Abstract
The utility model relates to an intelligent bidirectional metering electric energy meter. The intelligent bidirectional metering electric energy meter comprises an electric energy metering module, a power measuring module, a display module and a power supply module. The power supply module is connected with the electric energy metering module, the power measuring module and the display module for supplying power to the modules. The power measuring module which is respectively connected with a public power grid and a distributed power supply network measures the power users deliver to the power grid and the power the power grid delivers to users in a real-time manner. The electric energy metering module receives data measured by the power measuring module in a real-time manner and achieves a bidirectional metering function characterized by on-grid energy metering and off-grid energy metering. The electric energy metering module is connected with the display module to achieve a metering result displaying function. The intelligent bidirectional metering electric energy meter with a reasonable design achieves a bidirectional metering function characterized by on-grid energy metering and off-grid energy metering and can remind users in a timely manner to consume and absorb distributed generated power.

Description
Technical field
The utility model belongs to electric energy meter technical field, especially a kind of intelligent bidirectional measuring electric energy meter.
Background technology
Along with the development of national economy, society increases rapidly the demand of electric power.For realizing the supply requirement of electric power, various countries concentrate substantial contribution to throw in the construction of the large-scale centralized power supplys such as thermoelectricity, water power and nuclear power and UHV (ultra-high voltage) remote conveying electrical network one after another.But large-scale electric system, when bringing huge interests to society and the people, has also brought potential great risk.Such as in September, 2011 U.S. China ink have a power failure on a large scale accident, in July, 2012 India to have a power failure on a large scale etc. be all due to local fault occurring in operation of power networks, brought out pernicious chain reaction, the scope and the degree that have expanded accident, finally lead to the great systematic failures such as electric network from collapsing and large-area power-cuts.Tremendous economic loss and social influence that these are had a power failure on a large scale and cause, caused the common concern of various countries, the whole world, these drawbacks that centralized large electrical network manifests, have caused our the deep thinking to power network development pattern, and people start the development model of electric system to look for another way.
Distributed power generation have pollution less, the advantage such as energy utilization rate is high, infield is flexible, it is compared with centralized generating, has saved power transmission and distribution resource and operating cost, has reduced the line loss of concentrated transmission of electricity; Distributed power generation can reduce electrical network total volume, improves electrical network peak valley performance, improves power supply reliability, is that the strong of large-scale power grid supplements and effectively support.Recent two decades comes, and most countries has been put on schedule distributed power generation, and people start the potential benefit of distributed generation system to launch conscientiously research.Along with the appearance of the grid-connected service suggestion of State Grid Corporation of China's distributed power generation and China governments at all levels are the day by day complete of main distributed power generation subsidy policy for take distributed photovoltaic, user's side distributed photovoltaic distributed power supply will increase year by year.
The grid-connected matter of utmost importance facing of user's side is exactly metering and billing how effectively, simultaneously for user provides useful generating and the aid decision making of electricity consumption aspect.Introducing due to power supply, exchange power between user and electrical network from unidirectional become two-way, on the one hand metering ability should adapt to this variation, and on the other hand, existing subsidy policy is higher to the generate power for their own use subsidy of part of user, bidirectional measuring ammeter is if Measurement accuracy bidirectional power, and show user in vivid mode, contribute to help user according to distributed power generation operating condition, and self workload demand, adjust in time electricity consumption strategy, maximize the on-site elimination of realizing distributed power generation.At present, there is no the electric energy meter that can simultaneously measure electricity volume and off line electric weight.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of intelligent bidirectional measuring electric energy meter is provided, and has solved distributed electrical source user and can not carry out the measurement problem of electricity volume and off line electric weight simultaneously.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of intelligent bidirectional measuring electric energy meter, comprise electric energy metering module, power measurement module, display module and power module, described power module and electric energy metering module, power measurement module and display module are connected for its power supply, power measurement is connected with public electric wire net and distributed power source net respectively, measure in real time the power of user to the power of grid transmission and electrical network to customer power supply, the measurement data of the real-time received power measurement module of described electric energy metering module and power measurement module also realizes electricity volume and the bidirectional measuring function of off line electric weight, electric energy metering module is connected with display module and realizes the Presentation Function of metering result.
And described electric energy metering module consists of single-chip microcomputer and peripheral circuit thereof.
Advantage of the present utility model and good effect are:
The utility model gathers the size of public electric wire net and distributed power source net exchange power by power measurement module, and by electric energy metering module, realize the bidirectional measuring function of electricity volume and off line electric weight, and show with arrow and digital mode that in real time trend flows to and size, the reminding user distributed power generation of dissolving in time, guiding user adjusts load configuration in time, improves user's side distributed power source rate of generating power for their own use.
