Special Issue Information

Dear Colleagues,

Superconductors are known for their zero-resistance behaviour. Superconducting power applications can bring significant benefits across entire energy systems. For example, superconducting power transmission cables can deliver electrical energy over long distance without losses. Likewise, superconducting magnetic energy storage devices can promptly absorb and discharge energy to compensate energy systems well, and superconducting fault current limiters can immediately supress fault currents by using the intrinsic behaviour of superconductors. If superconductors are used in motors and generators (both rotating and liner), electrical machines can be designed with much smaller size and lower weight, but with much higher power density, which is the key to realizing high-efficiency zero-carbon power generation in future renewable energy systems and the full electrification of high-speed transportation networks, e.g., superconducting high-speed maglevs. This Special Issue welcomes contributions on a wide range of topics relating to superconducting applications for energy systems. 

We look forward to receiving your contributions.

The article presents a PSpice software-based numerical model of a superconducting transformer with HTS 2G SCS and SF windings for the analysis of electrical circuits, developed using PSpice version 24.1 (Cadence, 2024),which allows for the determination of equivalent parameters and properties of such a transformer in the steady state and in emergency states. The model has user-defined ABM (Analogue Behavioural Modelling) computational blocks and avails itself of the level 2 Jiles-Atherton magnetic hysteresis model and Rhyner’s power law describing the E-J relationship of the HTS superconducting tape. This model was experimentally verified by measurements of a real 10 kVA HTS transformer. On this basis, an extensive numerical model of a superconducting transformer with a more complicated winding structure and a higher power of 21 MVA was developed. For such a transformer, power losses were analysed and the time courses of resistance, current and temperature of superconducting windings made of HTS 2G tapes of the SCS type with a copper stabiliser and SF without a stabiliser were examined during emergency states, such as connecting the transformer to the network and operational short circuit. A discussion was carried out on the effectiveness of using both types of HTS tapes to limit the current in emergency situations posing a risk of loss of superconductivity and destruction of superconducting windings.

With accelerating urbanization, subway stations, as high-energy-consumption sectors, face significant challenges in maintaining power supply stability and ensuring power quality. This paper proposed a novel voltage compensation solution utilizing superconducting magnetic energy storage (SMES) to suppress voltage fluctuations in the traction system of a large subway station with multiple lines, which was caused by frequent acceleration and regenerative braking of multiple subway trains. Using the MATLAB/Simulink platform, a model of the traction power system with SMES for a large subway station with multiple lines was constructed. Appropriate control methods and hierarchical control strategies were used to suppress voltage fluctuations in both single-line and multi-line configurations at subway stations. The technical advantages of SMES in rapid response and efficient charging/discharging were explored. Overall, results show SMES with the novel control strategies can effectively suppress voltage fluctuations on both single- and triple-line configurations, validating the feasibility in mitigating voltage fluctuations and enhancing regenerative braking energy utilization.
