Description
Technical field
The present invention relates to a kind of urban distribution network electricity distributing and metering system, belong to electric quantity metering technical field.
Background technology
At present, domestic consumer's Electro-metering is generally by table look-at or adopts digit chip plug-in card to measure, scene labor intensity of checking meter is large, and adopt the metering of digit chip plug-in card also to come with some shortcomings, higher to cards ask, and there is certain fabrication cost, therefore, be not adapt to very much in some places.And at present along with the development of communication network, more and more intelligent network and metering outfit have occurred, also provide some quick and convenience to Intellectualized metering, therefore, can utilize intelligent mode carry out control metering, improve metering efficiency and security, correctness.
Summary of the invention
The object of the present invention is to provide a kind of urban distribution network electricity distributing and metering system, so that can be more accurate, safely, realize measuring for electrical network distribution quickly, improve the efficiency that metering effect improves metering.
To achieve these goals, technical scheme of the present invention is as follows.
A kind of urban distribution network electricity distributing and metering system, comprise master data processor, wherein, master data processor is connected with communication interface, storer, communication module, button, GPRS module, light-emitting diode display, clock circuit, pulse output and integrating metrology chip, integrating metrology chip is connected with voltage branch circuit and instrument current transformer, voltage branch circuit is connected with consumer networks respectively with instrument current transformer.
Further, communication interface is provided with communication network to be connected with Information Analysis Center.
Further, voltage branch circuit is arranged in intelligent electric meter, in order to measure applied voltage situation.
Further, consumer networks access is in intelligent electric meter, and instrument current transformer is connected in consumer networks.
This contrive equipment forms primarily of intelligent electric energy meter, mutual inductor, high-speed communicating network, information analysis processing enter and management system supporting with it, use the new technologies such as modern digital communication, computer hardware technique, electric energy metrical, form one with digital data transmission, advanced IT application, the intelligentized opening type metering system of manipulation, there is data acquisition, remote meter reading, the warning of multiplexing electric abnormality information, electric energy quality monitoring, line loss analyzing and load monitoring management function.Electricity consumption situation can be understood at any time by this cover system for, electricity consumption both sides, utilize the step price in " Pinggu, peak ", formulate, arrange rational power program, control fault outage rate, reduce line loss, reach technical energy saving, increase the object of economic benefit.
As terminal collector---the intelligent electric energy meter of intelligent grid, adopt can carry out the perfect in shape and function of GPRS wireless information transfer can realize the high-precision intelligent ammeter that electric company and user carry out two-way communication.In the measuring apparatus of reality, it is minimum that its error can be adjusted to error by the error Yb except intelligent electric energy meter under load point, and it is all relevant with the operational factor of actual secondary circuit that error is put in other metering.According to the error of electric current, voltage transformer (VT), reasonable combination is matched, and makes mutual inductor resultant error little as far as possible.Pair principle is that the ratio symbol of adapted current transformer and voltage transformer (VT) is as far as possible contrary, and equal and opposite in direction, angular difference symbol is identical, equal and opposite in direction.Like this, the resultant error of mutual inductor can be ignored substantially, only need adjust according to the error of transformer secondary voltage drop tolerance fit electric energy meter own, just can reduce measuring apparatus composition error to greatest extent.
This beneficial effect of the invention is: apparatus of the present invention, distributed way can be adopted to be configured, realize more excellent resource distribution, and the accuracy rate of load prediction, line loss prediction can be improved, and can Long-distance Control be realized, when system is under electricity condition is protected in releasing, can direct remote terminal user be passed through, realize distant place switching on; Or pre-set power definite value, electricity definite value, the moon purchase of electricity etc. realize that power controls respectively, the moon electricity control, purchase of electricity controls.In addition, fault analysis foundation can also be provided, realize the on-line analysis of abnormality, dynamically follow the tracks of and automatically control, improve power supply reliability, realize the monitoring of electrical network components and parts, intelligent electric energy meter and subscriber equipment, prevention, maintenance.The electrographic recording of inquiry exception can be passed through, for fault analysis provides reliable real time data after fault occurs.
