| Abstract |
In this paper, novel scrutiny of different types of bus-bar configurations is carried out to support the design of the system taking into account reliability aspects. The selection process of proper bus-bar configuration is dependent on several aspects which are: the degree of reliability, degree of security, cost, maintenance, operational flexibility, and safety as well as the selected fault DC grid protection strategy. The evaluation is carried out by evaluating the impact of different bus-bar topologies and DC fault clearing strategies on system overall reliability by considering equipment failures. In this assessment, switching and reconfiguration events are reflected to reveal realistic numerical results. At the end, a comprehensive comparison amongst different bus-bars is carried out from system point of view that highlights the level of reliability of various bas-bar configurations. |
