This paper is a study on development of a new structured AMR/AMI(automatic meter reading/advance metering infrastructure) system. The developed system has a faster reading and is cheaper and easier to install compared to the existing AMR/AMI system. The system can be applied to AMR/AMI for five kinds of meters, electricity, gas, water, hot-water and calorie meter, which are used in most Korean households. Test results show that the developed system is both economical and reliable both in theoretical and practical applications. The resuts also show that the developed system is more suitable than existing system for AMR/AMI applications.

AMR(Automatic Meter Reading)/AMI(Advanced Metering Infrastructure) is actively deployed all over the world. efficient, economical, stable and reliable system need to push forward the AMR/AMI business, so various researchs are in progress. In electric power system of domestic, a transformer is connected average twenty to thirty households and PLC is possible to communication within household connected same transformer. So if server and data concentrator unit(DCU) share circuit line through communication between transformers, communication network is able to efficient. Therefore we design new communication method between DCUs and test it and demonstrate the performance.

Due to low cost, low-power, and scalability, ZigBee is considered an efficient wireless AMR infrastructure. However, these characteristics of ZigBee can make the devices more vulnerable to unexpected error environments. In this paper, a fault-tolerant wireless AMR network (FWAMR) is proposed, which is designed to improve the robustness of the conventional ZigBee-based AMR systems by coping well with dynamic error environments. The experimental results demonstrate that the FWAMR is considerably fault-tolerant compared with the conventional ZigBee-based AMR network.

In this paper, we present the AMI System mentioned as one of the main application areas in the M2M. To enable the AMI, it is essentially required to install, deploy and manage all the devices. Especially, Device Management technology is considered to be suitable for these AMI due to its advantages like, easy installation, remote FW/SW upgradeability. We investigate the fundamental operation of the DM and the design of the DM in the AMI is presented.

In the development of MDMS(Meter Data Management System) based on CIM(Common Information Model), which is international standard in information model and data exchange on power system, the two focused issues are the effective management of data collected in a shorter time period and the way to integrate services supporting legacy system to use the AMI(AMI, Advanced Metering Infrastructure) data. In this paper, we propose MDMS implementation methods and functions in AMI environment which are differ from existing AMR system environments in that the methods support bi-directional service infrastructure. The proposed MDMS in this paper has two unique features, one is the secure of interoperability by utilizing the CIM and ESB, the other is the improvement of field application by implementing system module based on components. On an implementation of smart grid, the result of proposed methods is expected to contribute to the efficient development and operation of CIM-based power system.

수용가 통합자원관리를 위해서는 수용가 측면에서 AMI(Adavanced Metering Infrastructure)기반의 부가서비스, 즉 전력정보관리, 전기품질관리, 수요응답 등 다양한 응용프로그램이 요구된다. 이러한 응용 기술은 이미 국내에서도 개발되어 사용되고 있다. 하지만 대부분의 응용프로그램들의 기능은 전력, 에너지, 전압, 전류 감시를 주요 기능으로 하고 있으며 모니터링 데이터를 활용하는 분석기능이 미흡한 상태이다. 따라서 우리는 우선 AMI/AMR에 대한 기술조사 및 관련 서비스 현황조사를 실시하였다. 다음으로는 AMI기반 서비스 사례를 분석하였다.

As an energy network infrastructure, which is capable of integrating energy related services such as AMR/AMI, Smart Grid, and Smart Water Grid, the Smart Utility Network (SUN) enables a paradigm shift from user-oriented networks to device-oriented networks. The SUN has some similarities to sensor networks in application and network requirements. Therefore it is required to investigate and analyze thoroughly existing related work in advance to design new network protocols for SUN. In this paper we analyze service requirements and design considerations for SUN and then present a design guideline of new network protocols for SUN by investigating existing low power protocols, data aggregation methods, and in-network storages.

Recently the existing one-way electricity system that combines information and communications technology to develop smart grid technology is made active. The core infrastructure of the smart grid, AMI smart meters to AMR system, the amount of power measured at the top to MDMS transmits data store. Smart meters utilizing information and communication technology to transfer data and power because of the existing security threats are expected, including the additional security threats. It exposes the privacy of consumers and industrial systems, such as paralysis is likely to result in the loss. In this paper to respond to these security threats in the environment smart grid. Also, We propose data transfer methods between smartmeter and MDMS and between home device and MDMS.

In this paper, a system that integrates a home concentrate unit(HCU) in a smart electricity meter to collects water, gas, hot water, and heating usage required for AMI has been proposed. The collected data could be transmitted to the in house display(IHD) and server to provide a more economical AMI system. The developed system is less expensive in the network configuration than the existing system, which could reduce the operating cost, and be easy to install. By applying the developed system, the usage of electricity, water, gas, hot water and heating could be measured and these make it easier to apply AMI system. The main contents of the development are the smart electricity meter and embedding of HCU into the smart electricity meter, and transferring these data to IHD and server to structure the AMI system. The each developed unit has been networked to structure the AMI system to perform the actual meter reading operation and show the result.
