Research on the Protection of Hybrid HVDC System

The traditional and conventional HVDC system has the advantages of lower installing cost and it is a mature state of the art, but it also has some drawbacks like huge reactive power absorption and commutation fault in the system. Similarly, HVDC based on VSC (Voltage Source Converter) is easily operational and flexible in control but it needs high cost for the installation that’s a drawback. A theoretical type of hybrid HVDC transmission scheme is presented in this manuscript after the combination of above-mentioned advantages of two HVDC systems. In this proposed scheme two control techniques are merged like PCC (Phase Control Converter) at sending terminal and VSC at receiving terminal of HVDC transmission system. Furthermore, the stability and steadily operation of the proposed system are verified by generating single phase to ground fault or short circuit fault in all phases. After getting the simulation results, it is observed that proposed hybrid HVDC system is capable of restoring the system rapidly by minimizing the effect of these faults.
