Utility model content
The purpose of this utility model is to provide a kind of power station control system based on the Big Dipper communication technology, improves the operation and management level of small hydropower station, optimizes electric network swim and distributes.
For realizing above object, the technical solution adopted in the utility model is: a kind of power station control system based on the Big Dipper communication technology, comprise be arranged on power-management centre home site, be arranged on the substation point of 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 utility model: 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 receiving, 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.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail.
Consult Fig. 1, a kind of power station control system based on the Big Dipper communication technology, comprise be arranged on each small hydropower station substation point 10, be arranged on the home site 20 of power-management centre, in figure, only illustrate a sub-website 10, 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 RS-422 telecommunication cable, connect, information management platform 21 is also connected by 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 receiving, reach the real-time supervisory function bit to each small hydropower station, meanwhile, 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 GPS transmission key message exists potential safety hazard.
As preferred version of the present utility model, 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 carries out two-way communication with big-dipper satellite subscriber computer 12.Described substation point 10 also comprises display 13, storer 14, and described display 13, storer 14 are all 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 substation point itself is just provided with the equipment of observing, 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; Switching value acquisition module 112 is also delivered to processor 114 by the remote signalling such as switch, disconnecting link amount in station; Intelligent kilowatt-hour meter 113 is pressed internal communication protocol using encapsulation by critical point, generating plant information about power, by 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 mark id information and the geographical location information sign of big-dipper satellite subscriber computer 12 with the data of time service sign 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 processes.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.
