Research Of Comprehensive Energy Measurement And Management System

From the research of the development point of view, there are three main aspects in electric energy metering system: First, the acquisition of electric energy and computing technology, that is to meter and calculate current, voltage and other electrical parameters; Second,by what methods of data transmission, achieve reliable intelligent automatical meter-reading. The third is how to focus on the energy meter management and control. Being in accordance with the basic requirements of power station, automatically collect multi-function meter measurement values, and then record data, print the statements, and do some statistical analysis.Energy Measurement management systems are moving towards to intelligent, information-based, network-based direction. Energy metering system of electric energy to complete time-sharing site collection, storage, transmission. At the same time electricity meters to provide information to other applications, in order to complete the station's day-to-day power management, operation analysis, loss analysis. The system is power electricity production sector based on the management of the necessary measurement systems. Energy data may be EMS, transaction management systems, load forecasting, information systems be used. Therefore, the development of electric energy metering management system has an important practical significance.This paper analyzed the current status of power measurement and power production under the current regulatory requirements for the measurement of electricity a deeper transformation, which has designed a comprehensive management system for energy metering. The system is capable of accurate and efficient form of energy data collection and storage, with system parameters and management, statistical analysis of electricity, data view and print statements, as well as unusual circumstances, such as alarm function. power stations to meet the plant's day-to-day management needs of the measurement.Integrated management of energy metering system consists of data acquisition and management sub-system analysis subsystem is composed of three parts. Data acquisition subsystem is the basis of the system, management analysis subsystem is the core of the system. The former is mainly responsible for collecting a variety of meter data at the scene and dealt with accordingly, and finally saved to SQL Server 2000 server, users can also carry out management, data restoration, equipment management. Analysis of power management subsystem for the comprehensive analysis and management capabilities, to be completed by the power factor, voltage passing rate, load curve analysis and management, as well as the bus power balance analysis, the main variable, such as loss of function analysis, and lines and substations can be max-min statistical analysis of the load. The system stops the use of electricity for the plant management and the quantitative loss of main transformer quantitative analysis, substation reactive power optimization run provides an important basis for the data. It has been successfully applied in the actual number of company, and achieved good results.
