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 prov...

摘要:Beside the future need for offshore HVDC grids also the need for future onshore HVDC grids are currently extensively discussed. The requirements for HVDC substations as well as for HVDC connections for onshore and offshore applications differ a lot. This paper highlights the requ...

摘要:Up to date numerous HVDC projects have been realized all over the world. But all of them are point to point transmission lines or non meshed multi terminal HVDC systems. To guarantee redundancy and hence security of supply and system stability, a meshed HVDC grid (MTDC) is necess...

摘要:As the value of additional functionality of any new power technology is very case dependent, it is not possible to make general comments on the economics of VSC HVDC applications for bulk power transmission without considering alternatives. Therefore, the paper presents a methodo...

摘要:Any network expansion demands intensive planning studies and redesign of control and protection systems in order to maintain a reliable, system behaviour. Applying a control architecture, which enables the operation of a controlled transmission path without affecting the rest of ...

摘要:Besides the classical reasons for power quality problems, a growing share of power generated by renewable energy sources, together with a reduction of redundancies in lines and substations, have a negative impact on the power quality in the medium voltage (MV) and the low voltage...
