Problems solved by technology

The collected data distribution technology is located in the application layer, there is a large amount of redundant data transmission, and the utilization rate of network resources is not high
Moreover, the existing intelligent substation information communication architecture is based on the traditional TCP / IP architecture, which has certain defects in flexibility, fault tolerance, and high efficiency. The competition between the internal protocols of the network makes the IP layer seriously hinder the network Increased performance hinders the development of new applications such as grid mobile access points, distributed information processing, and streaming media

Embodiment 1

[0040]Embodiment 1 of the present invention: an intelligent substation communication method based on an information center network, such as figure 1 shown, including the following steps:

[0041] S1. Client A sends a data access packet to upstream router A. The header of the data access packet includes a data access request and a unique routing identifier, and the unique routing identifier is an information name containing an authorization attribute.

[0042] Wherein, the authorization attribute includes authorization, entrusted authorization, and unauthorized; for data with a high security level, the authorization attribute of its unique routing identifier is authorized; for data with a general security level and reaching a threshold, the authorization attribute of its unique routing identifier is Delegated authorization; for data with a low security level, the authorization attribute of its unique routing ID is unauthorized.

[0043] The security level of the data is define...

Embodiment 2

[0047] Embodiment 2 of the present invention: a smart substation communication method based on an information center network, such as figure 2 shown, including the following steps:

[0048] S1, the client B sends the access message of the result data described in Embodiment 1 to its upstream router B;

[0049] S2, detecting whether the upstream router B has forwarded the result data, and if so, detecting whether the upstream router B has stored the result data, and if so, directly forwarding the result data to the client B by the upstream router B, If not, then detect whether other routers on the forwarding path store the result data according to the distance from near to far, obtain the result data from the nearest router, and forward it to client B; if not forwarded, just Turn to step S3;

[0050] S3. Detect whether the upstream router of the upstream router B has forwarded the result data, and repeat step S2 until a router storing the result data is found.

Embodiment 3

[0051] Embodiment 3 of the present invention: a smart substation communication method based on an information center network, such as image 3 shown, including the following steps:

[0052] S1. Client A sends a data access message to upstream router A. The header of the data access message includes a data access request and a unique routing identifier. The unique routing identifier is information including authorization attributes and forwarding attributes. name.

[0053] Wherein, the authorization attribute also includes authorization, entrusted authorization, and unauthorized; for data with a high security level, the authorization attribute of its unique routing identifier is authorized; for data with a general security level and reaching a threshold, the authorization attribute of its unique routing identifier It is delegated authorization; for data with a low security level, the authorization attribute of its unique routing ID is unauthorized.

[0054] The security level...

Abstract

The invention discloses an intelligent substation communication method and system based on an information center network. The method includes the steps that firstly, a client side A sends a data access message to an uplink router A, a message header comprises a data access request and a unique route distinguisher, and the unique route distinguisher is the information name comprising authorization attributes; secondly, the uplink router A forwards the data access message to a transformer substation data source end, the data source end returns a result message to a router in a transformer substation data transmission network, and a message header of the result message includes the responsive data access request, result data and the unique route distinguisher, wherein the result data and the unique route distinguisher are provided for the client side A; thirdly, the authorization attributes of the unique route distinguisher are detected, if the authorization attributes are authorization or delegation authorization, the router has the cache function, and the router is then used for storing the result data and forwards the result data to the client side A. According to the intelligent substation communication method and system based on the information center network, redundant data can be reduced, and the network resource utilization rate and the power data transmission efficiency are improved.

Description

technical field [0001] The invention relates to an information center network-based intelligent substation communication method and system, belonging to the field of intelligent substation network communication. Background technique [0002] The construction of the smart grid includes six links of power system generation, transmission, transformation, distribution, use and dispatch, and each link will generate massive data.
