Abstract

Reactance modulation of power transmission lines has great effects on load voltage control and on the stability of power transmission. Steady state voltage control can be easily achieved with conventional control devices such as switchable capacitors and reactors, while transient voltage control requires faster and more effective means of control [1]. In this paper, the transient voltage control is achieved by modulation of the net reactance of the transmission line using Voltage Drop Compensator (VDC) through hysteresis switching of a dc current from Voltage Source Converter (VSC) to charge/discharge a capacitor in series with the line. Modulation of the capacitor voltage by dc current from VSC improves the voltage control of the load, reduces the voltage drop on the transmission line, and improves the stability of the power transfer [2-4]. High frequency switching of the capacitor through charging/discharging process ensures faster response to transients in the input voltage and prevents it from appearing in the load. Fast response to variation in the input supply is done by comparing the load voltage to a sinusoidal reference voltage every time this voltage deviates from a fixed hysteresis window. Under this method of capacitor voltage control, no control is exerted on the dc current from VSC which can reach hundred amperes. In this paper a dc current controller is introduced to limit the dc current from VSC to a any value desired or to any other value necessary to keep the load voltage sinusoidal.
