Abstract
A small hydropower station operation data and electricity consumption information acquisition and access system relates to an electricity consumption information acquisition and access system. The small hydropower station information data acquisition system cannot take cost, stability and speed into consideration at the same time. The small hydropower station operation data and electricity consumption information acquisition and access system comprises electricity meters, wireless communication modules, a pre-server and a Web server, and is characterized in that: the small hydropower station operation data and electricity consumption information acquisition and access system also comprises acquisition workstations, servers and optoelectronic isolators, the acquisition workstations obtain the electricity meter data information of the pre-server via the Web server, and after being stored in the databases of the servers and normalized, the information obtained by the acquisition workstations accesses a dispatch-automating master station pre-system via the optoelectronic isolators. The technical scheme does not need the construction of power line carrier communication or optical cables, so that the cost is reduced, meanwhile, the reliability of operation and the requirement on response time are guaranteed, on the other hand, since the acquisition workstations respectively independently acquire the operation data of each small hydropower station at different times, the security of data is enhanced, and the integrity of data cannot be affected when any acquisition workstation goes wrong.
Description
Technical field
The utility model relates to a kind of power information and gathers connecting system.
Background technology
At present, small power station's aboundresources, small power station determines whether generate electricity by the power station usually according to coming the regimen condition.Scheduling is difficult to predict the situation of exerting oneself of small hydropower station, just adopts the method for estimation or multiplying factor to estimate a numeral at present.And dispatching of power netwoks, load prediction, load day are surveyed, terminal voltage detects, idle and voltage management, Ying Feng cross the summer, cross tea, cross the winter, statistical report form etc. is produced in scheduling, all needs to use plant generator information.
Therefore, press for and implement small hydropower station information data acquisition system, monitoring power station operation information improves dispatching of power netwoks and operation of power networks management level.
Traditional transformer station/power house dispatching automation main website access way is mainly by SDH, PCM equipment, insert main station system by the optical cable transmission, but the investment of individual website disposable apparatus is big, and small hydropower station is distributed in mostly among the remote mountains, have inconvenient traffic, more XXL the expense of optical cable laying.Or adopt mode such as power line carrier, PLC to insert, but the power line carrier, PLC mode is received and is difficult for long-term stable operation factor affecting such as electrical network framework.
The utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is that the prior art scheme is improved and improved, provide small power station's service data power information to gather connecting system, to reach low-cost aim of stable operation under the prerequisite that guarantees picking rate.For this reason, the utility model is taked following technical scheme.
Small power station's service data power information is gathered connecting system, the ammeter that comprises record small hydropower station working condition, the wireless communication module that is used for transmission ammeter data information, be used for gathering the front server of ammeter data information, the web server that links to each other with front server, it is characterized in that: also comprise a plurality of acquisition workstations that link to each other with the web server, two servers of being equipped with of heat each other, photoisolator, acquisition workstation obtains the ammeter data information of front server by the web server, the information that acquisition workstation obtains by server data library storage and the processing of data stipulations by photoisolator access dispatching robotization main website front-end system.Because power information acquisition system safety factor, open database interface not, therefore, small power station's service data is obtained the mode by routine nesting IE plug-in unit, obtain small power station's service data but more owing to small hydropower station quantity with the inquiry of web webpage, it is slower that the data of web data query mode are obtained speed, and the data acquisition front-end system adopts distributed preposition layout, adopt the collection of many acquisition workstation subregion bursts, to improve the overall data acquisition speed.The small power station's service data that collects is focused in the server, carry out passing through the RS232 port after database storage, the processing of DISA stipulations, through optical isolation, system of access dispatching robotization main website analog channel cabinet.The dispatching automation main station system with a whole set of small power station service data acquisition system as a substation, the data message that therefrom obtains is handled, obtain small power station's service data, be presented in the dispatching automation main station system, it as important Data Source, is applied to each functional module in the various systems.Acquisition workstation quantity is looked Data Update time requirement, small hydropower station quantity is determined.The technical program needn't be set up power line carrier, PLC or optical cable, reduces cost, and guarantees the reliability of work and the time requirement of response simultaneously.Many acquisition workstations carry out independent acquisition time to each small power station's service data respectively on the other hand, improve the security of data, and the fault of any acquisition workstation can not influence the integrality of data.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature.
Described acquisition workstation links to each other with server by network, and server links to each other with dispatching automation main website front-end system by the RS232 interface.Server with the DISA/CDT stipulations, is forwarded to dispatching automation main website front-end system by the RS232 interface by with the processing of data stipulations.As a system of access dispatching robotization main website of transformer station, server monitors the total system operating condition by visualization interface with whole power information acquisition system in system.
Described wireless communication module links to each other with front server by GPRS.The power information acquisition system adopts GPRS technology (General Packet Radio Service, general packet radio service technology), utilizes mobile data services, has realized the timing acquiring storage of data such as small hydropower station is meritorious, idle and inquires about.Realize the small hydropower station data on send and store.Its reliable operation, cost are low, and guarantee the time requirement of sampling.
Beneficial effect: the technical program needn't be set up power line carrier, PLC or optical cable, reduces cost, and guarantees the reliability of work and the time requirement of response simultaneously.Many acquisition workstations carry out independent acquisition time to each small power station's service data respectively on the other hand, improve the security of data, and the fault of any acquisition workstation can not influence the integrality of data.
