Description
Technical field
The present invention relates to a kind of intelligent transformer substation communication method and system based on information centre's network, belong to intelligent power transformation
Stand network communication field.
Background technology
The construction of intelligent grid comprising the sending out of power system, it is defeated, become, match somebody with somebody, with and six links of scheduling, each link can produce
Raw mass data.Power communication and transmission network covering every field, are presented the development trend of ubiquitous interconnection, ubiquitous data
Network carrying production management, weather information, office information system and scientific research etc. are applied.With technology of Internet of things and cloud computing technology
In the extensive use of power industry, future electrical energy data network will cover plant stands at different levels, control centre, power supply unit, electric power business
The Room, electric charging station, electric intelligent cell etc..
In transformer substation system, to meet to equipment condition monitoring, fault detection and location, harmonic detecting and the quality of power supply
The demand such as administer, transformer station is mounted with that a large amount of species are various, standard differs, poor compatibility and a series of costly of maintenance upgrade
Equipment.These equipment have real time data amount less, requirement of real-time is not high, rely on magnanimity historical information, analysis amount of calculation is huge
Big the characteristics of.With carrying forward vigorously for intelligent substation and gradually forming for electric power big data environment, intelligent substation systems at different levels
The data of system are exponentially increased sharply, it is necessary to which the data to transformer station PB grades carry out unified monitoring, analysis and fault diagnosis processing.Adopt
The data dissemination techniques of collection are all located at application layer, there is mass of redundancy data transmission, and network resource utilization is not high.Also, it is existing
Some intelligent transformer substation information communication constructions are based on conventional TCP/IP architecture, in the side such as flexibility, fault-tolerance, high efficiency
The competitive relation that face is present between certain defect, network internal agreement causes the IP layers of serious lifting for hindering network performance,
Hinder the development of the new opplications such as power network mobile access point, distributed information processing and Streaming Media.
The content of the invention
It is an object of the present invention to provide a kind of intelligent transformer substation communication method and system based on information centre's network,
Redundant data can be reduced, network resource utilization and electric power data efficiency of transmission is improved.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：
A kind of intelligent transformer substation communication method based on information centre's network, comprises the following steps：
S1, upstream router A sends data access message to customer end A, and the heading of the data access message includes
Data access request and unique Route Distinguisher, unique Route Distinguisher are the information name comprising authorization attribute；
S2, upstream router A forward data access message to substation data source, and data source returning result message is arrived
Router in substation data transmission network, the header of the result message includes the data access request of response, is supplied to
The result data of customer end A and unique Route Distinguisher；
S3, detects the authorization attribute of unique Route Distinguisher, if authorization attribute is mandate or delegable, and router
With caching function, then router is stored to result data, and forwards result data to customer end A；
S4, the access message of customer end B upstream result data described in router B forwarding steps S3；
S5, detects the whether forwarded over result datas of upstream router B, if forwarded over, just detection upstream router B
Whether the result data, if so, then directly the result data is forwarded to customer end B by upstream router B, if not having if being stored with
Have, then detect whether other routers are stored with the result data on forward-path according to distance, from closest
The result data is obtained in router, and is transmitted to customer end B；If without forwarded over, going to step S6；
S6, the detection upstream router B whether forwarded over result data of upstream router, repeat step S5, until
Untill the router for finding the result data that is stored with.
In the foregoing intelligent transformer substation communication method based on information centre's network, the authorization attribute also includes not awarding
Power；The high data of level of security, the authorization attribute of its unique Route Distinguisher is mandate；Level of security is general and reaches threshold value
Data, the authorization attribute of its unique Route Distinguisher is delegable；The low data of level of security, its unique Route Distinguisher
Authorization attribute is unauthorized.
In the foregoing intelligent transformer substation communication method based on information centre's network, according to ieee standard " IEEE
