Embodiment
Below through specific embodiment the technical scheme of the utility model is done further explanation.
1, hardware designs.
The starting point that the utility model is created is exactly on the basis of Hardware configuration that does not change the traditional protection device and software arrangements, makes device Rapid Realization IEC61850 communication function.In order to improve the utility model operational reliability and stability, the utility model has adopted two CPU mode of operations, promptly protects CPU board and MMS communication board.The protection CPU board is responsible for the collection protective current specially and voltage is protected computing, tripping operation control; MMS communication cpu plate then is responsible for IEC61850 communication specially.
32 arm processors of STR912 that the protection CPU board of the utility model adopts, 2 AD7656 high-precision AD sampling A, 240*128 Chinese display liquid crystal display.1 road RS232 communication interface (Transistor-Transistor Logic level does not go out cabinet, carries out information exchange with the MMS communication board) externally is provided.And 4 road Transistor-Transistor Logic level output interfaces are provided, are used for transmitting tripping operation information to the MMS communication board.
The MMS communication board of the utility model then adopts 32 high-performance arm processors of AT91SAM9260,200MHz dominant frequency, 64M RAM, 8M Flash.The MMS communication board externally provides 3 road Ethernet interfaces (photoelectricity is optional); 1 road IRIG-B to the time interface; 1 road RS232 debug serial port; And 4 road Transistor-Transistor Logic level input interfaces, the fast trip signal that receives self-shield CPU to transmit, the MMS communication board sends the GOOSE trip signal through the GOOSE network interface to on-off controller.
2, software design.
Because the utility model adopts two cpu models, the protection CPU board is different with the task that the MMS communication board is responsible for.So the utility model adopts ucOSII and two kinds of more popular operating systems of industry of Linux.These two kinds of operating systems have his own strong points, and protection CPU adopts real-time ucOSII embedded OS, can effectively bring into play the real-time of ucOSII, improves the action real-time of protective device; And the MMS communication board mainly is responsible for the IEC61850 communication task, so selected the powerful built-in Linux operating system of network function for use.
The MMS communication board of the utility model has adopted built-in Linux operating system, adopts the Ramdisk technology that the RAM designated space is invented magnetic disc store, and the back device that powers on copies to the Ramdisk file system among the RAM and decompress(ion) forms the root file system of Linux.Because the Ramdisk file system is read-only,, improved the operation stability of device so the Ramdisk technology can guarantee that under any circumstance operating system is never collapsed.
The MMS communication board of the utility model obtains the signal of slow variation through serial mode from the protection CPU board, like analog quantity, definite value, pressing plate state, electric degree data etc., and communicates through IEC61850 agreement and the IEC61850 client based on MMS.After the utility model powers on the model of device is resolved, and start the IEC61850 server, wait for the connection of client software; After client software and device successful connection; All reports to device enable, and always call all data of deriving means.Whether the content of installing the data set that quick scanning respectively reports controll block changes, if change then trigger report immediately, sends report to client.
The utility model is following for the GOOSE quick displacement Signal Processing mode that trips; CPU board then directly sends the MMS plate to through Transistor-Transistor Logic level; If detecting level, the MMS plate changes; Then outwards send the GOOSE trip signal immediately, this level transmissions mode has shortened the time of delay of GOOSE tripping operation greatly, guarantees that on-off controller can reliable quick acting.
The utility model adopt two kinds of SNTP and IRIG-B to the time mode guarantee device clock with station clock is synchronous entirely.
The SNTP networking to the time mode adopted the communication technology based on Ethernet UDP; Device is regularly to clock server request clock synchronization; After clock server receives the request of device, will stab the reference time, original time stabs, accept timestamp, delivery time sends device together to, device calculates the network delay time according to these 4 timestamps; Thereby clock is finely tuned, reach the purpose of clock synchronization.IRIG-B to the time mode then be by clock server regularly 1 second to each device send once to the time signal; To the time comprised absolute time in the signal; Device adopt CPLD to the IRIG-B input to the time level scan fast; When detect to the time during signal, then the IRIG-B sequential is decoded, thereby obtains current correct time.
Though the utility model with preferred embodiment openly as above; But they are not to be used for limiting the utility model; Anyly have the knack of this art; In spirit that does not break away from the utility model and scope, certainly when can doing various variations or retouching, so being as the criterion of should being defined with the application's claim protection range of the protection range of the utility model.
