Intelligent substation communication network dynamic monitoring system and monitoring method thereof

Abstract

The invention provides a configuration-based intelligent substation communication network dynamic monitoring system and a monitoring method thereof. The monitoring system includes a network monitoring master station and at least one acquisition early warning terminal module which are connected through an Ethernet. The network monitoring master station is arranged at a station control layer to achieve state monitoring, anomaly alarm, anomaly early warning and management and maintenance of an intelligent substation communication network. Each acquisition early warning terminal module adopts the principle of local arrangement and abuts against network ports of a monitored network device for capturing, analyzing, determining and responding to packet information transmitted by the network ports. The technical scheme provided by the invention adopts a distributed manner to decompose the network acquisition data and data analysis, effectively solves the problems of huge amount of data acquisition of a conventional network monitoring analysis device and difficult data analysis, and achieves quick anomaly early warning and alarm of the network ports.

Description

technical field [0001] The invention relates to a system and method for testing and evaluating automation equipment / products of a power system, in particular to an intelligent substation communication network dynamic monitoring system and a monitoring method thereof. Background technique [0002] Compared with traditional substations, the biggest difference between smart substations is the use of network communication technology. The communication network of the smart substation belongs to the information intranet, which mainly uses a dedicated channel to collect information on the grid data, and is physically isolated from the external Internet. Therefore, most of the abnormalities and failures of the smart substation network are caused by defects in the internal equipment of the smart substation or human error. With the continuous deepening of the application of communication networks in smart substations, simple network security products or combinations can no longer mee...

With the continuous deepening of the application of communication networks in smart substations, simple network security products or combinations can no longer meet the needs of users

The functions set by the existing network packet analysis and recording devices applied to smart substations are more about recording than analysis, and most of the analysis methods used are still at the qualitative level, which cannot quickly and effectively capture network abnormalities and make timely and accurate analysis. To come up with countermeasures, only data records can be kept for technicians to analyze abnormal faults after they occur, and to summarize experience and lessons

Existing network packet analysis and recording devices still have problems such as huge amount of collected and stored data and difficulties in data analysis

The recording of a large amount of normal data not only occupies the limited storage space of the device and wastes a lot of hardware resources; it also makes it difficult to find and extract fault information data, which makes it difficult for technicians to deduce, analyze and analyze the occurrence and development process of abnormal faults afterwards.
