HVDC and HVAC systems at the same support structure are an important issue to increase the transmission capacity of a corridor. But due to the near vicinity of the different systems influences can occur. This paper describes the induced voltages on HVDC systems. These will be determined with a decoupled method for inductive and capacitive coupling of different tower structures to get a first impression...
This paper deals with the concept development and laboratory testing of an adaptive protection system for distribution networks with distributed energy resources. Adaptation of protection relay settings according to currently available short-circuit current at respective grid nodes, is one solution to cope with the challenges originating from distributed generation. The challenges in conventional...
This paper deals with the protection system in distribution networks with distributed generation. It describes the dynamic influences of synchronous generators on the direction determination of protection relays during network disturbances. Therefore the dynamic behaviour of the measured electrical quantities during network disturbances is derived. A relay-model is implemented to study the behaviour...
This paper describes how an adjusted coaction of protection and distribution management systems in future distribution networks can help to improve security of supply. A high penetration with distributed energy resources is considered, challenges for network operation are discussed and protection concepts for both interconnected and islanded operation are developed.
Distributed generation (DG) is finding its way into the worldwide distribution networks very rapidly. As the existing networks were not created for this new structure of electricity production, the preservation of a reliable network operation and a high level of power quality is a big challenge for all network operators. In a study conducted by the University of Erlangen and the Erlanger Stadtwerke...
This paper is dealing with an urgent task of protection coordination in nationwide power systems. The coordination of overcurrent protection is strongly depending on the network configuration in contrast to distance or differential protection. Proposed concepts should be evaluated applied to the network. Nowadays numerical simulation tools like PSStradeSINCAL provide the possibility of a holistic...
This paper introduces a framework developed for image processing of synthetic aperture radar (SAR) images. It encapsulates features of modern hardware architectures, including symmetric and asymmetric multiprocessing, within an easy and intuitive to use application programming interface (API). The multiprocessing part is designed for unified usage of different architectures reaching from multicore...
