Modelling of a three-phase concentric HTS-cable
چکیده انگلیسی
We have considered a three-phase concentric high-Tc superconducting (HTS)-cable with a copper shield neutral wire in a three-phase system. An equivalent circuit model describing the cable by the global quantities current and voltage has been developed, by which the effects of design parameters such as material, layer radii and pitch length can be investigated. The equivalent circuit consists of a nonlinear resistance, a hysteretic inductance (to model HTS), and an inductance (to model mutual inductances). The equivalent circuit is here extended with a by-pass resistance that models the silver matrix of the HTS tape. This enables to consider over-critical currents (i.e. beyond hysteresis saturation), whereby extra care must be taken for the numerical simulations. We have considered a design of fixed radii and have optimized the pitch length of each layer in order to have equal reactances for all phases.
