The DC transmission has been very prized due the its lower costs relative to the AC transmission, mainly for long distances and with the useful of less cables to supply energy in relation at the HVAC (High Voltage Alternating Current). The FACTS devices (Flexible Alternating Current Transmission System) were designed to supply a better control and quality of transmitted energy, and can be connected at generator station or at load. These devices improve the stability and the capacity to supply voltage and power, being very useful to increase the transmission capacity of energy. The present work analyses the voltage, current, active e reactive power consumed by the converters, before and after the filters, using a capacitor banks, and after that, replacing the capacitor bank by a SVC (Static Var Compensator) in a Classical HVDC circuit. The analyzed circuit consists of a 60Hz, 500kV generation which transmits power for a 50Hz, 345kV station. Then, also analyses the current harmonic distortion elimination, common in the 12 pulses converter, and the reactive staff for reduced voltage and current and a 3-phase fault on the inverter AC side.
