The configuration file of the system to be protected includes whole station intelligent electronic device (intelligent electronic device, IED
(Intelligent Electronic Device)) name, messaging parameter, data set, all kinds of controlling values and device virtual terminator
Connection type.Virtual terminator connection type is equivalent to the cabled manner in traditional power station.Wherein, the virtual terminator connection type pair
It is completely sightless in operation maintenance personnel, so the parsing to the configuration file is needed to match to obtain full transformer substation system
Set the connection type of the virtual terminator in file.Further, it by analysis result can also include at the control device display
It is formed for the visible equipment correspondence figure of operation maintenance personnel, that is, first numerical relation in interface.This implementation
In example, first numerical relation can be the numerical relations such as matrix, vector.

A certain IEDi needs the branch being disconnected, if the j of i row vectors is classified as 1, the j column vectors of the corresponding IEDi of that i row correspond to branch
Bj is identical as the direction of IEDi, and the corresponding output branch needs of IEDi are disconnected.If the j of i row vectors is classified as -1, that i row pair
The j column vectors of the IEDi answered correspond to branch Bj with the direction of IEDi on the contrary, IEDi corresponding input branch needs are disconnected.It is described
Second numerical relation can be expressed as：
Wherein, qijIndicate that branch j is related with i-th of cut set and direction is identical, q for 1ijBranch j and i-th are indicated for -1
Cut set is related and direction is on the contrary, qijIndicating branch j for 0, related and direction is uncorrelated on the contrary to i-th of cut set.
Step S302, when any appliance monitored in the system to be protected needs to overhaul, according to second number
Relationship obtains maintenance matrix.
If to be overhauled to the parts formed multiple IED, that will this completely isolated multiple IED, and cannot break
Open the interconnected relationship of the inside between this multiple IED.According to the pass between the cut set indicated in second numerical relation
System, it is only necessary to the corresponding fundamental cutsets of IED for overhauling part will be needed to carry out linear, additive, can obtain what we needed to close
Communicate branch.
Step S303 needs the corresponding each communication leg of the repair apparatus overhauled to close according to the maintenance matrix majorization
It closes.
In the present embodiment, as shown in figure 4, the step S303 includes：Step S3031 to step S3033.
Step S3031 is built according to each soft pressing plate in the system to be protected and the relationship between each communication leg

Control word is realized.
For IED, each soft pressing plate correspond to IED equipment partial function and first numerical relation or
A plurality of branch association in second numerical relation.For example, once the GOOSE pressing plates of IED equipment exit, what which received
The GOOSE message of other equipment is all considered as invalid data, then all branches for receiving the device signal are considered as disconnection.In order to
The associated branch for accurately disconnecting IED equipment, equally describes the relationship of branch and soft pressing plate using matrix, that is, described the
Three numerical relations.Relational matrix Yn×rIt can be expressed as：
Wherein, yijIndicate that branch i is corresponding with soft pressing plate j for 1, yijIndicate that branch i is uncorrelated to soft pressing plate j for 0.
Wherein, soft pressing plate be not turned off a little, and with the communication branch in the first numerical relation and second numerical relation
Road is not to correspond, so in order to further ensure that security isolation target device will use first numerical relation to correspond to
Cut set matrix coordinate the relational matrix of branch and soft pressing plate that the third numerical relation indicates to use.
In the present embodiment, as shown in figure 5, after step S303, the method further includes：
Step S304, the carry out message checking processing between the relevant device of the repair apparatus.
