OPNW, which takes charge of the outer neutral wire role and the inner optical network role, was developed at the first time among nation and substituted the neutral wire of distribution line between electric power substation and neighboring station. This paper refers to results about its optical character measured periodically, and examines closely whether the unique matter will be occurred or not about the role of neutral wire during more than one year. Also, established OPNW became a new chance to distribution facility's working by establishing remote portrait supervisory system and doing remote supervisory about essential equipment of distribution line.

Recently, it is focused on a methodology to estimate a order of precedence investment in distribution power system under competitive electricity market. This paper suggests methodology to evaluate the order as using a sensitivity of system interruption cost in distribution system regarding a failure rate of distribution components. In this paper, by using one of feeder in RBTS model, the order is assessed to compare valuation about sensitivity of interruption cost with valuation about sensitivity of estimated reliability indices. In conclusion, it is shown that results of precedence investment based on each methods are difference.

The high quality power is consisted with uniform frequence, no interruption and uniform voltage. In these components, the voltage of the distribution systems affects making economic distribution facility and improving power quality. This paper describes on the voltage apportion rates of the distribution systems in KEPCO.

Pattern matching is increasingly being employed in various researches as health care service, RFID-based system, facility management, and surveillance. Geosensor filter correlates a data stream to match specific patterns in distribution environments. In this paper, we present a geosensor query language to represent efficiently declarative geosensor query. Geosensor operators are proposed to use for fast query processing in terms of spatial and temporal area in distribution environments. We also propose a geosensor filter to match new query predicates into incoming stream predicates. Our filter can reduce the volume of transmission data and save power consumption of sensors. It can be utilized the stream data mining system to process in real-time various data as location, time, and geosensor information in distribution environments.

This study aims to discuss the location characteristics and present distribution of facilities in the rural community. The purpose of this study is to suggest the basic data of the planning of facilities corresponding to the living sphere in community. The circumstances, location and distribution of the rural area facilities was analyzed through field investigation and interview. lt is necessary for ameliorating the income of inhabitants and the status of living environment to make a general local plan in developing rural area. That will be a solution to tackle the decreasement of population in the rural area. The survey's result is observed different by the feature of rural area, adjacence with near rural center, scale of rural center. So a standard of the various facility's arrangement plan must be established, and it must be enlarged in rural area.

The dry and wet flashover characteristics on the contaminated distribution facilities was investigated. The test were carried out on the suspension insulator, line post insulator, lightning arrester, cut off switch, etc. In the dry state, the flashover voltages of facilities contaminated with B, C, D classes are similar to the non-contaminated ones. However, in the wet state, the flashover voltages of facilities contaminated with B, C, D classes are decreased. The flashover voltages of some few facilities show under the standard value. This results indicate that the high humidity may cause the flashover on distribution facilities.

The overvoltage generated by the lightning strokes has been doing considerable damage to the distribution network as well as the consumer facility until now. Because most of the lightning strokes are accompanied by a storm, the aftermath of damage to the consumer is so serious. Therefore it is very important to survey the optimal operation plan by the field test of distribution lightning facilities. In this paper we have accomplished the field test to verify the impulse characteristic of Secondary Arrester(SA), and analyzed the effect of the SA in power distribution system.

The nuclear power Plant onsite AC electrical power sources are required to supply power to the engineering safety facility buses if the offsite power source is lost. Typically, Diesel Generators are used as the onsite power source. The 125 VAC buses are part of the onsite Class 1E AC and DC electrical power distribution system. The DC power distribution system ensure the availability of DC electrical power for system required to shutdown the reactor and maintain it in a safety condition after an anticipated operational occurrence or a postulated Design Base Accident. Recently, onsite DC power supply system trip occurs the loss of system function. To obtain the performance such as reliability and availability, we analyzed the cause of battery charger trip and described the improvement of DC power supply system reliability. Finally, we provide reliability performance criteria of charger in order to ensure the probabilistic goals for the safety of the nuclear power plants.

This paper proposes an advanced reclosing scheme to improve power quality in power distribution systems. When a fault occurs in distribution system, the proposed schema determines the number of reclosing shots and its intervals according to the magnitude of fault current. Thus, an advanced reclosing scheme takes account of the power quality problem in customer\`s and the damage in electric facilities. To verify the effectiveness of the proposed scheme, a numerical simulation that calculates various indices to consider the reliability and the other effects on electric facility, in carried out with actual field data.
