and output line-to-line pulse patterns are thoroughly studied and compared with classical PWM methods. The theory, simulation, and laboratory experiments illustrate that in the high modulation index operating range NSPWM has superior ove...
Design, implementation and engineering aspects of 12-pulse TCR based SVC systems for voltage regulation
Parlak, Deniz; Ermiş, Muammer; Mutluer, H. Bilge; Department of Electrical and Electronics Engineering (2014)
Thyristor controlled reactor (TCR) based static VAr compensator (SVC) systems has various types with unique characteristics. Considering power system requirements, suitable compensator type should be chosen. In this thesis work, 12-pulse TCR based voltage regulation type SVC system is analyzed, simulated and implemented. Principles of operation, strong and weak points are discussed. The developed system has been implemented in order to solve voltage regulation problem in Dhurma (Saudi Arabia). According to ...
