T. Ise et al., Compensation of harmonies and negative sequence components in line currentand voltage by a SuperSMES, IEEE APPL S, 9(2), 1999, pp. 334-337
A SuperSMES is composed of inverters connected in series to a power system
and another inverter in parallel, and a superconducting magnet for energy s
torage. It is a universal power quality controller because of its multi-pur
pose ability. The application presented here aims Pt a general filtering sy
stem in large industrial power consumers. The SuperSMES can provide sinusoi
dal and balanced voltage to loads which are sensitive for voltage distortio
n and unbalancing. It also eliminates current harmonics ana unbalance in th
ree phase lines of the distribution system, which now upstream of the conne
cting point. The ability was demonstrated by simulation results.
