NB-IoT based grid information physical fusion risk monitoring system and method

Abstract

The invention discloses a NB-IoT based grid information physical fusion risk monitoring system and method belonging to the field of grid information physical fusion system risk monitoring technology.The system is composed of a grid information physical fusion system environment monitoring module, a grid information physical fusion system error inductive module, a grid information physical fusionsystem state monitoring module, a NB-IoT communication base station, a data service platform and a user application terminal. The system realizes the risk monitoring application of the grid information physical fusion system based on narrowband Internet of Things by utilizing the advantages of narrowband Internet of Things technology and combining with rich sensor devices. By utilizing state conditions of the grid information physical fusion system obtained by the grid information physical fusion system state monitoring module, the risk monitoring method can timely discover the illegal movements of the grid information physical fusion system, over-limit pressure and various other abnormal conditions, ensures the security of the grid information physical fusion system, and has wide application value and a practical significance.

Description

Technical field [0001] The invention belongs to the technical field of risk monitoring of power grid cyber-physical integration systems, and in particular relates to a power grid cyber-physical integration risk monitoring system and method based on NB-IoT. Background technique [0002] In recent years, my country's power grid has developed rapidly and has become a huge power network covering the whole country and even the world. The power system is composed of two parts: the physical power grid system (primary system) and the information control system (secondary system), which precisely forms the cyber-physical system (CPS). Cyber-physical system is a multi-dimensional complex system with characteristics such as complexity, heterogeneity, deep integration, self-organization and self-adaptation, real-time and massiveness. These characteristics of cyber-physical systems also determine the concealment and severity of its risks. On the one hand, due to the complexity of cyber-physi...
