Using much electric resistivity survey to design or preservation administration of facilities. However, By survey method that electric resistivity survey grasps special quality in base by potential difference creating artificial current in underground, Is influenced in electric resistance propensitys of various underground utilities in base. This Study selects dam 1 place that could grasp well underground situation and studied electricity interference effect by effect of underground utilities. Grasp underground utilities of dam interior, and control and observed accuracy with survey wave because various pole space. Through this Study, wish to present survey method of electric resistivity survey at design or survey of preservation administration dimension after with drawn result.

Recently, foreign utilities emphasize the importance of the value-added services based on Information Technology(IT) as one of the strategic technologies for establishing a new power system in the future digital society. They develop many different types of the value-added services and apply the systems for customer. In domestic case, the data from the Automatic Meter Reading (AMR) System is used only for calculating the tariffs. Data from the AMR system can be strategic assets for utilities to provide the value-added services for customer. Development of the value-added services for utilities and customer needs processing and managing the AMR data. In this paper, the energy consulting service, which is adequate to new power system environment, is suggested for development of the value-added services. The application of the suggested service will bring the effect of reducing the monthly bill for customer. Also the service will give not only the effective demand side management(DSM) and load control, but also reduction of the investment for utilities.

Recently, there are two big paradigm shifts in the global electric power industry. First, the maintenance practice is gradually moved from time-based activities to reliability-centered activities. On the other hand, asset management is emerging as a new framework to maximize the efficiency of investments. The two paradigms are mutually exclusive in natural. Thus the power utilities usually chose the investment alternative on the basis of reliability in the past. But today's changed business environment - competition -requires the power utilities to compromise the trade-off of reliability effects and economics of investments. This paper shows what and how to interpret the reliability effects of distribution system investments into financial indicators beneficial for power utilities's managers to make decision on the perspective of corporate value.

Using much most electricity electric resistivity survey by nondestructiveness inquiry enforcement design of country base equipment business and facilities preservation administration dimension electric resistivity survey sends and cause much effects in survey believability by electricity medium of survey personality survey contiguity that grasp base special quality by potential difference flowing current artificially in base. Is item that enforce in most in-suite although when make electric resistivity survey until present, electricity medium or effect research by electricity origination was gone much. There is shortcoming that must be difficult to know correct underground utilities establishment state in-suite in this research and do comparison examination running parallel drilling investigation to heighten believability of electric resistivity survey. Did to dam that censure data that regulate grading from construction and is censure construction which can know correctly interior base situation comparatively to electricity medium of interior and electricity eruption won of contiguity and base condition (base rock).

Objective signs are everywhere that the stationary energy storage market is growing up quickly. The use of distributed resources such as solar photovoltaics and electric vehicles are expanding at a rapid pace, creating technical challenges for the distribution system that will require energy storage and a new generation of software to address. This paper is intended for distribution utility managers and executives and makes the following points: ${\bullet}$ Utility-integrated (as opposed to merely grid-connected) energy storage projects represent a distinct, new wave of industry growth that is just getting underway and is required to manage distributed energy resources moving forward. ${\bullet}$ Utilities and the energy storage industry have important roles to lower risk in adopting this technology - thereby enabling this wave of growth. ${\circ}$ The industry must focus on engineering energy storage for adoption at scale - including the creation and support of software open standards -both to drive down costs and to limit technology and supplier risk for utilities. ${\circ}$ Utilities need to take a program-based, rather than a project- based, approach to this resource to best balance cost and risk as they procure and implement energy storage. By working together to drive down costs and manage risk, utilities and their suppliers can lay the energy storage foundation for a new, more digital distributed electricity system.

This paper describes the safety condition of power utilities installed on underground premises when flooding occurs. As advance preparations, the statistical data were investigated based on the rainfall trend; the flooding damage; the power utilities installation; the electric shock accidents, and domestic md foreign regulations pertaining to the power utilities installation on underground premises were also compared and analyzed. After the preliminaries, the safety condition of underground power utilities was inspected at site and the results were reflected on considering countermeasures. Based on the further studies, the regulations closely related to the underground power utilities installation can be modified.

Load Management, is originated from efficiency improvement of energy use, or energy conservaion. Traditionally, electric utilities have constructed new power plants to meet the steadily increasing electricity demand. Power development planning, however, is becoming more difficult in the countries like Korea, Japan, and the United States, and increasing concerns about global environmental problems necessitate changes from existing supply-side options based on fossil-fuel to environmentally agreeable supply strategies. This paper discusses the demand side management strategy with emphasis on the concept, implementation scheme, and current practices employed in utilities.

Power Companies worldwide are undergoing tremendous change in the Automation issues. It becomes a worldwide trend that the power utilities focus their attention to the automation of their power plants and substation systems, employing recent advanced communication protocols. In this paper, we discuss the standard communication protocols which can be applied in the automation systems to help utilities reduce their operation and maintenance costs while at the same time meeting new requirements for communications to RTUs and intelligent electronic devices(IEDs). Especially, we introduce EC 61850 protocol which is developing for international standard by IEC.
