Fault Analysis and HVDC Power Transmission Using VSC Technique Integrated With Wind Turbine Grid System

Development of Electrical Power System with increase the Demand of an Energy create many Problem in Electrical Power System, like Sag and Swell in the Voltage level, also Swing in the Frequency value of Power System, and Instability in the Power System .In this paper study has been made to ensure uninterrupted power supply with increased reliability and performance of HVDC power supply by using VSC technique. Two converter stations are used in this technique, converter station 1 used for rectification of power which is generated by wind turbine and conventional generating stations and station 2 is used to rectify DC power into three phase HVAC power at the load end. The converter station of HVDC system use arrangement of power switches which work on the principle of VSC technique. Performance of transmission line has been analyzed on occurrence of three phase fault and after clearance of three phase fault.
