| dc.description.abstract | Distance protection systems are projected to have issues with the transition from centralizedgeneration with synchronous generators to Distributed generation when this is converterbased due to current limitations. In this thesis PSCAD was utilized to simulate differentscenarios where parameters are changed to observe protection system behaviour.This thesis is a continuation of a previous thesis where a switch based model was considered.In this thesis an averaged model was provided by SINTEF and the model was utilized on agrid model inspired by the Fosen wind power project.The parameters considered was fault resistance, fault location, fault type, and power plantrating. In most simulations performed in this thesis, the protection system was visiblyaffected. Increasing fault resistance lead to under-reaching. Fault located at increasingdistance from the relay increased the measured impedance. The LG fault type provedeasier to detect than LL and LLLG faults. Increasing power plant rating lead to moreaccurate measured impedance. | |
