摘要

It is of fundamental interest to avoid faults in a DC grid due to the severely of these events. However, the faults are unavoidable, so in a fault case is necessary to act fast.The protection in a DC grid comprises a key component, the HVDC breaker. For this reason in this thesis, a simulation is programmed in order to be able to study the HVDC breaker operation, distinguishing between normal and fault operation. Matlab is the program used in this work, and an initial simulation is tested firstly to choose which method is the most appropriate.Once the circuit behaviour is studied, some tactics to improve the performance of the system are proposed, focusing on thermal losses.The principal results (current waveforms and energy dissipation) show that introducing some modifications into the system like using more IGBTs in parallel or changing the inductance values, it is possible to get a feasible DC breaker.To sum up, this report will present one tool being able to simulate different configurations and to study the results, besides some suggestions how to make the system more efficient.
