SCPT(Saturable Current Potential Transformer)여자시스템에 관한 연구

Many power plants m the thermal and hydraulic utilities, the pulp and the paper industry are faced with high maintenance and down time due to the aged excitation system For the life extension of the aged power plants, the static excitation system with SCPT type had been developed by KEPRI(Korea Electric Power Research Institute) This paper win discuss the design conception and the application results of system which includes the phase controlled rectifiers of the shunt type, SCPT and redundant analog controller
