Description
Technical field
The present invention relates to Automation of Electric Systems control technology and network communication technologies, are specifically related to a kind of intelligent power transformation
It stands interchanger IED facility information learning method.
Background technique
Intelligent substation is divided on the basis of IEC61850 communication protocol by intelligent primary equipment, networking secondary device
Layer building can be realized the modern substations of information sharing and interoperability between smart machine.Compared with conventional substation, intelligence
Changing the equipment and network interface of substation's wall and station level, only interface and traffic model are changed, but process layer by
Cable connection between traditional electric current, voltage transformer, primary equipment and primary equipment and secondary device, changes into electronics
The contents such as formula mutual inductor, intelligent primary equipment, combining unit, optical fiber connection.
Switch network equipment becomes the key foundation equipment of intelligent substation under such configuration, realizes equipment room
Interconnection, intercommunication, interoperability.Implement in engineering debugging and during operation and maintenance, the network of interchanger and by interchanger into
The system group network of the equipment of row interconnection, can be by link layer protocol network topology structure showing, but end of network equipment connection
End equipment can not perceive, and also can not just be visualized on network-management tool.
In the debugging of actual intelligent substation engineering and operation and maintenance, it often will appear following situation, secondary device is wrong
In misconnection to other exchange interfaces or other interchangers；Physical link failure；Logic void circuit abnormal failure.These situations
The efficiency of debugging is seriously affected, to increase the construction debugging cycle of Intelligent transformer station significantly；More some situations are being debugged
Shi Buyi exposure, may cause safety accident when operating normally, there is biggish security risk.
Summary of the invention
It is an object of the invention to propose a kind of intelligent substation switch IED facility information learning method, intelligent power transformation
Stand interchanger can the IED facility information that is connected of real-time learning interface, eliminate security risk, ensure power system security fortune
Row.
A kind of intelligent substation switch IED facility information learning method of the invention, specifically includes the following steps:
It configures interchanger and enables IED learning equipment function；Intelligent substation switch IED learning equipment function, it is similar to hand over
The mac learning functionality changed planes, the IED device name of intelligent substation switch learning records switch port connection；
The goose/sv message that interchanger issues access IED equipment captures；
Interchanger parses the goose/sv message of capture, extract the source mac of message, purpose mac, IED name,
appid；The IED information (control block for multicast purpose mac, the IED publication that source mac, IED name, IED are issued extracted
Appid information) and message receiver message breath record be saved in data structure, pass to IED learning management module (be intelligence
The software function module of substation's interchanger IED learning equipment result data processing), the IED learning management module is to study
The IED facility information arrived carries out aging, refreshing, addition and deletion；
Interchanger ceases the IED information extracted plus message receiver message, is saved by hash table mode,
Record IED learning equipment result；
Interchanger is added operation, delete operation according to entry to the IED learning equipment result, updates operation, old
Change operation and inquiry operation.
Above-mentioned interchanger enables IED learning equipment function and is configurable, can be enabled based on port or global configuration, specifically
Steps are as follows:
Global configuration enables IED learning equipment function on the interchanger of all connection IED terminals；
Needs are realized according to engineering system, are revised as enabling IED learning equipment function by port.
The goose/sv message that above-mentioned interchanger issues access IED equipment captures, the specific steps are as follows:
Into the goose/sv message of interchanger, forwarding table is searched according to purpose mac, if failure is searched, on message
Give the cpu of interchanger；
Into the goose/sv message of interchanger, forwarding table is searched according to source mac, if failure is searched, message up sending
To the cpu of interchanger；
Into the goose/sv message of interchanger, interchanger is matched according to the acl rule issued, if meeting matching
Rule, message up sending to the cpu of interchanger.
It is that key carries out information storage with the purpose mac or appid；It is that key progress information is deposited with the IED name
Storage；The information of storage further includes message receiver message breath.
Operation is added according to entry to the IED learning equipment result, delete operation, updates operation, burnin operation
And inquiry operation, the specific steps are as follows:
IED information for learning searches IED learning table using purpose mac as keyword；
If there is no the entry, then it is added；If there is the entry, contents in table is compared, if content is consistent
It does not handle then, it is inconsistent, it is updated；
List item management module (implementor name that intelligent substation switch IED learning equipment arrives table corresponding with port, equipment hair
The management interface module of the softwares list items such as information purpose mac, appid of cloth table corresponding with port) it receives and is specified using deletion
List item instruction deletes specified IED and learns list item entry；It receives and deletes all IED study list item instructions, then delete all list item items
Mesh；
After the entry learnt is added successfully, start to add timer, timing is the ageing time of configuration；Aging is fixed
When device reach before IED have corresponding message forwarding transmit, then update ageing timer；Timer no corresponding IED after reaching
Message forwarding transmission, then carry out aging deletion.
If there is no the entry, then it is added；Construction is carried out with IED name for the IED appid table of key simultaneously
Addition, construction are added with port for the IED table of key.
If there is the entry, compare contents in table, if content unanimously if do not handle, it is inconsistent, be updated；Together
Shi Gengxin IED appid table updates IED table.
Above-mentioned list item management module is received using specified list item instruction is deleted, and is deleted specified IED and is learnt list item entry, together
Shi Gengxin IED appid table updates IED table；It receives and deletes all IED study list item instructions, then delete all list item entries, together
When delete IED appid table and IED table.
Compared with existing technical situation, present invention effect achieved is:
The present invention realizes that intelligent substation switch can learn connected IED facility information, in conjunction with intelligent substation
Network visualization system realizes Networked E-Journals improved efficiency, quick bond-allocating and wiring error problem；Ensure that wiring is correctly closed
Reason, eliminates safe hidden trouble, and ensures safe operation of power system.
