Description
Technical field
The present invention relates to a kind of network pressure automatic testing equipment, and in particular to a kind of intelligent substation relay protection network
Automatic pressure-testing device and method.
Background technology
In order to break away from the dependence to interchanger and clock system, at present, transformer station process layer takes mostly
" directly adopting straight jump " pattern, i.e. protection device optical fiber is connected directly to MU (combining unit), the SV (samplings that collection combining unit sends
Value), the sample-synchronous between different MU are realized by interpolation calculation；Meanwhile, protection device optical fiber is connected directly to intelligent terminal, to
Intelligent terminal sends GOOSE (transformer substation case of general object-oriented) trip signal, and gathers breaker by intelligent terminal
Position signalling.Connection locking information of the protection device across interval is then transmitted using GOOSE modes by process-level network, such as circuit
Protection starts bus protection failure, bus protection blocked line reclosing, the side of bus protection shunt tripping main transformer three etc..Additionally, intelligence
Substation relay protection device and station level network connection, MMS (manufacture message specification) alarm action letter is sent to monitoring backstage
Cease and receive the operational order of monitoring backstage.
In the case of GOOSE heartbeats naturally synchronization, SCD file configuration error, IED equipment faults, protection large area action,
Occur pressure flow on process layer and station level network, MU, intelligent terminal occur giving out a contract for a project in the case of hardware fault, " directly adopt straight
Pressure flow can be also produced on jump mouth ", especially in the case where network produces loop situations, network pressure flow can be automatically formed quickly,
Protection equipment on normal operation produces influence.At present, in converting station debugging relay protection device network performance test, lack
Weary effective means, protection type is varied, and corresponding complete technical specification support is lacked again, therefore, generally existing
Test leak, causes the network performance during field adjustable to protecting not test, or the situation such as method of testing is incorrect,
Potential safety hazard is left to the intelligent substation after input.
The content of the invention
It is an object of the invention to provide a kind of intelligent substation relay protection network pressure automatic testing equipment and method,
To solve the problems, such as to be proposed in above-mentioned background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of intelligent substation relay protection network pressure
