原始语种摘要: One of the most challenging aspects regarding realization of meshed HVDC systems are DC line faults. On the one hand new fault clearing equipment needs to be developed. On the other hand it is very important to define suitable fault detection methods. This is necessary since proven methods for AC grids cannot be applied in DC grids since they are too slow to cope with DC fault current phenomena. To clear DC faults it is important to have fast acting fault clearing but at least equally important to have very fast fault detection. For time critical and economical reasons it is also required to have a decentralized fault detection method. This paper describes basically DC fault current calculation, shows typical HVDC fault current characteristics and proposes an appropriate DC fault...
