Description
technical field
The present invention relates to power information gathering simulation test platform, belong to electric-power metering technical field.
Background technology
According to national intelligent grid construction plan, the construction of intelligent grid and a development minute three phases progressively carry out, to the year two thousand twenty, will build up comprehensively, intelligent power link wherein mainly comprises the applying of intelligent electric energy meter, the application of collecting terminal, the aspects such as construction of power information acquisition system, finally realizes the target of power information collection " all standing, entirely gather, control in full ".
All standing is exactly that power information acquisition system will cover all kinds of power consumers in Utilities Electric Co.'s operation region.The power information of all kinds of stoichiometric points that full collection will cover power information acquisition system exactly realizes remote automatic acquisition.Control in full is exactly power consumer power information acquisition system energy continuous acquisition user's electricity consumption situation, calculate the amount of its residue electricity charge and be shown to user, when the residue electricity charge are few, point out subscriber payment, in the residue electricity charge, carry out power purchase tripping operation when setting amount and control, user complete pay the fees after system command electric energy meter close a floodgate and reply power supply.Realizing above target just must overall application intelligent electric energy meter: for Adding User, should adopt the intelligent electric energy meter that possesses expense control function; Intelligent electric energy meter transformation must be carried out in the power supply area or the place that original use are not possessed to expense control function electric energy meter, original electric energy meter is replaced by the intelligent electric energy meter with expense control function.
Power information acquisition system is logically divided into main website layer, communication channel layer, collecting device layer.Main website is the administrative center of system, manages system-wide data processing, market demand and sends collection, expense control breaker tripping and closing order; The major way of telecommunication passage has optical fiber communication, 230MHz radio communication, wireless public network communication, medium voltage electricity line carrier communication etc.Current most of wireless public network (GPRS/CDMA) mode that adopts, wireless public network investment is little, applied range, networking flexibility, adaptability is good, reliability is higher.Collecting device layer is comprised of terminal, collector and intelligent electric energy meter.During communication, main website is by remote channel and terminal called, and terminal is again by down going channel and intelligent electric energy meter communication.Down going channel (communication channel of terminal and electric energy meter) is conventional 2 kinds of modes: a kind of is that acquisition terminal passes through power transmission line low-voltage power carrier and intelligent electric energy meter communication; The second be acquisition terminal by power carrier and collector communication, collector carries out communication by RS-485 and electric energy meter again.
The acquisition time that during operation, acquisition layer arranges according to main website and the time interval gather the information such as electric weight of electric energy meter, and the power information that the order of checking meter of receiving main website is about to each electric energy meter metering sends to main website.Main website layer is counted as the electricity charge by the electric weight collecting, then compares with the situation of paying dues of power consumer, calculates this user's dump energy.In the residue electricity charge, point out user to pay the electricity charge when few, in the residue electricity charge, carry out power purchase tripping operation when setting amount and control, user complete pay the fees after system command electric energy meter close a floodgate and restore electricity.
Because power information acquisition system relates to huge numbers of families' charge calculation, relate to can correctly notify soon and pay tariff on defaulting subscriber, stop exactly defaulting subscriber's electric power supply, has recovered reliably in time to pay the fees user's electric power supply, therefore enters the reliability and stability that each appliances that power information acquisition system used all must carry out function, performance, technical indicator and tests.
Existing power information collecting test device can only complete the test that gathers down going channel from concentrator (terminal) to electric energy meter; Because test main website not, so the performance test from concentrator (terminal) to main website cannot be carried out.If test and can produce following deficiency with the main website moving:
1. test process need to be built a hundreds of Virtual User, also will complete the overall process of each operation flow, because test will be simulated various operating modes, will in formal system, produce a large amount of junk datas, thereby affect the operation of formal system.
2. under formal environments, simulate expense control breaker tripping and closing test, likely cause normal electricity consumption resident mistakenly stop electricity, affect huge numbers of families' normal life, and may produce Social Public Feelings.
For this situation, the present invention proposes a kind of brand-new thinking: design a kind of power information acquisition system simulation test platform, can analog simulation and replace the power information acquisition system of the formal production run of existing input to carry out properties, the Function detection of system; The on-the-spot actual condition that can simulate various interference sources, frequency conversion load and distribution net work structure, provides each alanysis, research, test condition; Emulation platform has test, statistics, analytic function; Emulation platform can not affect the normal electricity consumption of power consumer when testing, and can not produce junk data in formal environments.
summary of the invention
