Problems solved by technology

[0002] At present, there are two three-layer protocols based on 61850-based SV and GOOSE in the process layer network of smart substations. At this stage, standard two-layer Ethernet switches are used for networking. The flow control of network data flow is realized by VLAN technology. Using this The technology needs to introduce additional VLAN configuration information that has nothing to do with power services. This information is not easy to incorporate into the model system of 61850, which increases the difficulty of management. VLAN technology is still unable to accurately restrict illegal data flows.

Abstract

The invention relates to an intelligent substation process layer network data flow control method, which comprises the following steps of: establishing a data flow control template file based on an IEC61850 communication protocol, wherein the data flow control template file comprises a device attribute, a port attribute, a real intelligent electronic device IED list attribute, a virtual intelligent electronic device IED list attribute and a data flow control list attribute of a data flow control device; generating an engineering instance file; and importing the engineering instance file into the data flow control device, reading a data flow control list to establish a network flow control logic of the data flow control device, and realizing control of the data flow. According to the invention, three-layer data flow control of a sampling value SV protocol and a general object-oriented substation event GOOSE protocol can be realized only by configuring a power protocol identifier APPID,unified modeling and unified management of power communication services are realized, the management difficulty is reduced, the technical requirements of configuration personnel are reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for controlling data flow in a process layer network of an intelligent substation. Background technique [0002] At present, there are two three-layer protocols based on 61850-based SV and GOOSE in the process layer network of smart substations. At this stage, standard two-layer Ethernet switches are used for networking. The flow control of network data flow is realized by VLAN technology. Using this The technology needs to introduce additional VLAN configuration information that has nothing to do with power services. This information is not easy to incorporate into the model system of 61850, which increases the difficulty of management. VLAN technology is still unable to accurately restrict illegal data flows. At this time, it is necessary to bind data through switch ports The source MAC address of the flow can only be done, which also requires additional ...
