| Abstract | ||
| The main purpose of this paper is to improve the power quality in H.V transmission system when line is loaded, by producing solutions to voltage variations problems during load varying. The solution method employs the reactive power control by compensation techniques as the basis of voltage regulation to improve the power quality. Dynamic compensation is used to verify this purpose using FACTS technologies by introducing a circuit model of a SVC with multi level of switching capacitor bank as a source of VARs and one stage of inductor as aVAR absorber. The adopted technique here is to measure of the reactive power demand required to keep the bus voltage at its rated value and then the SVC will compensate the needs of VARs in the system by controlling the firing angle of the thyristors. The ability of VARs generation in the suggested model is four times of VARs absorption. | ||
