Embodiment 1

[0050] An embodiment of the present invention provides an electric power industry control system, such as figure 1 shown, including:

[0051] A plurality of power distribution terminals 1, a network communication module 2, a security access module 3, a main control station 4, a production control module 5, and an electric power industry management platform 6.

[0052] Among them, a plurality of power distribution terminals 1 are distributed and arranged in different areas, and each power distribution terminal 1 is used to perform grid information interaction with user terminals in the area to which it belongs. The power distribution terminal 1 here serves as the junction point for the interaction between the power supply department and the user terminal, so it can be considered as the terminal point for the information interaction of the distribution network.

[0053] The network communication module 2 is connected with each power distribution terminal 1 . The network communic...

Embodiment 2

[0075] An embodiment of the present invention provides a power industry control method for the secure access module in Embodiment 1, such as figure 2 shown, including:

[0076] Step S21: Obtain network communication messages uploaded by each power distribution terminal.

[0077] Step S22: identifying whether the traffic data size of the network communication packets exceeds a preset threshold within a preset time. Specifically, the traffic data size of the network communication message corresponds to the preset standard threshold within the preset period; when the traffic data size of the network communication message does not exceed the preset threshold, it means that the traffic data size of the network communication message meets the requirements, It complies with safety standards.

[0078] Step S23: When the traffic data size of the network communication message exceeds the preset threshold, send the first alarm message to the electric power industry management platform...

Embodiment 3

[0084] The embodiment of the present invention provides a power industry control method, which is used in the production control module in Embodiment 1, such as image 3 shown, including:

[0085] Step S31: Obtain the power grid control command issued by the main control station.

[0086] Step S32: identifying whether the data information corresponding to the grid control command is abnormal.

[0087] Step S33: When the data information corresponding to the main control instruction is abnormal, send the third alarm information to the electric power industry management platform.

[0088] For the power industry control method in the embodiment of the present invention, and the specific safety monitoring content of the power industry control method in this embodiment, please refer to the specific description of the security access module in Embodiment 1, and will not be repeated here. The production control module identifies the abnormal grid control commands to determine the g...

Abstract

The invention discloses an electric power industry control system and control method. The system comprises a plurality of power distribution terminals, a network communication module, a security access module, a master control station and a production control module, the flow data size of the network communication message of each power distribution terminal is identified through the security access module, first alarm information is generated for the flow data size which does not meet the requirement, the target network address of each power distribution terminal is identified, second alarm information is generated for the target network address which does not meet the requirement, therefore, the information security of the security access module in the power industrial control system canbe ensured, the potential safety hazard in an electric power industrial control system is reduced, normal work of the power industrial control system is ensured, the production control module is usedfor identifying an abnormal power grid control instruction to determine the power grid control instruction which does not meet the requirement, so that third alarm information is generated, and whether the power grid control instruction issued by the main control station has potential safety hazards or not can be ensured.

Description

technical field [0001] The invention relates to the technical field of electric power industry control, in particular to an electric power industry control system and a control method. Background technique [0002] With the rapid development of power network technology, the power industrial control system can realize the quality inspection and testing of automation equipment or communication equipment, or the industrial monitoring of distribution network operation control or power grid operation terminals, thereby satisfying the diverse needs of regional users. service requirements. [0003] At present, as the interaction between power distribution terminals and power industry control systems becomes more and more frequent, power distribution terminals with illegal identities often log in or operate illegally or illegally access power industry control systems, and then illegally attack power industry control systems through malicious behavior. It leads to serious damage to ...
