Abstract
The utility model discloses a key communication based switch controller which comprises a power acquisition unit, a relay protection unit, a master control unit, a communication module and an encryption module. When power line failure occurs, the master control unit controls the relay protection unit to enforce relay protection and sends a failure state signal to the encryption module, and the encryption module encrypts the failure state signal and sends the signal to the communication module to be sent outwardly. Before the master control unit sends the signal outwardly, the signal is firstly encrypted, and after encryption, data can be protected from being checked and modified. In addition, a safe communication mode can be provided for an originally-unsafe channel. On one hand, even if the data is intercepted and captured, it is hard to acquire data information; and on the other hand, it can be ensured that data received by a distant automatic control system is reliable and credible. The automatic control system can complete distribution network automated scheduling based on the encrypted data, and maloperation will not happen.
Description
Technical field
The utility model relates to the on-off controller in the electric power system.
Background technology
Current society is the information age, and along with the fast development of information technology, the intellectuality of power industry is more and more higher to the requirement of communication, for information maintain secrecy and the fail safe of system still is important, corresponding strick precaution solution must be arranged.Present on-off controller all is directly to send when outwards transmitting data, and this data are easy to be pretended to be by the third party or change, and cause concerning security matters or the misoperation of information, and the reliability of system is difficult to be protected.
Summary of the invention
At the problems referred to above; the utility model provides a kind of on-off controller based on secret key communication; not only can realize at present required alternate protection with ground protection but also solve at present owing to communicate by letter unreliablely can not doing four distant problems, and upload the data to the power supply administration backstage and realize that four is distant: the scheduling of remote signalling, remote measurement, remote control, remote regulating realization distribution automation.
The utility model is that the technical scheme that its technical problem of solution adopts is:
On-off controller based on secret key communication comprises: the electric quantity acquisition unit, and the test side of electric quantity acquisition unit is connected to power line; Be used for realizing the relaying protection unit of relaying protection function, the output of electric quantity acquisition unit is connected with the relaying protection unit; Main control unit, main control unit are connected and handle the protection logic of relaying protection unit with the relaying protection unit, it is provided with signal sending end; Communication module and encrypting module, the signal sending end of main control unit is connected with communication module by encrypting module.When power line failure took place, relaying protection was implemented in main control unit control relaying protection unit, and fault status signal is sent to encrypting module, delivers to communication module after encrypting module is encrypted fault status signal and outwards sends.
Wherein, described electric quantity acquisition unit comprises three phase current mutual inductors and a line voltage transformer, and the primary side of phase current mutual inductor and line voltage transformer is arranged on the power line, and secondary side is connected with the relaying protection unit.
Described communication module comprises or several in GPRS module, GSM SMS module, ethernet interface module, the fiber interface module.
The beneficial effects of the utility model are: the utility model is encrypted earlier when main control unit outwards sends signal; can help protected data not checked and revise after the encryption; and can help provides the safe communication mode at this unsafe channel; even these data are intercepted and captured and also are difficult to obtain data message on the one hand; can guarantee that on the other hand the data that the automation control system in a distant place receives are reliable and believable; automation control system can be finished scheduling to distribution automation based on these ciphered data, misoperation can not occur.
Description of drawings
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is that system of the present utility model forms schematic diagram.
Embodiment
With reference to Fig. 1, on-off controller of the present utility model comprises electric quantity acquisition unit 1, relaying protection unit, main control unit 3, communication module 4 and encrypting module 5.In addition, on-off controller can also further be provided with man-machine interaction unit etc., makes things convenient for the user that on-off controller is carried out execute-in-place.
Electric quantity acquisition unit 1 is used for the various electric weight of electric power system are detected; its test side is set directly on the power line; particularly; electric quantity acquisition unit 1 can comprise three phase current mutual inductors and a line voltage transformer; the primary side of phase current mutual inductor and line voltage transformer is arranged on the power line, and secondary side is connected with relaying protection unit 2.The electric quantity data that electric quantity acquisition unit 1 collects is sent into relaying protection unit 2, sends into main control unit 3 after the 2 pairs of data in relaying protection unit are handled and carries out analyzing and processing.Main control unit 3 is controlled relaying protection unit 2 based on the result that analyzing and processing obtains, and makes relaying protection unit 2 realize immediately protecting on the spot when fault takes place.
When power line failure took place, main control unit 3 was implemented relaying protection except control relaying protection unit, also fault status signal outwards can be sent, and generally sends to the power supply administration backstage.The utility model sends to encrypting module 4 with fault status signal, delivers to communication module 5 after encrypting module is encrypted fault status signal and outwards sends.Arranging of encrypting module 5 can be guaranteed maintaining secrecy of data.The cipher mode that this encrypting module 5 adopts can utilize existing various data encryption technology to realize.These data encrypted send to the power supply administration backstage, obtain the fault status information of corresponding on-off controller after decipher it on the backstage, realize the scheduling of distribution automation then.Encryption can reach following purpose: confidentiality helps protection user's sign or data not to be read; Data integrity: help protected data not change; Authentication: guarantee that data are from a specific side.
In different embodiment, communication module 5 can realize in different ways, for example or several in GPRS module, GSM SMS module, ethernet interface module, the fiber interface module.
Execution mode of the present utility model is not restricted to the described embodiments, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection range of the present utility model.
