Detailed description of the invention
Fig. 1 is that site protective relaying device is based on 61850 models and with remote management unit interacts schematic diagram；
Fig. 2 is the flow chart of the method for the present invention.
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
Transformer substation system is divided into three station level, wall and process layer levels by IEC61850 standard.In the prior art,
Network between site protective relaying device (may be simply referred to as protective device) and intelligent management unit (may be simply referred to as administrative unit)
Communication is based on IEC61850 standard.Protective device establishes corresponding 61850 model in ICD file, and ICD model file is imported
Site protective device, 61850 servers in opening protecting apparatus, while intelligent management unit gatherer ICD model, starting
61850 clients in administrative unit, site protective relaying device can be communicated with administrative unit by station level mobile agent server protocol
A kind of site protective device based on 61850 of the invention outputs drive method, as shown in Fig. 2, including as follows
Step S1 is based on 61850 standards to site protective device in the ICD model file of site protective device
It is modeled, the data set for describing entitled " outputing transmission ", each FCDA in data set is established at logical device " MGR "
It is outputed for one, outputs and modeled according to the DO type that CDC is SPC, while establishing the transmission of outputing that CDC is SPC and enabling
It is enabled included in " outputing transmission " data set to output transmission, entirely outputs whether transmission enables for controlling, opens
When to be driven enabled state out be " investment " (may be defined as numerical value 1), device can carry out outputing transmission operation, for " exiting "
When (may be defined as numerical value 0), device refusal outputs transmission operation.Although outputing transmission and outputing the enabled the two of transmission is DO class
Type when definition, is outputed the enabled and common transmission of outputing of transmission and is distinguished by respective title.
Step S2 by ICD model file tripping in site protective device, and is imported into intelligent management unit, and intelligence is managed
Unit resolves ICD model file is managed, all FCDA points in " outputing transmission " data set are read, generation institute is in need to output transmission
DO and output the enabled DO of transmission.
Step S3, intelligent management unit is sent by 61850 to be read service commands and reads to protective device to output transmission and make
Device after protective device receives read command, is outputed the enabled real-time status of transmission and is sent to administrative unit by energy state；Equally,
Administrative unit by 61850 send read service commands read maintenance to protective device pressing plate state (maintenance pressing plate state include
" exiting " and " investment "), after protective device receives read command, the real-time status of turnaround of unit pressing plate is sent to administrative unit；
Finally, administrative unit, which is read, outputs all real-time status for outputing transmission DO in transmission data set.
Step S4, if the maintenance pressing plate for obtaining device is in the state that exits, administrative unit sends investment maintenance to device
Pressing plate order, device are investment state according to setting turnaround of unit pressing plate is ordered, if outputing enabled be in of transmission exits state,
Administrative unit sends the enabled order of investment transmission to device, and device is outputed transmission according to order setting and enabled as investment state.
Step S5, administrative unit output transmission test to each output, and there are two types of a states outputed, divides or closes
(i.e. 0 or 1) sends if outputing state is quartile and closes order to device, if outputed as coincidence, sends point order to dress
It sets, after device receives order, is decided whether to execute corresponding operation according to maintenance pressing plate state and enabled state, if maintenance
Pressing plate is investment state and outputs transmission and enable to be investment state, then executes operation, otherwise refusal operation.
Step S6, after the completion of outputing transmission test, administrative unit transmission at this time exits the enabled order of transmission to device, if
Administrative unit (is such as set as 10 minutes) within the set time not to any operation of transmission progress is outputed, then device itself will be certainly
Dynamic exit outputs transmission enabled state, and device reverts to the state outputed into the state outputed before being driven.
In the ICD model file of site protective device, as shown in Figure 1, in the logical device that inst value is " MGR "
Under, establish the data set that name value is " dsMgrForceDO ".In this data set, each FCDA (functional restraint data category
Property) quote to be actually needed and output outputing for transmission, it each outputs and uses CDC (public data class) type for SPC in ICD model
DO creation.The transmission of outputing that doName is " OutQtPro " is established in icd model simultaneously and enables DO, outputs the enabled DO of transmission
It is also contained in " dsMgrForceDO " data set.
After site protective device powers on, transmission DO is outputed accordingly according to model foundation.Administrative unit is established with device
After 61850 communications, " dsMgrForceDO " data set is parsed, is sent to device and reads service command, the enabled DO of transmission is outputed in reading
State send investment if it is to exit state that it is enabled, which to output transmission, to device and output the enabled order of transmission, device receives life
It is enabled to output transmission for investment after order.Meanwhile administrative unit passes through the state for reading service acquisition turnaround of unit pressing plate, if maintenance is
State is exited, investment maintenance pressing plate order is sent to device, if maintenance pressing plate has been put into, does not have to send.
Then, administrative unit obtains " dsMgrForceDO " data set of site protective device by 61850 services of reading
In it is all output real values (state outputed only there are two types of, point or close (i.e. 0 or 1)), at this point, in administrative unit
Obtained it is all to be carried out outputing outputing a little for transmission, finally, a little carrying out transmission test, site to outputing by remote control command
Protective device obtains the remote control command of administrative unit, according to order just corresponding transmission test, that is, puts into or exits and output biography
It is dynamic.
Administrative unit complete site protection equipment output transmission after, exit and output to the transmission of site protective device
The enabled order of transmission, after protective device receives order, exits enabled state, while device will be in " dsMgrForceDO " data set
All DO that output restore to the state entered before outputing transmission.If administrative unit did not output any one in 10 minutes
Point carries out outputing transmission test, then site protective device automatically exits from and outputs transmission enabled state, simultaneously
All outputing restores to entrance to output the state before transmission in " dsMgrForceDO " data set.Maintenance pressing plate does not move back automatically
Out, it is decided in its sole discretion, can exited or not exited by administrative unit.
The present invention provides a kind of site protective device based on 61850 and outputs drive method, will output transmission on the spot
Change and defined in the ICD model of protective device, site protective device and administrative unit are opened by analytic modell analytical model acquisition
What is be driven out outputs DO, and administrative unit obtains the state outputed by MMS and realizes opening for site protective device by remote control
Transmission test out.Through the invention, the difficulty that site protective device does not have liquid crystal that can not carry out outputing transmission test is solved,
It improves work efficiency.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications, these improvements and modifications can also be made
Also it should be regarded as protection scope of the present invention.
