This paper is about the economic analysis of the replacement of electric facilities in the production facilities. As the interest of energy is increasing, the efficiency of facilities become more important. So, in this paper, we diagnosed facilities, especially electric motors, in the plant and calculated the operating efficiency, power loss with the load factor. And when we replace these facilities into high-efficiency motors, we also calculated new energy efficiency, energy loss and economic analysis through capital recovery factor. As a result, we economically proved that using high-efficiency motor is more beneficial than using non-high-efficiency motors in the model process.

Recently, more electric power facilities have been miniaturized and it is noted that the facilities maintenance will be essential through operation optimization. In this paper we applied and examined the operation optimization of electric power facilities by applying Matrix system which can improve reliability to minimize outage and recover failure rapidly when blackouts happen at 25.8kV Gas Insulated Switchgear(GIS). The fundamental problem for facilities maintenance of GIS can happen due to indeterminable internal state in real time. Matrix optimization organizes action states in all containers which contain pressurized $SF_6$ Gas such as circuit breaker, disconnector switch, bus for utilizing them each area. Then, we connect it with power system to monitor and control internal state remotely in real time, and we can minimize blackout zone or outage. Considering above process, we improved stability of overall facilities.

This paper presents a modeling of railway facilities based on object-oriented software development technique for train operation simulation program. Railway network is decomposed by Line Structure Model and Signal System Model which can be composed to make the train routes and train performance calculation. A brief explanation of class design about these model is provided.

It's a general tendency that electrical facilities of power station become a large size and increase in number because electrical facilities become big and complicated with internal industrial development and economic growth. So, electrical accidents were increased in this electrical facilities of power station. Therefore, in this paper we compared domestic and foreign standard on safety environment of power station. From this, we draw several questions in case of installation on power station and we proposed a draft of relative standard to apply in power station.
