Embodiment Construction

[0056] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0057] Most of the telecontrol transmission protocols currently operated by power dispatching are based on the IEC104 protocol transmitted over the TCP / IP network. The IEC104 protocol includes three types of formats, namely, numbered information transmission (I format), numbered monitoring function (S format) and Unnumbered control functions (U format). In order not to affect the normal business transmission, the present invention adopts the mirror interception method to obtain the transmission message, and through a set of multi-dimensional characteristic indicators, conducts online abnormal detection for the automatic telecontrol transmission of electric power dispatching, and then realizes the real-time monitoring of electric power telecontrol Monitoring, fault warning.

Abstract

An online power telecontrol IEC104 transmission abnormality detection method relates to a power dispatching telecontrol network transmission abnormality detection method. At present, there is no effective online monitoring, analysis and diagnosis method for the running IEC104 telecontrol communication. The invention comprises the following steps: 1) message interception and capture; 2) message splicing; 3) IEC104 message parsing; 4) plant and station combined statistics; Transmission abnormality discrimination and control transmission abnormality discrimination. This technical solution reduces the work intensity and improves the automatic operation and maintenance level of power dispatching; it can actively discover abnormal conditions in the process of control information transmission, and ensure the normal operation of the power dispatching control system; it can detect transmission faults intuitively and clearly, and can detect invisible faults Carry out early warning; judge the network failure or the communication failure of the factory station.

Description

technical field [0001] The invention relates to a method for detecting abnormal transmission of electric power dispatching telecontrol network, in particular to an online electric telecontrol IEC104 transmission abnormal detection method. Background technique [0002] With the development of power grid dispatching technology and the improvement and reliability of automation equipment, the operation mode of "unattended and few people on duty" in substations is promoted. As the core support for the safe operation of the power grid, the dispatching automation system is becoming more and more critical, and the automation system is increasingly becoming a guarantee for the power grid. The key link of safe, high-quality, reliable and stable operation. The safe and reliable transmission of power telecontrol information is the basic prerequisite for the normal operation of the power automation system. In actual production work, the abnormality and fault discrimination of the automat...
