Test and Way to the Realization of Power System Voltage Stabilizer using LC
Resonance Circuit with Superconducting Coil and Capacitor
Shinobu KAWASHIMA㧖1㧘Akira NINOMIYA㧖2㧘Takeshi ISHIGOHKA㧖3ABSTRACT㧦These days, voltage stability of power system is very important for example insemiconductor industries. So, development of a device suppressing voltage sags in power system isexpected. In this article, the authors propose a new voltage stabilizing device using a LC resonancecircuit composed of superconducting coil and capacitor connected in parallel. This power system voltage
stabilizer acts automatically against a voltage sag or a steep voltage change, and it suppresses the voltage
drop for several cycles by releasing its stored energy. The authors have confirmed this principle
experimentally using a small model system using a LC resonance circuit with a superconducting coil anda capacitor. The experimental results and some theoretical analyses are presented.
