The small hydropower station control system comprises a master site arranged in a power dispatching center and slave sites arranged on various small hydropower stations. Each slave site comprises a data acquisition device and a Beidou satellite user machine, the master site comprises an information management platform and a Beidou satellite command aircraft, and bidirectional communication is achieved between the information management platform and the data acquisition devices sequentially through the Beidou satellite command aircraft, a Beidou satellite and the Beidou satellite user machine. A Beidou communication technology enables the bidirectional communication to be carried out, and safety of data can be guaranteed; the information management platform carries out comprehensive management on the small hydropower stations according to received information of the small hydropower stations of the various slave sites, power grid load flow distribution is optimized, loss of a power grid is reduced, and the effects of energy conservation and emission reduction are achieved.
Description
Technical field
The present invention relates to power system of data acquisition and communication technical field, particularly a kind of small hydropower station control system.
Background technology
At present, according to the advantage of some local landform, can build a lot of small hydropower stations.With regard to Huangshan, the small hydropower station moved has reached up to a hundred, these small power generation enterprise automation equipment and communication network great majority are not very sound, majority does not possess the condition of communicating by letter with power-management centre, the real-time information of these small hydropower stations all can't be uploaded mostly, can't monitor in real time.In order to strengthen the management to these small hydropower stations, be badly in need of a kind ofly can possessing bi-directional communication function and the safer reliable system of communicating by letter, reach the purpose to each Hydropower Plants Real-time Monitoring.
Summary of the invention
The object of the present invention is to provide a kind of small hydropower station control system, improve the operation and management level of small hydropower station, optimize electric network swim and distribute.
For realizing above purpose, the technical solution used in the present invention is: a kind of small hydropower station control system, comprise the home site that is arranged on power-management centre, the substation point that is arranged on each small hydropower station, described substation point comprises data collector and big-dipper satellite subscriber computer, home site comprises information management platform and big-dipper satellite commander machine, and information management platform commands machine, big-dipper satellite, big-dipper satellite subscriber computer and data collector to carry out two-way communication by big-dipper satellite successively.
Compared with prior art, there is following technique effect in the present invention: the Big Dipper communication technology can be carried out two-way communication, and the security performance of data accesses guarantee; Information management platform, according to the small hydropower station information of each substation point received, carries out integrated management to small hydropower station, optimizes electric network swim and distributes, and reduces grid loss, plays the effect of energy-saving and emission-reduction.
The accompanying drawing explanation
Fig. 1 is theory diagram of the present invention.
Embodiment
Below in conjunction with Fig. 1, the present invention is done and is described in further detail.
Consult Fig. 1, a kind of small hydropower station control system, comprise the substation point 10 that is arranged on each small hydropower station, the home site 20 that is arranged on power-management centre, only illustrated a sub-website 10 in figure, actually should in each small hydropower station, be provided with a sub-website 10.Described substation point 10 comprises data collector 11 and big-dipper satellite subscriber computer 12, home site 20 comprises information management platform 21 and big-dipper satellite commander machine 22, between data collector 11 and big-dipper satellite subscriber computer 12, by the RS-422 telecommunication cable, connect, information management platform 21 also is connected by the RS-422 telecommunication cable with big-dipper satellite commander machine 22.Information management platform 21 commands machine 22, big-dipper satellite 30, big-dipper satellite subscriber computer 12 to carry out two-way communication with data collector 11 by big-dipper satellite successively.The various information of the small hydropower station that the big-dipper satellite subscriber computer 12 of each small hydropower station collects data collector 11 upload to home site, home site carries out analyzing and processing according to the information received, reach the real-time supervisory function bit to each small hydropower station, simultaneously, can also send instruction to each small hydropower station.It is pointed out that and use Beidou satellite system to carry out communication here and do not use GPS, is because GPS does not possess bi-directional communication function, and there is potential safety hazard in GPS transmission key message.
As preferred version of the present invention, described data collector 11 comprises intelligent kilowatt-hour meter 113 and the processor 114 of the critical point information about power of the remote terminal control module 111 of the analog data that gathers small hydropower station, the switching value acquisition module 112 that gathers the switching value signal of small hydropower station, collection small hydropower station, and processor 114 receives described each information and also with big-dipper satellite subscriber computer 12, carries out two-way communication.Described substation point 10 also comprises display 13, storer 14, and described display 13, storer 14 all are connected with processor 114.It is job informations that the staff that facilitates each substation point 10 also can this website of real-time monitored that substation point 10 arranges display 13 and storer 14, if the substation point itself just is provided with the equipment of being observed, does not need display 13.
When real work, remote terminal control module 111 transfers to processor 114 by remote measurement amounts such as the set end voltage of generator, electric current, active power, reactive power, power factor (PF) and water levels and carries out pre-service; The switching value acquisition module 112 remote signalling amounts such as interior switch, disconnecting link of standing are also delivered to processor 114; Intelligent kilowatt-hour meter 113 is pressed the internal communication protocol using encapsulation by critical point, generating plant information about power, by the physical communication port, in intercommunicating mode, packaging information is sent to processor 114.Processor 114 will move after the upper time service sign of generator terminal voltage, electric current, active power, reactive power and critical point, generating plant electric weight mark as follows: 1, be stored in storer 14; 2, information is presented on display 13; 3, by with the data of time service sign, mark id information and the geographical location information sign of big-dipper satellite subscriber computer 12 simultaneously, by big-dipper satellite subscriber computer 12, this information exchange is crossed to big-dipper satellite 30 and send big-dipper satellite commander machine 22 to.Big-dipper satellite commander machine 22 is downloaded and is sent to information management platform 21 by these data and processed.After information management platform 21 process informations, send as required instruction to each substation point.
Small hydropower station can cause power failure because of partly cause, now can cause substation point 10 to quit work, just the have no way of finding out about it working condition of power failure substation point 10 of home site 20.Therefore, described substation point 10 also comprises super capacitor 15, super capacitor 15 is for substation point 10 provides back-up source, and after maintaining substation and putting 10 dead electricity, system still can work a period of time, makes substation point 10 in time dead electricity warning message in station to be uploaded to home site.
