Transformer substation message analysis device

Abstract

The invention discloses a transformer substation message analysis device which comprises a message acquisition module, a control module, a man-machine interaction module, a display screen and a powersupply module, wherein the message acquisition module acquires a substation communication message and transmits the substation communication message to the control module; the man-machine interactionmodule is provided with a key for selecting a communication protocol; the man-machine interaction module selects a communication protocol and then transmits the communication protocol to the control module; the control module extracts, analyzes and translates the collected communication messages according to the selected communication protocols and feeds the translated messages back to the displayscreen to be displayed; the power module is electrically connected with the control module, the man-machine interaction module and the display screen. According to the analysis device, the transformer substation communication message is collected through the collection port; the message is extracted, analyzed, translated and displayed according to the adopted communication protocol, so that workers are assisted in understanding message semantics and quickly positioning defect generation reasons, multiple protocols can be supported, and the analysis device is convenient and quick to use.

Description

technical field [0001] The invention relates to the technical field of substation monitoring, in particular to a substation message analysis device. Background technique [0002] The substation automation monitoring system is one of the important systems in the substation, which plays an important role in the measurement, monitoring and control of the power equipment in the substation. The communication protocol is an important guarantee for realizing reliable, fast and accurate communication between relay protection devices, automation equipment and monitoring systems in substations. Communication protocols commonly used in substations include IEC60870-5-103 communication protocol (103 protocol) and IEC61850 communication protocol (61850 protocol). Problems such as communication interruption, abnormal data transmission, and data status mismatch are the most common defects in substation communication. These defects usually require staff to be familiar with packet capture to...

Problems solved by technology

Commonly used communication protocols in substations include IEC60870-5-103 communication protocol (103 protocol) and IEC61850 communication protocol (61850 protocol). Problems such as communication interruption, abnormal data transmission, and incompatible data status are the most common defects in substation communication. These defects usually require staff to be familiar with packet capture tools and the ability to analyze communication protocol messages, but substation workers are usually not familiar with these. In addition, the packet capture tools and operation steps required by different manufacturers' equipment are also different. Even more, it increases the cost of learning. Therefore, in the process of dealing with defects, it is usually necessary to remotely seek help from equipment manufacturers for defect handling, which greatly reduces the efficiency of defect handling and seriously affects the safe and stable operation of substations.

For example, the Chinese patent with the publication number CN106549958A and the publication date of 2017.3.29 - a real-time message analysis and verification system and method, the patent realizes the analysis of the message by capturing packets, translating and verifying the message , but it is not visualized, and it also checks a single communication protocol, which is inefficient, and because the 61850 protocol has better advantages and advancements, it will be the main standard in the field of smart grids in the future. Currently, the existing message analysis The device only supports the 61850 protocol, and the 103 protocol is still widely used and has a large stock. Therefore, there is an urgent need for a device that can support both the 103 protocol and the 61850 protocol message analysis
