“…But, it offers maximum resistance during fault condition and this depends upon the current density & electric field intensity around the SCFCL and its temperature. SCFCL transits super conducting state to a normal state within 1ms and return to the low resistance state quickly after the limitation of fault currents [15].…”

Nowadays multi-terminal voltage source converter based high voltage direct current (VSC-HVDC) system stands as an interesting solution to efficiently connect a number of offshore wind farms. But the VSC based HVDC system is more vulnerable to DC line faults due to the high discharge current from the DC link capacitance. In view of this, a superconducting fault current limiter (SCFCL) is a possible device which can mitigate the consequences of DC line faults effectively. The main objective of this paper is to improve the dynamic performance of an offshore wind farm connected multi-terminal VSC-HVDC transmission system by incorporating SCFCL under various perturbations. Here, the MTDC system along with the SCFCL is modelled in MATLAB/Simulink and the results are presented for various AC/DC fault conditions.

In this paper, different methods to limit short circuit currents in DC traction networks are compared. Typically, DC traction networks are supplied by the AC grid by means of an uncontrolled diode bridge rectifier. In case of a low-impedance short circuit fault between catenary and rail, the fault current reaches a large value. For densely meshed networks the mechanical circuit breakers can become too slow. The methods studied are applying fault current limiters, faster interruption of fault currents and adding controlled rectifiers. The fault current limiters considered are a reactor and a superconducting fault current limiter (SFCL). For faster interruption of fault currents, a hybrid circuit breaker is investigated. Simulations show that the short circuit current can be limited considerably by installing limitation devices after the rectifiers, when the short circuit occurs close to a substation. Fast interruption of the fault or application of the SFCL results in the strongest reduction of the short circuit current.

“…2005). Series reactors and solid state fault current limiters are also widely used, although these insert a high impedance causing a continuous voltage drop and power losses during normal operation (Ye and Juengst 2004). However, superconducting fault current limiting technology can stand up to all these difficulties, preserving the stability and reliability of the power system with minimum losses under normal conditions (Angeli et al.…”

Power flow analysis and optimal locations of resistive type superconducting fault current limiters

Based on conventional approaches for the integration of resistive-type superconducting fault current limiters (SFCLs) on electric distribution networks, SFCL models largely rely on the insertion of a step or exponential resistance that is determined by a predefined quenching time. In this paper, we expand the scope of the aforementioned models by considering the actual behaviour of an SFCL in terms of the temperature dynamic power-law dependence between the electrical field and the current density, characteristic of high temperature superconductors. Our results are compared to the step-resistance models for the sake of discussion and clarity of the conclusions. Both SFCL models were integrated into a power system model built based on the UK power standard, to study the impact of these protection strategies on the performance of the overall electricity network. As a representative renewable energy source, a 90 MVA wind farm was considered for the simulations. Three fault conditions were simulated, and the figures for the fault current reduction predicted by both fault current limiting models have been compared in terms of multiple current measuring points and allocation strategies. Consequently, we have shown that the incorporation of the E–J characteristics and thermal properties of the superconductor at the simulation level of electric power systems, is crucial for estimations of reliability and determining the optimal locations of resistive type SFCLs in distributed power networks. Our results may help decision making by distribution network operators regarding investment and promotion of SFCL technologies, as it is possible to determine the maximum number of SFCLs necessary to protect against different fault conditions at multiple locations.
