Information anomaly detection system and method for lightweight intelligent substation

Abstract

The invention provides an information anomaly detection system and method for a lightweight intelligent substation, and the system configuration module is used for analyzing a substation configurationfile, comparing the substation configuration file with captured message configuration information, and obtaining all whole-frame message information of the intelligent substation; a sniffing module is used for acquiring message information flowing through the system in real time, and screening, classifying and storing the message information; a detection alarm module is used for receiving the data packets GOOSE, SMV and MMS, and comparing the data packets GOOSE, SMV and MMS with a preset abnormal rule set to give an alarm; and a management module is used for realizing user permission endowing, duty log recording and system data recording. According to the invention, abnormity detection alarm can be carried out on the message information of the system in combination with the current intelligent power transformation configuration file; the information operation state is fed back, multi-dimensional classification recording of the abnormal information is realized, operation and maintenance work personnel can be assisted to carry out online analysis, summarization and conclusion of the abnormal information can be carried out afterwards, and the method has certain application values inengineering.

Description

technical field [0001] The invention relates to an intelligent detection technology of an electrical system, in particular to a light-weight intelligent substation-oriented information anomaly detection system and a method thereof. Background technique [0002] The smart substation is based on the IEC61850 protocol, a new type of substation that can share information between the smart electrical devices inside the substation, and can interoperate between the smart electrical devices inside the substation. The intelligentization of substations makes the original relative closure of the smart substation network broken, and the information security of smart substations has become the object of widespread concern in the academic and engineering circles. In order to ensure the normal operation of smart substations and assist operation and maintenance staff in fault location and fault analysis, many researchers are focusing on research on ensuring the safe operation of smart subst...
