Field Test Result of 10MVA/20MJ SMES for Load Fluctuation Compensation

SMES of the 10 MVA for the power control in power system has been manufactured, and connected to a real power grid. In addition, innovative basic researches, for example, low cost converter, maintenance-free cryo-coolers, inter-locks system and so on, have also been developed. The SMES was installed in the metal rolling factory with hydro power plant. Field test has been carried out for load fluctuation compensation. SMES was able to compensate for the active power according to the fluctuating load, and confirm the situation with a smooth load change of 11 kV bus of hydro power stations. In this paper, field test results will be presented.
