Smart power grid embedded device network detection assessment system and detection assessment method

Abstract

The invention discloses a smart power grid embedded device network detection assessment system which comprises a special network safety detection device, a shadow machine and a power system safety monitoring center. The special network safety detection device analyzes and filters various kinds of network data packs; the shadow machine detects the network state and changes of a host state of the embedded system when the embedded system is under network attack and sends the network state and host station information to the power system safety monitoring center; the power system safety monitoring center obtains a safety detection result by means of multi-dimensional property comprehensive measurement based on platform configuration property measurement, platform operation property measurement and user authentication property measurement. On the premise that normal work of the embedded system is not influenced, real-time and dynamic safety detection and assessment can be carried out on known or unknown power system network attacks quickly and accurately by means of the shadow machine.

Description

technical field [0001] The invention relates to the field of safety testing of smart grid embedded devices, in particular to a smart grid embedded device network detection and evaluation system and detection and evaluation method. Background technique [0002] With the rise of the Internet of Things industry, in the smart grid, all kinds of sensors and control devices are embedded systems, which are widely used in the main links of power generation, power transmission, power transformation, power distribution and user power consumption. In addition to business measurement and transmission functions, the embedded system also plays a core business operation control function. For example, the multi-rate electric energy metering management unit at the user level, the transformer oil temperature sensor, voltage and current transmitter, relay protection device, fault recording, line protection, fault distance measuring device at the equipment layer, and digital recording in the co...
