Abstract :
The application of a 12-pulse GTO voltage-source inverter (VSI) for tapping a small amount of HVDC power (10-15%) is investigated. The control strategy for a parallel multiterminal DC power system is briefly reviewed. A comparison of VSI and line-commutated inverter characteristics indicates that the GTO VSI offers some technical advantages for tapping applications. To confirm this, detailed digital time-domain simulations based on the Electromagnetic Transients Program for DC power systems are conducted. The simulated responses of the HVDC system embedding the GTO VSI tap under various planned and unplanned disturbances, demonstrate the technical feasibility of a small parallel tap using a GTO VSI. In addition, control strategies and protection requirements are identified for the proposed HVDC tap
