Superconducting magnetic energy storage (SMES) devices offer attractive and unique features including no theoretical limit to specific power, high cycling efficiencies and charge/discharge rates, and virtually no degradation with cycling. The mass-specific energy density (MSED) of SMES systems; however, falls short of many needs. This paper examines SMES energy densities of solenoid-type...
It is envisioned that High Temperature Superconducting (HTS) power cables could replace conventional cables in applications where space and weight are the limiting design factors. In situations where significantly higher power densities (both volumetric and gravimetric) are required and variable power ratings are preferred, it is necessary to operate HTS cables at temperatures lower than the...
Since energy deficiency and global warming become most serious, it is anticipated global PV installment will reach 230 GW. China has urgent need to use PV to replace its coal-based (over 70%) energy structure. In last 4-5 years China becomes the world largest PV produce and user. Moreover, in China’s plan, about half of the PV electricity are generated from distributed systems, the other half...
Superconducting and cryogenic power system components are understood to have strong advantages for MW-class power systems, such as greatly reduced weight, size and heat loss and increased energy efficiency. In this work, the unique properties and technical readiness assessment of cryogenic and superconducting components will be reviewed, and compared to alternate traditional technologies...
The quick adjustment capability of the excitation system plays a very important role in maintaining the normal operation of superconducting machines and power systems, but the eddy currents in the electromagnetic shield of superconducting machines will hinder the exciting magnetic field change and weaken the adjustment capability of the excitation system. To analyze this problem, a finite...
