Abstract: 본 발명은 제어봉 구동장치 제어기기용 전력변환장치에서의 사이리스터 (thyristor) 고장검출방법에 관한 것으로, 특히 사이리스터의 고장 유무를 감시하여 고장을 검출함으로써 원전 가동율 향상에 기여하고자 함에 관한 것이다.
본 발명의 제어봉 구동장치 제어기기용 전력변환장치에서의 사이리스터 고장검출방법은 정류된 코일의 전압을 읽는 제1단계; 상기 코일에 흐르는 전류의 명령을 읽는 제2단계; 상기 전류 명령의 변경 여부를 검사하여 사이리스터의 고장 발생 여부를 검사하는 제3단계; 및 상기 고장이 발생하면 긴급경보를 하고, 고장이 발생하지 않으면 제1단계로 피드백하는 제4단계를 수행하는 방법에 기술적 특징이 있다.
따라서, 본 발명의 제어봉 구동장치 제어기기용 전력변환장치에서의 사이리스터 고장검출방법은 종래의 고장검출방법보다 더 안정적이고, 정지모드시에서도 사이리스터의 고장 유무를 상시 감시하여 고장을 검출함으로써 사이리스터의 고장에 의한 발전소의 불시 정지를 예방할 수 있기 때문에 원전 가동율 향상에 기여하는 효과가 있다.-

Abstract: The present invention controls organic reactive power of a power generation system and controls a DC stage voltage of a power converter by classifying voltage and current of an induction generator stator and an induction generator rotor having nonlinear characteristics respectively. The present invention can be stably mounted by designing a controller by integrating a stator and rotor side converter, and can be included in a nonlinear control input to remove all of differential terms which can cause instability of the system. Even if a time-variable disturbance factor occurs by uncertainties of a wound-rotor induction generator model or external noise or the model has unknown parameters, an apparatus for controlling the wound-rotor type induction generator using a backstepping robust adaptive control scheme can maintain a stable control operation.
