This paper presents a controlled discharge method and its characteristics of a liquid nitrogen cooled high temperature superconducting (HTS) coil in a small-scale superconducting magnetic energy storage (SMES) device. The maximum discharge time duration for the load and effective energy utilization factor of the SMES device itself are theoretically studied using an iterative calculation method. The...
A simplified DC superconducting magnetic energy storage (SMES) model is presented in this paper. The theoretical modeling and application topology are introduced with a new digital time-delay control method proposed to achieve required energy exchange. The theoretical analysis and simulation results of the steady and dynamic power and exchange processes verify its feasibility for the design, optimization...
Application development of high temperature superconductors (HTSs) has gone through from prospective enthusiasm to today's realistic realization since the HTS was discovered in 1986. Depending on the special characteristics of superconducting materials, with high power electronic devices, an experimental system for HTS coil has been developed. The experimental results obtained verify that the HTS...
