1. Closed-loop control and data- recording of a modular-multilevel converter (MMC)
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Modular multilevel converters (MMCs) are the preferred converter solution in flexible ac transmission systems (FACTS) and high-voltage direct current (HVDC) applications. This is due to the high quality of the voltage and current signals, lower overall losses, and fewer problems with switching-related EMI. READ MORE

3. Control Strategies for VSC-HVDC links in Weak AC Systems
University essay from Uppsala universitet/Avdelningen för systemteknikAbstract : In this master thesis control systems for a voltage-source converter HVDC connected to weak ac networks are investigated. HVDC stands for high voltage direct current and is a way to transfer power in the electrical power system. READ MORE

4. Detection and location of HVDC commutation faults from PMU data
University essay from Lunds universitet/Industriell elektroteknik och automationAbstract : Commutation Failures in LCC HVDC converters is a topic that is normally addressed from the component perspective, looking at converters’ internal signals. How these commutation failures affect the outer AC network is not deeply understood yet. READ MORE

5. A New Cell Bypass Arrangement and Control for Modular Multilevel Converters based on Thyristor Forced Commutation Circuit
University essay from KTH/Skolan för elektro- och systemteknik (EES)Abstract : HVDC transmission lines are a competitive and in some cases are proven to bea superior choice compared to AC transmission applications. Suitable convertershave been developed for that matter where Modulär Multilevel Converters (MMC)are highly preferred due to their low losses, no filtering requirementsand direct andfast control of AC and DC side.
