Embodiment
As illustrated in fig. 1 and 2, the present invention automatically analyzes including a kind of intelligent substation secondary protection equipment security isolation measure
Method, comprise the following steps：
A：Based on SCD models, the empty path incidence model between first and second equipment correlation model and secondary device is built：Utilize
The information modelings such as the primary equipment configuration of SCD file, secondary device configuration, communication, pressing plate, structure first and second equipment association mould
Empty path incidence model between type and secondary device；
B:Analysis obtains the equipment collection for needing to isolate：The primary equipment of a secondary device or deactivation to be isolated is obtained, such as
Fruit is the primary equipment for needing to disable, then obtains the secondary device of correlation automatically according to correlation model, once set what is disabled
It is standby that the secondary device collection with isolation is associated with to obtained related secondary devices all therewith；If one to be isolated two
Secondary device, then the equipment collection secondary device body with isolation isolated as needs；
C：The secondary device input maintenance pressing plate concentrated to the equipment that needs are isolated, and secondary device collection to be isolated is judged successively
Whether middle secondary device is protection equipment, then enters step D if not protection equipment, if protection equipment, then protection is moved back
Step D is entered back into after going out；
D：The secondary device and/or the method for operation of primary equipment concentrated to the equipment that needs are isolated check：If once
Equipment does not have a power failure, then ensures that primary equipment has double set protections and at least a set of protection normal operation, then carry out next
Walk, otherwise direct termination of security analysis process；
E：Secondary device in above-mentioned steps D is being had a power failure or the safety measure of not power-off condition is former according to secondary device successively
Then, the safety measure operation that the secondary device that analyzing can overhaul needs is reliably isolated, so as to be operated according to this safety measure
Complete security isolation.Isolated operation is carried out to the equipment at loop both ends and loop in the present invention（Isolated operation refers to exiting
The transmission in GOOSE and SV loops, receive pressing plate, it is also possible to which out of service, output clamping including protection equipment etc. operates）, such as
Fruit primary equipment does not have a power failure, then must assure that and protected with double sets and have a set of protection normal operation, otherwise isolated process is moved back
Go out.
The each secondary device progress security isolation concentrated in the step E to secondary device to be isolated specifically includes as follows
Step：
E1：All secondary circuits in each secondary device concentrated to secondary device to be isolated travel through successively, obtain void
The equipment that the loop other end is connected, so as to judge that the empty loop of each secondary circuit is to belong to GOOSE loops or SV loops；
Equipment and loop to loop both ends carry out isolated operation（Isolated operation be generally referred to as exit GOOSE and SV loops transmission,
Receive pressing plate, it is also possible to which out of service, output clamping including protection equipment etc. operates）, must if primary equipment does not have a power failure
It must ensure that there are double sets to protect and have a set of protection normal operation, otherwise isolated process exits；
E2：If the empty loop of secondary device to be isolated belongs to GOOSE loops, the GOOSE of the to be isolated equipment related to this
Loop and terminal device perform peace and arrange isolation：Specifically include and exit equipment GOOSE output clampings, exit the GOOSE loops other end
The GOOSE of operational outfit receives pressing plate, and wherein equipment concentrates the GOOSE between the secondary device to be isolated related to primary equipment
Pressing plate does not move back；
E3：If the empty loop of equipment to be isolated is to be not belonging to GS loops, equipment to be isolated is to belong to SV loops, related to this
Equipment to be isolated SV loops and the other end perform peace and arrange isolation：Specifically include：The protection equipment of the SV loops other end need to move back
Go out SV and receive pressing plate, it is necessary to disable the protection device for receiving SV, device SV receives pressing plate and can not moved back.
This patent is based on new SCD models, empty path incidence mould between the association of first and second equipment of structure and secondary device
Type.The primary equipment having a power failure for needs, associated secondary device is obtained according to correlation model automatically.For needing to overhaul
Secondary device, other secondary devices for being associated are searched by Quadratic Imaginary loop, had a power failure or not according to secondary device
The peace of power-off condition arranges principle, and the peace that analyzing can be such that the secondary device of maintenance reliably isolates arranges operation；
Peace arranges the main principle of isolation as follows：During the field operation such as the verification of 1 device or defect elimination, sampling, tripping operation should be isolated, closed
Lock, open it is related to operational outfit in failure loop contact, and ensure the normal operation of operational outfit；2nd, the verification of single complete equipment or
During person's defect elimination, it should stop to use as a servant primary equipment；, can not when the verification of the secondary device of duplicate system retrofit, only single complete equipment or defect elimination
Stop using as a servant primary equipment, but prevent primary equipment unprotect from running；3rd, there is the optical cable of soft pressing plate for sending side or receiving side, to the greatest extent
Amount does not turn off optical fiber, ensures that soft pressing plate has disconnected before disconnecting；4th, during the security isolation of loop, dual safety quarantine measures are taken.It is first
The transmission pressing plate of apparatus for examination and repair before this, followed by the reception pressing plate of related running gear, it is also contemplated that the maintenance pressure of apparatus for examination and repair
Plate.According to isolation principle, using following steps：
A, the secondary circuit of equipment is traveled through, the equipment for obtaining empty loop information and the connection of the loop other end；
B, the method for operation of xegregating unit is checked, if primary equipment does not have a power failure, must assure that and protected with double sets
And there is a set of protection normal operation, otherwise isolated process exits.
C, peace is performed to GOOSE loops and terminal device and arranges isolation：Exit equipment GOOSE output clampings；GOOSE is exited to return
The GOOSE of road other end operational outfit receives pressing plate；When disabling primary equipment, the GOOSE between the secondary device that equipment is concentrated
Pressing plate can not move back；
D, the SV loops to equipment and another both ends perform peace and arrange isolation：The protection equipment of the SV loops other end need to exit SV receptions
Pressing plate；, it is necessary to disable the protection device for receiving SV when not disabling primary equipment, device SV receives pressing plate and can not moved back.
The present invention is based on SCD models, empty path incidence model between the association of first and second equipment of structure and secondary device.It is right
In the primary equipment that needs have a power failure, associated secondary device is obtained automatically according to correlation model.Two overhauled for needs
Secondary device, the other secondary devices being associated are searched by Quadratic Imaginary loop, having a power failure or do not having a power failure according to secondary device
The peace of situation arranges principle, and the peace that analyzing can be such that the secondary device of maintenance reliably isolates arranges operation, further efficient to examine peace
Arrange operation order whether safe and reliable.
