Abstract

The invention relates to a power distribution terminal 104 message parsing system and a parsing method of the power distribution terminal 104 message parsing system. The parsing system implemented based on an IEC 61850 standard comprises a power distribution terminal, a communication module and a parsing module. The power distribution terminal obtains IEC61850 model configuration data of a power distribution terminal measuring point and measured data of a power distribution network and transmits the configuration data and the measured data to the communication module; the communication module transmits the data of the power distribution terminal to the parsing module; the parsing module parses the data transmitted by the power distribution terminal according to the 104 protocol and acquires the configuration data of the power distribution terminal measuring point and remote communication and telemetry data of the measuring point to generate remote communication and telemetry data sheet messages of the measuring point. According to the technical scheme, improvement on power distribution network information integration quality is promoted, so the automated operation level of the power distribution network is improved, and loss caused by a power failure is reduced. Accordingly, the power distribution terminal 104 message parsing system and the parsing method have great social value and economic value for guaranteeing safe operation of the power distribution network.

Description

Technical field: [0001] The present invention relates to the field of electric power system and automation thereof, and more specifically relates to a message analysis system and analysis method of power distribution terminal 104 based on the IEC61850 standard. Background technique: [0002] The distribution automation system is a network system that uses modern communication and computer technology to remotely monitor and control the on-line equipment in the distribution network. At present, in my country's distribution network system, there are mainly 101 statutes, 104 statutes and DNP3.0 statutes for telecontrol protocols. The 101 and 104 statutes are stipulated by the basic telecontrol supporting standard formulated by the IEC Power System Control and Communication Technical Committee: "IEC 60870-5-101-2003 Remote Control Equipment and Systems". [0003] In the current distribution network automation system, the 104 protocol is a common communication protocol for the co...
