Laboratory and Field Tests of Movable Conduction-Cooled High-Temperature SMES for Power System Stability Enhancement

Abstract

This paper introduces the first movable conductioncooled high temperature superconducting magnetic energy storage (SMES) system developed in China. The SMES is rated at 380 V / 35 kJ / 7 kW, consisting of the high temperature magnet confined in a dewar, the cryogenic unit, the converter, the monitoring and control unit, and the container, etc. The proposed SMES can be loaded onto a truck to move to a desired location and put into operation with easy connection. Laboratory and field tests have been carried out to investigate the operational characteristics and to demonstrate the SMES' effectiveness on improvements of system voltage stability and on the oscillation damping. Test results indicate that the SMES system has the features of fast response and four-quadrant power operation. The accessories for the movability of the SMES system are well designed. The system is feasible to be used in power systems.Index Terms--conduction cool, high temperature superconducting, moveable SMES, power system transient stability, superconducting magnetic energy storage Jiakun Fang received the Ph.D.

Multilevel Robust Design Optimization of a Superconducting Magnetic Energy Storage Based on a Benchmark Study

“…The second type is the high-temperature superconductor (HTS) SMES. Some SMESs made by different types of HTSs, such as BSCCO and YBCO, have been actively designed, fabricated and tested experimentally, for example, in-grid operations, around the world [6]- [9]. Recently, a promising movable HTS SMES system has been developed to maintain a long-term stable operation of the power system [10].…”

Performance Evaluation of SMES System for Initial and Steady Voltage Sag Compensations

“…Recently lots of SMES devices have been developed for voltage sag compensations and other power quality problems [2][3][4]. However, principal concerns in the applied superconductivity field mainly focus on the superconductivity-related techniques such as SMES coil design [5], superconducting switch preparation [6], current lead manufacture [7], refrigeration evaluation [8], system integration and test [9], etc..…”

Damping of Power System Oscillation using STATCOM Integrated with SMES

“…This has been expanded by A. R. Arsoy et al in [2]. Capability of SMES as an effective energy storage is described in [7], [8], [12]. Optimal location of SMES for improvement of voltage stability is described in [11].…”
