Project Title: FAULT ANALYSIS IN HVDC TRANSMISSION NETWORK BASED ON HYBRID CASC ADEDMULTILEVEL VSC
The development of high-voltage completely handled semiconductor technology has effect that is efficient that is significant management of electrical grids. This project proposes a high-voltage DC (HVDC) transmission systems in accordance with a hybrid multilevel voltage source converter (VSC) with ac-side h-bridge that is cascaded. It addresses the control of Multilevel VSCHVDC, making use of VSC-HVDC in a community that is large a transmission system that is bipolar. The aim of the task that is ongoing to evaluate the performance of the VSC-HVDC with ac-side h-bridge that is cascaded during DC pole to pole fault. A control system is developed combining an modulator that is capacitor that is internal balancing controller, an intermediate current controller in addition to an outer active and controller that is power is reactive. The control strategy PI that is considering and are examined and simulated in MATLAB / SIMULINK.
