Embodiment Construction

[0015] The present invention will be further described below using the accompanying drawings and specific embodiments.

[0016] Such as figure 1 As shown, the existing "four-in-one" ring networking method for smart substations refers to switches that connect one or more bay merging units, intelligent terminals, protection devices, and measurement and control devices, such as figure 1 Middle switch 1 and switch 2 are cascaded with each other, and the switches at both ends are connected to the switch connected to the station control layer equipment, such as figure 1 The middle switches 3 are cascaded respectively to form a ring network topology structure, and the four kinds of messages GOOSE, SV, MMS, and IEEE 1588 are all transmitted in the ring network.

[0017] Such as figure 2 As shown, the intelligent substation "four networks in one" of the present invention is based on the method of ring networking, which improves the topology of the existing ring network. In the case ...

Abstract

The invention discloses a method for transmitting four kinds of messages of an intelligent substation in one physical network based on annular networking. The method comprises the steps of cascading switches which are respectively connected with at least one interval combination unit, intelligent terminal, protection device and measurement and control device; and cascading the switches at two ends with one switch which is connected with station control layer devices, thereby forming an annular networking topological structure, wherein four kinds of messages: GOOSE, SV, MMS and IEEE1588 can be transmitted in an annular network, interval layer devices are connected with one switch to independently form a small network, and the network traffic on a main path of the annular network is reduced by increasing branch paths, thereby mitigating the load pressure of the switches. The method is applicable to an occasion for optimizing the network traffic under the condition that the existing network bandwidth is fixed.

Description

technical field [0001] The invention relates to the field of network communication of intelligent substations, and relates to a ring-type networking method based on "four networks in one" of intelligent substations. Background technique [0002] With the advancement of research on vertical bay integration technology, integrated protection technology, and integrated monitoring system technology, the research on information sharing of smart substations has also attracted great attention. The information sharing of the whole station no longer has the isolation of the station control layer network and the process layer network. In theory, information access from any device in a shared network to other devices can be realized, which greatly improves the flexibility and efficiency of communication services. , Standardization, in line with the target requirements of smart substations, it is bound to be the development trend of the secondary equipment networking of smart substations...
