dc.description.abstract This Thesis presents the results of a stability analysis of a novel Hybrid Modular Multilevel Voltage Source Converter topology suitable for long distance power transmission using High-Voltage DC. The small-signal modelling technique has been utilized in deriving a mathematical model for the converter configuration. The stability of the converter when the system is subjected to small disturbances are evaluated using Eigenvalue analysis techniques and by applying the stability criterion based on Lyapunov’s first method. The impact of the system strength of the connected ac network on the stability of the converter has been investigated with different Short-Circuit Ratios. Further the sensitivity of the converter stability to the changes in controller gains and measurement delays have been studied. The power carrying capability of this converter configuration has been evaluated for different modes of its operation. Converter ratings including the voltage limits and the maximum allowable current through the converter along with the impact of the network impedance have considered as constraints on power delivery in this study. en_US
