Analysis of Magnetic Field Application Effect on Fault Current Limiting Characteristics of a Flux-lock Type SFCL

임성훈 한국전기전자재료학회 2008 Transactions on Electrical and Electronic Material Vol.9 No.6

The magnetic field application effect on resistance of a high-TC superconducting (HTSC) element comprising a flux-lock type superconducting fault current limiter (SFCL) was investigated. The YBCO thin film, which was etched into a meander line using a lithography, was used as a current limiting element of the flux-lock type SFCL. To increase the magnetic field applied into HTSC element, the capacitor was connected in series with a solenoid-type magnetic field coil installed in the third winding of the flux-lock type SFCL. There was no magnetic field application effect on the resistance of HTSC element despite the application of larger magnetic field into the HTSC element when a fault happened. The resistance of HTSC element, on the contrary, started to decrease at the point of four periods from a fault instant although the amplitude of the applied magnetic field increased.

Operational Characteristics of Superconducting Amplifier using Vortex Flux Flow

임성훈 한국전기전자재료학회 2008 Transactions on Electrical and Electronic Material Vol.9 No.6

The operational characteristics of superconducting amplifier using vortex flux flow were analyzed from an equivalent circuit in which its current-voltage characteristics for the vortex motion in YBCO microbridge were reflected. For the analysis of operation as an amplifier, dc bias operational point for the superconducting amplifier is determined and then ac operational characteristics for the designed superconducting amplifier were investigated. The variation of transresistance, which describes the operational characteristics of superconducting amplifier, was estimated with respect to conditions of dc bias. The current and the voltage gains, which can be derived from the circuit for small signal analysis, were calculated at each operational point and compared with the results obtained from the numerical analysis for the small signal circuit. From our paper, the characteristics of amplification for superconducting flux flow transistor (SFFT) could be confirmed. The development of the superconducting amplifier applicable to various devices is expected.

위법한 가압류취소결정에 대한 국가배상에 있어 효력정지 미신청이 책임배제사유가 되는지 여부 - 대법원 2022. 3. 17. 선고 2019다226975 판결 -

