Research On Preventing Electricity-stolen Technology Of Intelligent Watt-hour Meter

Watt-hour meter is a kind of cumulative or consume electric energy meters, it is mainly used for power supply enterprises with electricity customers, points of power grid and power plants and power substation settlement between active and reactive power of electric energy, and used in power supply enterprise line loss statistics, network loss. Watt-hour meter the emergence and development of more than one hundred years of history, with the rapid development of science and technology, watt-hour meter has expanded from induction watt-hour meter communication to communicate electronic watt-hour meter, then to electronic multi-function watt-hour meter, so far to the intelligent watt-hour meter, watt-hour meter in our country is moving in the direction of information interaction, intelligent electricity.Intelligent watt-hour meter has been vigorously promoting and application at home and abroad, at present about the intelligent watt-hour meter hasn’t been a unified definition, international rules on the intelligent watt-hour meter also have different technical standards or technical documents, that to a certain extent, limit the further promotion and development of intelligent watt-hour meter in the world.Intelligent watt-hour meter is a new type of all electronic watt-hour meter, by measuring unit, data processing unit, communication unit, etc, is an electric energy metering, information storage and processing, real-time monitoring, automatic control, information interaction, and other functions of watt-hour meter. Compared with the traditional ordinary watt-hour meter, intelligent watt-hour meter has the strong communication, data management and storage, key and new features such as security authentication. Intelligent watt-hour meter can provide more than the rate table, according to different season, time zone and holidays can set different electricity scheme respectively, and to record the user load curve, to help customers to optimize the power plan, develop a plan of power saving. The application of intelligent watt-hour meter, not only can realize the user information \"full coverage, full collection, complete the prepaid\", will also promote the electric energy measurement, metering and charging, the accuracy of inspection, standardization, automation, improve the power supply service level. The function of the intelligent watt-hour meter configuration, calibration, use and management ways are changing greatly, embodies the smart grid construction technical requirements of watt-hour meter. This paper analyzes the characteristics of intelligent watt-hour meter, advances some corresponding management measures, to enhance the level of standardization of intelligent watt-hour meter management.With the rapid development of electricity consumption, driven by economic interests, some power users at using illegal means to power, the administrative departments of electric power is put a lot of manpower and material resources to solve the problem of power theft, but to little effect. With the constant improvement of the power method, and the shortage of the existing measures of preventing electricity-stolen, mouth increasingly serious power phenomenon, power the country suffered huge economic losses and the administrative departments of electric power. Practical operation show that the single-phase electronic preventing electricity-stolen watt-hour meter can realize accurate measurement of electrical energy, and can accurately identify all kinds of power theft, real-time and low cost. Therefore, single-phase electronic preventing electricity-stolen watt-hour meter has wide market application prospect. With the development of power grid and the speeding up of electricity market operation, remote automatic meter reading has become an important subject of electricity management department. Electronic watt-hour meter instead of the induction watt-hour meter become an inevitable trend in the electric energy metering, remote automatic meter reading technology got rapid development, the research in view of the multi-function electronic watt-hour meter remote automatic meter reading technology also is very be necessary.In short, this paper starting from the reality needs of the national economy, in combination with the practical situation of electric power metering system, targeted for preventing electricity-stolen, got good practical results.
