Steady State and Fault Analysis in Hvdc Transmission Network Based on Hybrid Cascaded Multilevel Vsc

The evolution of high-voltage fully controlled semiconductor technology has significant impact on efficient management of electrical grids. This paper proposes a high-voltage DC (HVDC) transmission systems based on a hybrid multilevel voltage source converter (VSC) with ac-side cascaded H-bridge cells. It deals with the control of Multilevel VSCHVDC, the… CONTINUE READING
