AbstractA very common kind of fault that appear in an electrical power system is the short-circuit fault, which were traditionally handled by the use of protective devices like fuses or circuit breakers which would disconnect the power supply to protect the components of the network. An alternative to these are fault current limiters (FCL), which are protective devices that limit or suppress the high-magnitude currents created during a short-circuit fault, thereby preventing damage to sensitive equipment and also aid in providing uninterrupted power supply to the consumers. A saturated iron-core superconducting fault current limiter (SISFCL) employs the ferromagnetic property of its core material to automatically suppress high-magnitude currents. In this paper, the performance of an open-core type three-phase SISFCL design is evaluated against three different kinds of short-circuit faults. The analysis is performed using finite element modelling (FEM) in the ANSYS Maxwell software environment.

Park Transformation

Abstract Long transmission lines have to be compensated to enhance the transport of active power. But a wrong design of the compensation may lead to subsynchronous resonances (SSR). For studies often park equivalent circuits are used. The parameters of the models are often determined analytically or by a three-phase short-circuit test. Models with this parameters give good results for frequencies of 50 Hz and 100 Hz resp. 60 Hz and 120 Hz. But SSR occurs at lower frequencies what arises the question of the reliability of the used models. Therefore in this publication a novel method for the determination of Park equivalent circuit parameters is presented. Herein the parameters are determined form time functions of the currents and the electromagnetic moment of the machine calculated by transient finite-element simulations. This parameters are used for network simulations and compared with the finite-element calculations. Compared to the parameters derived by a three-phase short-circuit a significant better accuracy of simulation results can be achieved by the presented method.
