The cables installed to deliver high electric power from a generator at a thermoelectric power station are XLPE (or CV) cables. Depending on the installation and usage conditions, the cables in operation start deteriorating from the time of initial operation. Some cables can cause accidents due to faulty construction or other environmental factors. In order to prevent cable accidents, regular auditing of power cables is required. We have invented a measuring device for systematic surveillance and prevention of accidents, and installed the device at Korean Western Power Co. Ltd. which measures load currents through the cables. In this paper, we present the load current measured using our device, analyze the load characteristics by measures current, compare the ampacity defined by IEC standard, and present a basic data to obtain the temperature of cable conductors.

The Study is for improvement of power plant equipment environment. Emergency lamp already installed In transformer substations has weak Illuminance. Because emergency battery is limited and incandescent electric lamps installed has low intensity of illumination and bad efficiency. It is too dark to operate many types of equipment in work Therefore this paper proposes that we use fluorescent lamp instead of incandescent electric lamp and change the old illumination standard for evident standard from the can coup with accident rapidly.

최근 주요정보통신기반시설 대상의 사이버 공격이 급격하게 증가하고 있다. 특히, 발전시설 주요정보통신기반시설에 사이버 공격 발생 시 전력 공급 중단으로 인하여 대규모 정전사고가 발생할 수 있다. 따라서, 발전시설 대상의 사이버보안 관리가 중요하며, 주기적인 사이버보안 평가가 필요하다. 미국 EPRI(Electric Power Research Institute)에서 발전시설 대상 사이버 보안조치 평가 방법론인 TAM(Technical Assessment Methodology)을 개발하였고, 최근 아랍에미리트(UAE, United Arab Emirates) 바라카(Barakah) 원자력발전소에서 사이버보안 평가를 위해 TAM을 활용하였다. 본 논문에서는 발전시설 사이버보안 평가 방법론인 TAM을 분석하고, 국내 발전시설 사이버보안 평가에 활용 방안을 제시하고자 한다.

1882년 최초의 발전소가 생긴 이래로 전기는 경제성장의 필수적 요소가 되었다. 전기는 빛의 속도로 움직이는 특성으로 인해 정전과 같은 사고에 대처하기 위해 중앙 집중적이며 폐쇄적인 체계를 가졌으나 온실가스 감축 협약, 신재생에너지의 확산 등으로 근본적인 변화를 맞이하고 있으며 최근 인공지능의 급격한 발전으로 전력망 관리에도 인공지능을 도입하는 것에 대한 논의가 필요한 시점이다. 본 논문은 전력망에 인공지능이 결합된 에너지 로봇이라는 개념을 제안하여 점차 가속화 되고 있는 지능화의 흐름 속에서 전력 시스템이 나아가야 할 방향에 대해 고찰하고자 한다.

송전선, 변전소, 발전소 등의 전력설비에 있어서 애자장치의 오손은 지락사고나 코로나 유발에 의한 환경장애 등의 원인이 되고 있어 염분에 의한 애자장치의 오손 대책이 설비 관리에 있어서 중요한 부분을 차지하고 있으며, 이를 위해서는 염분 오손도의 측정이 선행되어야 한다. 본 논문에서는 염분 오손도를 상시 자동으로 측정할 수 있는 방법으로서 제안되고 있는 전자식 애자 이용법, 열전 반도체를 이용한 전도도 측정법, Nd:YAG 레이저법, 레이저 광센서와 프리즘을 이용한 염분 오손도 측정법, 정전용량 검출센서를 이용한 염분 오손도 측정법, 백금 전극을 이용한 누설전류 측정법과 같은 염분 오손도 측정법을 소개하고자 한다.

The Fukushima Nuclear Disaster in 2011 and California Power Failure in 2001 are examples of the importance of the power plant safety management that caused huge national loss with a power-related mass casualty incident. In a situation where humans cannot live without electricity, efforts to strengthen the systematic firefighting safety management in power plants that produce electricity with large amounts of hazardous materials as fuel, such as nuclear energy, coal and gas, are essential to protect life and prevent property loss and stable economic growth from fire explosion accident or radiation leak due to the negligence of safety management and natural disasters such as earthquakes, which has recently become an issue. This study examined the operating situation of firefighting safety management in power plants with firefighting officials employed by five power generation companies including Korea Southern Power Co., Ltd. and Korea Hydro & Nuclear Power Co. Ltd., which are in charge of the domestic power supply. As a result, for the systematic firefighting safety management of power plants, improvement plans were drawn, including the development of an effective business manual and a comprehensive management system, the substantiality of firefighting safety education, and the strengthening of seismic designs to prepare for earthquakes.

With the development of industry these days, the demand for electric power increases and the larger capacity for power transfer is required. The scales of facilities should become larger; and the relative systems are required to operate with a higher degree of reliability. Therefore, stabilization of electric power systems is an important issue. The high degree of reliability required in the process of production and supply of electric power is an essential part of industrial society. Accident such as blackouts causes a hugh amount of economic losses to the high-tech industrial society dependent upon electric power. In this paper, in order to determine a stable operation of high-voltage power cable, used as a unique means of delivering electric power generated at a power station, we figure out the time rate of change of insulation resistance following a decay accelerating factor Arrhenius equation. With the data from the insulation resistance, we can determine the lifetime of power cable in operation.

The recent incidents of Nuclear Power Plant(NPP) gave rise to a total power outage caused by the loss of the functions of the off-site and the emergency power supply. Currently, emergency power supply of NPP have been taken into account by Li-ion batteries instead of existing lead-acid batteries. In order to judge the applicability of the cylindrical Li-ion battery, it is necessary to analysis the results of various electrical tests. This paper investigates the basic electrical characteristics test of three types of cylindrical batteries in order to select the most suitable battery and estimate state of battery through equivalent circuit model and propose method to solve the problem.
