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 and development of intelligent grid divides three phases progressively to carry out, to build up to the year two thousand twenty comprehensively, intelligent power link wherein mainly comprises the aspects such as the applying of intelligent electric energy meter, the application of collecting terminal, the construction of power information acquisition system, finally realizes the target of power information collection " all standing, entirely to gather, control in full ".
All standing is exactly all kinds of power consumers that power information acquisition system will cover in Utilities Electric Co.'s operation region.Full collection will realize remote automatic acquisition to the power information of all kinds of stoichiometric points that power information acquisition system covers exactly.Control in full is exactly the electricity consumption situation of power user power consumption information acquisition system energy continuous acquisition user, calculate the amount of its residue electricity charge and be shown to user, the prompting subscriber payment when remaining the electricity charge and being few, remain the electricity charge lower than setting amount time perform power purchase tripping operation control, user complete payment after system command electric energy meter close a floodgate reply power supply.Realizing above target just must overall application intelligent electric energy meter: for the intelligent electric energy meter that should adopt and possess expense control function that Adds User; The power supply area of expense control function electric energy meter is not possessed to original use or intelligent electric energy meter transformation must be carried out in place, 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 major part adopts wireless public network (GPRS/CDMA) mode, and wireless public network investment is little, and applied range, networking flexibility, adaptability are good, reliability is higher.Collecting device layer is made up 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.What down going channel (communication channel of terminal and electric energy meter) was conventional has 2 kinds of modes: one is that acquisition terminal is by 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 is arranged according to main website and the time interval gather the information such as the electricity of electric energy meter, and the power information that the order of checking meter receiving main website is measured by each electric energy meter is sent to main website.The electricity collected then is counted as the electricity charge by main website layer, then compares with the situation of paying dues of power consumer, calculates the dump energy of this user.Remain the electricity charge few time prompting user pay the electricity charge, remain the electricity charge lower than setting amount time perform power purchase tripping operation control, user complete payment after system command electric energy meter close a floodgate restore electricity.
Because power information acquisition system relates to the charge calculation of huge numbers of families, relate to and can correctly notify to pay tariff by defaulting subscriber, stop the electric power supply of defaulting subscriber exactly, reliably recovered the electric power supply of payment user in time, each appliances therefore entering the use of power information acquisition system all must carry out the reliability and stability test of function, performance, technical indicator.
Existing power information collecting test device can only complete the test gathering down going channel from concentrator (terminal) to electric energy meter; Because do not test with main website, so cannot carry out from concentrator (terminal) to the performance test of main website.If carry out testing with the main website run, following deficiency can be produced:
1. test process needs to build a hundreds of Virtual User, also will complete the overall process of each operation flow, because test will simulate various operating mode, will produce a large amount of junk data, thus affect the operation of formal system in formal system.
2. under formal environments, carry out simulation expense control breaker tripping and closing test, likely cause normal electricity consumption resident mistakenly stop electricity, affect the normal life of huge numbers of families, and may Social Public Feelings be produced.
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 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 of various interference source, frequency conversion load and distribution net work structure can be simulated, each alanysis, research, test condition are provided; Emulation platform has test, statistics, analytic function; Emulation platform can not affect the normal electricity consumption of power consumer when testing, can not produce junk data in formal environments.
Summary of the invention
The object of the invention is, according to the deficiency that existing power information acquisition system exists, the present invention proposes a kind of power information gathering simulation test platform.
Power information gathering simulation test platform of the present invention is a power information acquisition system comprising test environment emulation module and test statistics analysis module.It can the power information acquisition system of the formal production run of the existing input of analog simulation, for properties, the Function detection of carrying out system provides platform and tested object.
Power information gathering simulation test platform of the present invention is on the basis of existing power information acquisition system, (the main station system software of emulation platform and the system software of commencement of commercial operation are on all four in main functionality), adopt different runtime servers, the extreme slogan in IP address is different.Original platform adds the controlling functions of test emulation module, adds the analytic function of test statistics result.
Power information gathering simulation test platform of the present invention needs artificial site actual, because the master data of power information acquisition system is from Electric Power Marketing System, therefore just must with Electric Power Marketing System interface; Expense Ore-controlling Role according to gather electricity carry out charge calculation, the control of power consumer energy charge be realized, just must with take Ore-controlling Role interface.Therefore power information gathering simulation test platform of the present invention also establishes power marketing analogue system and expense control analogue system.Interface mode between power information gathering simulation test platform and this two systems is: Real-time data interface is realized by middle database and Webservice mode; Non-real-time data interface is realized by data center's mode.Real time data between system realizes mutual by the Webservice interface mode of data center, and non-real-time data is published to the middle database of data center by ETL mode, is responsible for the data of middle database to send other system to by data center.
