Problems solved by technology

[0002] At present, with the rapid development and application of distribution automation technology, some county-level distribution automation systems that do not have optical fiber communication conditions use public network communication methods (GPRS / CDMA / TD-SCDMA / 230MHz, etc.) to transmit control commands, resulting in The system faces the risk of attacks from the public network, affecting the safe and stable operation of the distribution network. At the same time, there are sub-station terminals intruding into the main station, causing a wider range of security threats

Abstract

The invention discloses a control system for distribution network security, including a master station, the master station includes a public network front-end processor and a private line front-end processor, and the public network front-end processor is connected to a 3G/4G wireless public network For the above-mentioned substation terminals, the public network front-end processor includes a signature module and pre-installed master station private key, and the dedicated line front-end processor includes a signature module and pre-installed master station private key, and more than one sub-station terminal is pre-installed with a master station public key and the authentication module, the signature module of the public network front-end processor is connected to the authentication module through 3G/4G, and the signature module in the private line front-end processor is connected to the authentication module of the substation terminal. During the implementation process, it is necessary to modify the front-end computer of the master station of the automation system, install the private key and signature module of the master station, and realize the digital signature of the control command (or parameter setting) message. Prevent attacks on sub-stations through the public network, causing interruption of user power supply; at the same time, prevent (something) from invading the main station through the public network and user terminals, causing a wider range of security risks.

Description

technical field [0001] The invention relates to a power system, in particular to a control system for distribution network security. Background technique [0002] At present, with the rapid development and application of distribution automation technology, some county-level distribution automation systems that do not have optical fiber communication conditions use public network communication methods (GPRS / CDMA / TD-SCDMA / 230MHz, etc.) to transmit control commands, resulting in The system faces the risk of attacks from the public network, affecting the safe and stable operation of the distribution network. At the same time, there are sub-station terminals intruding into the main station, causing a wider range of security threats. [0003] Therefore, it is a technical problem to be solved urgently by those skilled in the art to provide a control system for power distribution network security to improve the safety and stability of power grid control.
