Abstract

A superconducting magnetic energy storage system (SMES) was developed and has been tested in the field (at a large LCD TV plant in Japan) in order to confirm its performance at bridging instantaneous voltage dips, its long-term reliability and its standby loss. The developed SMES system can store up to 7.34 MJ of magnetic energy in superconducting coils using a NbTi Rutherford conductor with a maximum electric output of 5 MVA. The field tests began in July 2003. During operation, the performing compensatory action of the SMES system on instantaneous voltage dips within the actual system was confirmed. Through the field tests of the SMES system, technical proof of the specifications required to provide instant, effective compensation for instantaneous voltage dips was verified
