AbstractHigh Voltage Direct Current Transmission (HVDC) with Voltage Source Converter (VSC) technology provides substantial technical and economical advantages for different applications compared to conventional HVDC transmission systems based on thyristor technology. This paper is focusing on the modeling and analysis of Three-Level Neutral Point Clamped (NPC-VSC) as it is one type of multi-level voltage source converter Diode-Clamped Circuit (DCC).This system is regard as light system based on HVDC transmission, of high power ratings (up to 600 MW). Application of the proposed technique is adopted and tested for Iraqi Super High Voltage Grid (400 kV), where the proposed model is simulated using MATLAB. The results show a good response of the control system for certain fault conditions considered to show the advantage of using such system.