임성훈 법조협회 2023 法曹 Vol.72 No.2

Regarding the state's compensation liability for illegal judicial decision, previous court precedents have shown that if the appeal process is not pursued, the state's compensation liability is limited. However, in the subject decision, it was determined that even if the appeal process was pursued by immediately filing an appeal, the state's compensation liability could be excluded if an application for suspension of execution was not made. In the field of international investment law, where the state's liability is actively contested in arbitral tribunal, the rule of finality applies. The rule of finality is about whether the responsibility of the state can be held in international investment arbitration only after going through all domestic appeal procedures. According to that rule, unless appeal procedures are exhausted, Even in the EU, where there has been active discussion on the violation of EU law by national supreme courts since the Köbler judgment, it is considered that the exhaustion of domestic remedies is necessary for the state's liability to arise. The basis for this is similar to the rule of finality in international investment arbitration, in that the state's liability in court arises when the judicial system as a whole fails to provide redress, and it is only through the parties' appeals that it can be determined whether or not there has been a failure of the overall judicial system. Under the court's hierarchical system, if a party does not appeal, the opportunity for such an appeal is eliminated as a result of the party's choice. Therefore, in cases where the appellant does not appeal, it is not confirmed that the "entire judiciary system" of the state did not provide an effective remedy, and the state compensation liability cannot be established. Therefore, failure to exhaust appeal procedure should be considered as not meeting the requirements for establishing the state's compensation liability, as it implies that there is no proof of the court's violation of obligation or illegality. However, the subject decision that there is no state compensation liability when ex officio examination is possible needs to be reconsidered. In cases where the court can conduct an ex officio review, even if the appellant does not appeal, the appellate court can review the trial. Rather, in the sense that the judicial system can be evaluated as imposing the duty to review ex officio, if an manifest breach is recognized, state compensation liability should be acknowledged more positively. 위법한 재판에 관한 국가배상책임에 대하여 판례는 재판에 대한 불복절차를 거치지 않으면 배상책임이 제한된다는 입장을 보여 왔는데, 대상판결에서는 그 범위를 확대하여 위법한 가압류취소결정에 즉시항고를 제기하여 불복절차를 거쳤다 하더라도 효력정지 신청을 하지 않은 경우 국가배상책임이 인정되지 않는다고 판단하였다. 국제투자법 분야에서는 국내의 불복절차를 모두 거쳐야 국가에 대한 책임을 물을 수 있는지에 관한 최종성 원칙과 관련하여, 불복절차를 밟지 않으면 국가가 적절한 사법시스템을 제공할 의무를 위반하였는지가 확정되지 않아 국가책임이 성립하지 않게 된다고 논의된다. EU에서도 국가책임 발생을 위해서는 불복절차 소진이 필요하다고 보는데, 그 근거로 국제투자법 분야에서의 최종성 원칙과 유사하게 법관의 재판에 대한 국가책임은 사법시스템이 전체적으로 권리구제에 실패한 경우에 발생하는 것이고, 당사자의 불복이 있어야 그러한 전체적인 사법시스템의 실패 여부가 확인될 수 있다는 점이 제시된다. 법원의 심급제 하에서 당사자가 불복하지 않은 경우에는 그 당사자는 상급심에서 구제받을 수 있음에도 불구하고 당사자가 불복하지 않아 그러한 기회가 상실된 것이다. 따라서 당사자가 불복을 하지 않은 경우에는 국가의 ‘사법시스템 전체’가 실효성있는 구제수단을 제공하지 못하였다는 점이 최종적으로 확정되지 않아 국가배상책임이 성립하지 않게 된다. 따라서 불복절차 미경유는 법원의 의무위반 또는 법원의 위법이 입증되지 못하여, 법관의 재판에 대한 국가배상책임 성립 요건 자체를 갖추지 못한 것에 해당하는 것으로 보아야 한다. 그렇지만, 직권에 의한 심사가 가능한 경우에도 국가배상책임이 성립하지 않는다는 대상판결은 재고(再考)를 요한다. 직권에 의한 심사가 가능한 경우라면 당사자가 불복하지 않더라도 상급심 법원은 하급심 재판에 대한 심사를 할 수 있다. 오히려 직권에 의한 심사를 하는 것이 사법시스템이 예정한 것으로 볼 수도 있다는 점에서, 그 사유만으로 불복절차 미경유로 국가배상책임이 전면적으로 배제된다고 보기는 어렵고, 명백한 오판이 인정되는 경우에는 보다 적극적으로 법관의 재판에 대한 국가배상책임 성립에 관하여 심사를 하여야 할 것이다.

히스테리시스 특성을 고려한 자속구속형 고온초전도 사고전류 제한기의 사고전류 제한특성 분석

임성훈,최명호,Lim, Sung-Hun,Choi, Myoung-Ho 한국조명전기설비학회 2007 조명·전기설비학회논문지 Vol.21 No.2

자속구속형 초전도 사고전류 제한기는 평상시 자기적인 결합에 의해 철심의 히스테리시스 손실이 발생하지 않는 특징이 있다. 그러나 사고시에는 사고전류증가로 인해 고온초전도 소자의 저항발생과 함께 철심의 포화가 발생할 경우 제한기의 사고전류제한 특성을 저하시키는 현상이 발생하게 된다. 따라서 본 논문에서는 이를 분석하고 억제하기 위한 설계방안을 도출하기 위해 자속구속형 고온초전도 사고전류 제한기의 구성요소인 자속구속 리액터의 히스테리시스 특성을 고려한 사고전류 제한특성을 분석하였다. 이를 위해 제한기의 등가회로와 사고전류 제한실험으로부터 히스테리시스 곡선을 도출하였다. 1, 2차권선의 인덕턴스 비에 따른 히스테리시스 곡선으로부터 인덕턴스비가 증가함에 따라 제한되는 사고전류크기는 증가한 반면 사고시 자속구속형 사고전류제한기의 구성요소인 철심의 포화가 억제됨을 확인할 수 있었다. The fault current limiting characteristics of a flux-lock type superconducting fault current limiter (SFCL) considering hysteresis characteristics of a flux-lock reactor, which is an essential component of the flux-lock type SFCL, were investigated. In the normal state, the hysteresis loss of iron core in the flux-lock type SFCL does not happen due to its winding's structure. From the equivalent circuit for the flux-lock type SFCL and the fault current limiting experiments, the hysteresis curves could be drawn. Through the hysteresis curves together with the fault current level due to the inductance ratio between the primary and the secondary windings, the increase of the number of turns in the secondary winding of the flux-lock type SFCL made the fault current level increase. On the other hand, the saturation of iron core was prevented.

