The Voltage Source Converter (VSC) offers the possibility of full four quadrant operation and the total control active and reactive power with the minimal generation of harmonics with the SPWM technique. This paper presents the dq transformation of a VSC and its design of a vectorial control to regulate the DC voltage and reactive power in a rectifier station. Finally, the models and results are presented...
The basic function of VSCs is to convert the DC voltage stored in a capacitor into AC voltages or AC voltages into DC voltage. One of the advantages of the VSC is that this kind of electronic converters allow to control the active and reactive power flow with an ac-grid independently. This paper presents a short analysis of the characteristics and dynamic of VSC-HVDC, identification techniques to...
The paper discusses the operational domain of three phase voltage source converters (VSC) connected to an ac grid. The effects of the parameters (X/R ratio) of the conductors between the VSC and grid on the active and reactive power transfer are analyzed. The impacts on the control parameters, namely, the power angle and output voltage of VSC have been described. The study has revealed the active...
