Example Embodiment

[0019] The present invention is described in further detail below in conjunction with the accompanying drawings and specific embodiments:

[0020] like figure 2 As shown, the real-time analysis method of the SV message of the smart substation of the present invention includes, adopting the optical splitting technology, and intercepting the SV message sent by the IED device according to a certain proportion without affecting the normal communication of the network; from the captured SV message In this paper, parameters such as Header MAC, Priority Tagged Ethertype, Header, and MAC calculation verification are obtained respectively, so as to parse the obtained information. SV packets are encoded in binary format, and parameters such as Header MAC, Priority Tagged Ethertype, Header, and MAC calculation checksum in each frame of packets have a fixed length and order. Read according to the order and the number of bytes to complete the capture of each parameter of the message. Th...

Abstract

The invention discloses a real-time analyzing method of an SV (Sampling Value) message of an intelligent substation. The real-time analyzing method comprises the following steps of: A, grabbing the SV message sent by an IED (Intelligent Electronic Device); B, respectively obtaining Header MAC, Priority Tagged Ethertype, Header and MAC (Multi-Access Computer) computation information from the grabbed SV message; and C, analyzing the obtained data information. The real-time analyzing method of the SV message of the intelligent substation has the beneficial effects that the SV message sent by all IEDs can be analyzed; and the SV message parameters are analyzed to realize real-time conversion of the SV message. The converted SV message format is consistent with a remote measuring expression format of the conventional substation; and the specific information of SV is correctly indicated, so that the debugging efficiency is improved. Especially, when the message is analyzed, the site construction is not affected, and the normal communication of the devices is ensured.

Description

technical field [0001] The invention relates to a network communication of an electric power system; in particular, it relates to a real-time analysis method of an intelligent substation SV message. Background technique [0002] In recent years, the rapid development of computer technology, information processing technology and network communication technology has had a huge impact on the substation automation system. The application of network communication in substation is increasing day by day. The IEC61850 standard introduces network communication between the process of primary equipment and secondary equipment, which leads to great changes in the substation automation system. The IEC61850 standard is an important standard formulated by the international IEC TC57 organization for the substation automation system. By standardizing the communication network and system of the substation automation system, the purpose is to realize the interoperability of intelligent device...
