The main aim of this project is a fuzzy controlled LLC HVDC system with AC voltage and reactive power control. This paper has investigated and demonstrated the reactive power and voltage control capability of LCC HVDC system with controllable capacitors. The reactive power control and voltage control at the inverter side of the fuzzy controlled LCC HVDC system with controllable capacitors have been proposed and associated controllers have been implemented. In connection with the reactive power control or voltage control, active power control at the rectifier side is desirable and such a control has been adopted in this paper. This paper investigates the reactive power and AC voltage fuzzy control at the inverter side of the LCC HVDC system with controllable capacitors. The traditional PI controller in the AC voltage and reactive power control is replaced with fuzzy controller improving the response time of the controller and the converter. The modelling of the proposed fuzzy controlled HVDC system is done in MATLAB software with Sim-power-system toolbox generating graphs using GUI environment.
