Description
Technical field
The invention belongs to the electrical management field, relate in particular to a kind of electric weight computing method, device and ammeter opertaing device.
Background technology
Along with the accumulating over a long period of huge, the electric quantity data of power consumer quantity, with the change of power device in the electric process, the change of subscriber data, cause when systematic analysis is calculated and inquire about, can count the result efficiently, in time, exactly, become a basic ground, urgent problem.This also is each Utilities Electric Co. special problem of being concerned about in management.
Meanwhile, along with the develop rapidly of the communication technology, also lay a good foundation for the management of electric power demand side.GPRS (General Packet Radio Service) (the General Packet Radio Service that China Mobile releases, GPRS) and the CDMA of CHINAUNICOM (Code Division Multiple Access, CDMA) business has real-time online, wide coverage, cheap, the high reliability features of expense, electric power enterprise can utilize the advantage of GPRS/CDMA public communication network to overcome the shortcoming of conventional channels in the past, build with wireless public network be main telecommunication media, in conjunction with the open communication network of multiple communication mode.Foundation is based on the data center of electric energy data, and realize functions such as electric weight clearing, electrical energy consumption analysis, line loss analyzing, distribution transformer monitoring, load management on this basis, power consuming administrative system based on this, can improve the management and the operation level of Utilities Electric Co. after putting into operation greatly, stop swindle and electricity filching behavior, for improving the service quality of electric power enterprise, the economic benefit of enterprises that increases electric power provides technical guarantee.
In the prior art of recent development, utilize GPRS to unite the data transmit-receive function of net or WCDMA net, on corresponding ammeter, insert the managing electric quantity terminal, can gather the service data of ammeter in real time, can realize long-range distribution transforming monitoring, and realize functions such as running status demonstration, abnormal information warning, Power Quality Detection, line loss analyzing, load management, remote meter reading, the equilibrium analysis of circuit electric weight, customer service.The realization of these functions depends on quick, the accurately calculating of electric weight.The accurate calculating of electric weight must be considered the change of user in the power business operation that is taken place with the electric process amount of falling into a trap device.
Enumerate explanation below respectively:
Change table: refer to the operation that electric industry metrological service changes the watt-hour meter of operation for a certain reason, may produce when changing table and remedy electric weight.The table of this ammeter ends sign indicating number and changes after changing table, should note changing table that table handling brings and end sign indicating number and change when carrying out the electric weight statistics, changes the expression condition and then should carry out the segmentation statistics to electric weight in the timing statistics scope if exist.In changing table, note the table time of changing, old table and end that sign indicating number, new table are minimum, the information such as electric weight, old table address, new table address of remedying are used in order to the main website software analysis.
Change voltage current transformer: the replacing voltage current transformer causes calculating stoichiometric point voltage, electric current one sub-value changes with the ratio of two sub-values, directly influences various electric power calculated values.
Change the ammeter direction of current: can adjust because of the electric current of certain reason ammeter inserts direction, user's electricity consumption direction can change.
Bypass is for confession: refer to the situation that electric industry department replaces a certain working line of same voltage registration in the transformer station to power by the by-pass line of the different voltages registrations of transformer station under specific condition.When calculating electric weight, bypass is not carried out electric weight calculating as an independent circuit, and the electric weight that has its to produce will be separated to each quilt for calculating in the circuit.Bypass happens occasionally for supplying, and time length is uncertain, and concrete generation has the system manager to carry out manual typing for information, entry information comprises that bypass, bypass are for the road, in generation,, in generation, carried out can carrying out corresponding calculated according to entry information when electric weight calculates for the concluding time for the start time.
Remedy electric weight: because the power consumption that cause specific gauging table meter can't metering user in certain period, electric industry metrological service will manually remedy so, and the electric weight of benefit is called remedies electric weight.Change in the table process or watt-hour meter might be remedied when breaking down.
To above situation, system must provide the associated databases table, and a situation arises gives record to each pen.Calculate certain user's the interior electric weight of section sometime, must consider whether above operation took place therebetween.Can know that according to this calculating each time must be inquired about above-mentioned each database table, also will bring the prolongation greatly of computing time.Especially along with the electricity consumption number of users, image data quantity, when various operation note quantity all rises to certain degree, make the time of calculating an electric weight all more than several seconds, the suchlike operations that relate to a large amount of calculating such as electrical energy consumption analysis, line loss analyzing obviously will just can be finished in the long-term time.
