This paper deals with the performance analysis of a two-level, 24-pulse voltage source converters (VSCs) for high voltage DC (HVDC) system for power quality improvement. A two level VSC is used to realize a 24-pulse converter with minimum switching loss by operating it at fundamental frequency switching (FFS). The performance of this converter is studied on various issues such as steady state operation,...
This paper presents an approach to control the power flow and regulate the DC voltage at the DC link of voltage source converter (VSC) based high voltage DC (HVDC) transmission system. Two identical converters used at both rectifier and inverter ends. The switching of the converter is carried out at fundamental frequency switching. The power flow between the two stations is controlled by controlling...
For stable operation of a power system reliable control of active & reactive power is necessary. Voltage source converter based HVDC system bears the advantages of being able to change the control strategy immediately with respect to the active and reactive power changes. In this paper a function based fuzzy control system is proposed for the control of active power, DC voltage at converter station...
