Abstract

The invention discloses a DTU safety monitoring system based on power consumption information. The DTU safety monitoring system comprises a data acquisition module and an information processing module, wherein the data acquisition module is used for acquiring electrical power consumption information of terminal equipment and converting analog quantity into digital quantity so as to acquire binarydata flow and transmit the binary data flow to the information processing module; and the information processing module is used for carrying out feature extraction on the information transmitted by the data acquisition module, carrying out model training and classification, and finally predicting faults and fault types. Based on the internal power consumption information of the power terminal, thecharacteristics of propagation conversion and coordination consistency of the power consumption information and the relevance between the power consumption information and the system safety are researched, the complex process of data processing and analysis is reduced on the premise of ensuring the monitoring accuracy, and the implementation of safety monitoring of the power terminal is simplified to a certain extent.

Description

technical field [0001] The invention belongs to the field of safety monitoring of electric power industrial control terminals of smart grids, and relates to a technology for monitoring the working state of electric power terminals, in particular to a DTU (Data Transfer Unit) based on power consumption information. Background technique [0002] With the rapid development of energy Internet and smart grid projects, the interaction between power grids and market users has increased, the amount of distributed power generation has continued to increase, and the requirements for power supply quality have increased. The control method is used to realize the collection of data, the detection of equipment and the adjustment of parameters, so as to achieve the goals of safety, reliability and economical efficiency of the power grid. [0003] The interaction between supply and demand of multiple users also makes power terminals face the problem of diversified attacks. Therefore, a real...
