Specific embodiment
With reference to the accompanying drawing and specific embodiment the present invention is described in detail.
The intelligent O&M method towards GOOSE/SV soft pressing plate that the present invention provides a kind of, comprising the following steps:
Step 1: establishing empty circuit chain circuit alarming rule according to the channel GOOSE APPID serial number；By GOOSE output model,
It opens the associate field in model in second data and is set as soft pressing plate short address associate field, establish soft pressing plate and GOOSE
It outputs model, open model and soft pressing plate is formed by incidence relation between empty circuit, utilize the empty circuit chain circuit alarming
Rule is to realize that Quadratic Imaginary circuit uplink alerts the auto-associating with soft pressing plate.
Cell device chain void circuit link state is judged and is alerted by message recipient, and observing and controlling/protective device is come
Say, have in model the alarm of multiple groups GOOSE/SV link on-off with quality alarm as shown in Figure 1, every group of alarm by mapping ruler with
Empty circuit is associated, so as to judge the link state in every empty circuit.
Wherein, the building process of the mapping ruler of empty circuit chain circuit alarming includes: that chain rupture alarm short address chain rupture field is
LNKxxyyzzzz, xx are not used, and being defaulted as 00, yy is that chain rupture accesses vertex type, and zzzz is the chain rupture alarm signal in this access
According to the serial number of APPID layout from small to large under point, since 0, as shown in Figure 2.Different types of chain rupture alarm signal is closed
The empty circuit of connection is sorted after also distinguishing by type, and every chain rupture alarm is associated according to putting in order with corresponding empty circuit
No. CPU is also distinguished simultaneously, operation object will be in same CPU.
Process layer device link state is similar to cell device, and difference is the chain circuit alarming of process layer device by being spaced
Layer measure and control device forwarding, can be found in measure and control device by link information in SCD and open access point, opened access point according to observing and controlling and find
The remote signalling point of monitoring is sent, the associate field RLTxxyyzzzz of two data point short addresses is identical.For associate field
RLTxxyyzzzz, wherein RLT is associate field keyword, and xx is CPU number, and yy is tables of data ID, and zzzz is associated data note
Record ID.It is then associated data when field is identical, if there is multiple data in the same short address, associated data mark is identical.
Note: data are 4 byte integers of 16 systems mark, and onrelevant data are identified as " RLT00000000 ", when there are two types
When the incidence relation of type, second of incidence relation is in second data separated with ", ".
GOOSE transmission pattern exports soft pressing plate foundation with GOOSE by short address and is associated with, and soft pressing plate and GOOSE output it
Between be one-to-many relationship, as shown in Figure 3.When reception two point GOOSE, which is opened, has control soft pressing plate into model, GOOSE is opened into mould
Associate field in type in second data is set to off the data record of joint control soft pressing plate；When GOOSE is opened into model without control
When soft pressing plate processed, the associate field in second data of two point is set as in vain, being indicated with RLT00000000, as shown in Figure 4.
GOOSE outputs model, opens and is associated with criterion between model and soft pressing plate are as follows: GOOSE outputs model and soft pressing plate
Short address associate field is identical (except RLT00000000)；GOOSE opens associate field and soft pressure in second data of model
Plate short address associate field is identical (except RLT00000000)；Model belongs to one No. CPU；Soft pressing plate short address data type:
RYB；Soft pressing plate shielding: RLT00000000.
In the above-mentioned first step, model is outputed by establishing soft pressing plate and GOOSE, opens the incidence relation shape between model
At each empty circuit, being associated between soft pressing plate and empty circuit is realized, is then built using by the channel GOOSE APPID serial number
Vertical empty circuit chain circuit alarming rule, realizes the mapping association of soft pressing plate and empty circuit chain circuit alarming.
Step 2: establishing intelligent substation secondary using intelligent substation integrated monitoring system analysis SCD model file
Empty loop data model.
According to the element in empty circuit, three data models need to be established.First: GSE model, is mainly indexed by device
Number, signal type (0-GOOSE, 1-SV), control block path (GOOSE, SV control block), the fields such as APPID constitute；Second:
Empty loop model, mainly not by GSE call number, output IED, input IED, A net state remote signalling ID, B net state remote signalling ID, message
The fields such as matching alarm are constituted；Third: line model, mainly by outputing IED call number, opening into DO, opening into DO real signal, open
Enter IED call number, outputs real-time number of DO, outputs the fields compositions such as DO, type, empty circuit call number, control block path.
Third step, establishes the intelligent alarm on-line testing model library of Quadratic Imaginary circuit soft pressing plate state, and real-time monitoring is secondary
Soft pressing plate state on empty circuit, and judge that the soft pressing plate state monitored is corresponding in intelligent alarm on-line testing model library
Soft pressing plate state it is whether variant, if variant, start alarm, operation maintenance personnel reminded to carry out the maintenance of pressing plate state.
In addition, establishing Knowledge Verification Model according to the preset state of pressing plate and current state, it is then introduced into intelligent alarm rule
Library starts intelligent alarm when monitoring the pressing plate abnormal state on secondary circuit, and O&M is reminded to carry out the inspection of pressing plate state
It repairs, detailed process is as shown in Figure 5.
Wherein, intelligent alarm rule base refers to, the warning information of magnanimity is classified and is classified, then to classification and point
The warning information of grade and establish the database of Different Rule.Such as warning information is divided into: accident, exception, displacement, out-of-limit, informing
Five classes.According to severity of consequence and pressing degree produced by not responded to warning information, and can be divided into high, medium and low
Three priority.Rule, which has, is divided into out-of-limit dead zone rule, and redundant alarm inhibits rule, and abnormality alarming rule repeats to alert automatic
Eliminate rule etc..Increase pressing plate status check model in intelligent alarm rule base, O&M people is reminded according to the abnormal frequency of equipment
Member is checked and is overhauled in time to equipment.
4th step, according to the alarm of Quadratic Imaginary circuit uplink and the related information of soft pressing plate and the Quadratic Imaginary circuit of foundation
Data model realizes the visualization of intelligent substation secondary void circuit top board state.
Specifically, the chain circuit alarming signal and associated platen state-driven using each IED equipment visualize circuit on-off
The empty circuit of dynamic is carried out to show.It is shown centered on specific IED equipment, all void circuits are by this IED according to input, output sequence
Arrangement.Other correlation IED equipment, which are only shown, has the empty circuit of line with this IED equipment；The empty corresponding input of circuit setting in part
With output pressing plate, when pressing plate exits, this empty circuit is off-state；When some IED maintenance pressing plate investment, needing will be related
GOOSE link indicated using yellow, maintenance pressing plate state can be obtained according to the maintenance mark in MMS message；The IED at this interface
All alarm status information can click observation；All inputs can be with real-time display magnitude comprising switching value and analog quantity.
It is as shown in Figure 6 that empty circuit secondary device soft pressing plate visualizes interface.
