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

Er. Vivek Mishra, Dr. Surya Prakash, Er. Sudhanshu Tripathi

This paper deals with VSC based HVDC power transmission system. To increase the reliability of overall performance of the system. Use of Voltage source conversion makes system more comfortable to use for multi terminal and also for multi frequency system as per requirement of the load. Another technique is current source converter but these techniques have certain limitations as fixed frequency application and use of only two terminals for DC power transmission. This paper has also application of DFIG at the source end. By DFIG generation of active and reactive power can be control according to the requirement of load. Thus generating station has no need to change pressure of steam turbine as well as DC exciter setting. Thus controlling of DFIG and VSC is based on Direct and quadeture axis values of transmission line with PI controller
