25KJ 초전도 에너지 저장장치의 전력제어와 발생고조파 분석

A Power Control of 25KJ Superconducting Magnetic Energy Storage and Analysis of AC Side Current Harmonics

This paper presents the experimental study to confirm the basic properties extract the operating problems of SMES. A new fast control system including u-computer and 12pulse power converter are designed and fabricated. The experiment of 25KJ SMES discharge and charge is carried out by I-C (Inductor-Converter) unit using a new proposed control system. The proposed control algorithm is proved by the simulations and control properties tests. It is also confirmed experimetally that SMES connected I-C unit controlled by this control scheme has an effects on compansating freguency fluctuation by independent active power control.