Lipid Oxidation of Sodium Caseinate-stabilized Emulsion-gels Prepared Using Microbial Transglutaminase

임성훈,김하람,최승준,문태화 한국식품과학회 2015 Food Science and Biotechnology Vol.24 No.6

Development of lipid oxidation in casein-stabilized emulsion-gels prepared using microbial transglutaminase was investigated. The oxidative stability of emulsion-gels was assessed based on measurement of the amount of lipid hydroperoxide, hexanal, and 1-octen-3-ol. Profiles of lipid hydroperoxide showed that formation of lipid hydroperoxide was reduced in emulsion-gels, compared with emulsions, regardless of the storage temperature. Quantitative analysis of hexanal and 1-octen-3- ol showed no significant (p>0.05) difference between oxidative stabilities of emulsion-gels and emulsions. The storage temperature did not affect formation patterns of hydroperoxide, hexanal, and 1-octen-3-ol. Transglutaminase can be a useful tool for retardation of lipid oxidation based on formation of emulsion-gels.

Study on Protective Relay Operation in a Power Distribution System with a Trigger-Type SFCL Using Twice Triggering Operations

임성훈,김진석 한국전기전자재료학회 2018 Transactions on Electrical and Electronic Material Vol.19 No.2

This paper proposes a trigger type superconducting fault current limiter (SFCL), which consists of a switch, two superconductingmodules, and two series connected current limiting resistances (CLRs), using twice triggering operations. Thesuggested trigger type SFCL has twice the triggering operations according to the amplitude of the fault current. However,these operations are thought to aff ect the operation of the protective relay in a power distribution system. According to thefault conditions that aff ect the operation of the protective relay in a power distribution system, the fault location was selected. With two representative fault locations, the fault current limiting and the bus-voltage sag suppressing characteristics in apower distribution system with the suggested SFCL were analyzed. For comparative studies, the operation of the protectiverelay due to the conventional trigger type SFCL using one CLR was additionally described.

션트리액터의 자기결합을 이용한 초전도전류제한기를 구성하는 초전도소자들의 전력부담 분석

임성훈,Lim, Sung-Hun 한국전기전자재료학회 2010 전기전자재료학회논문지 Vol.23 No.1

The power burden of high-$T_c$ superconducting (HTSC) elements comprising superconducting fault current limiter (SFCL) using magnetic coupling of shunt reactors was analyzed. The magnetically coupled shunt reactors play a role in distributing the even power burden between HTSC elements comprising the SFCL, which contributes to the effective current limiting and recovery characteristics of the SFCL. It was confirmed through the comparative analysis on the SFCLs with both the magnetically coupled and the magnetically uncoupled shunt reactors that the magnetically coupled shunt reactors could improve the SFCL's performance by equalizing the power burden of HTSC elements.

1-Bit 합성곱 신경망을 위한 정확도 향상 기법

임성훈,이재흥 한국전기전자학회 2018 전기전자학회논문지 Vol.22 No.4

In this paper, we analyze the performance degradation of previous 1-Bit convolutional neural network method andintroduce ways to mitigate it. Previous work applies 32-Bit operation to first and last layers. But our method applies32-Bit operation to second layer too. We also show that nonlinear activation function can be removed after binarizinginputs and weights. In order to verify the method proposed in this paper, we experiment the object detection neuralnetwork for korean license plate detection. Our method results in 96.1% accuracy, but the existing method results in 74%accuracy. 본 논문에서는 기존 1-Bit 합성곱 신경망의 성능 하락에 대한 분석과 이를 완화하기 위한 방안을 제시한다. 기존의 연구는첫 번째 층과 마지막 층만 32-Bit 연산을 적용하고 나머지 연산은 1-Bit 연산을 적용한 것과 달리 본 논문에서는 두 번째 층도 32-Bit로 연산한다. 또한 입력과 가중치를 이진화하고 1-Bit 연산을 적용한 후에는 비선형 활성화 함수를 제거할 수 있음을 제시한다. 본 논문에서 제시한 방법을 검증하기 위해 차량 번호판 검출을 위한 객체 검출 신경망을 실험하였다. 기존의방법으로 학습한 결과보다 정확도가 74%에서 96.1%로 상승하였다.
