Initiative risk protection system for variable flow type vector control device of high-capacity thyristor

Abstract

An initiative risk protection system for a variable flow type vector control device of a high-capacity thyristor comprises a chip-level encryption and decryption control unit, a multisource / heterogeneous type industrial control network gateway, a compact type embedding type processing unit, an embedding type analyzing system, a risk evaluation and typical operation state analyzing unit and the like. The chip-level encryption and decryption control unit is used for supplying high-capacity synchronous motor rotor mechanical positions and rotating speed data information. The compact type embedding type processing unit is used for performing flow control and filtering on dynamic data of alternating current. The embedding type analyzing system is used for analyzing a current regulating type expert type rule base within half cycle of natural commutation. The risk evaluation and typical operation state analyzing unit is used for obtaining real-time information of voltage feedforward compensation and air gap flux linkage tracks. The initiative risk protection system aims at solving the problem of security holes, attack and virus invasion of industrial control networks of main mills and the like in the steel and iron industry, can perform initiative protection and remote real-time monitoring, and is safe, reliable, autonomous and controllable. An industrial equipment level information security control technique of the initiative risk protection system is further provided.

Description

technical field [0001] The invention belongs to the field of industrial automation information security, and relates to an active danger prevention technology for metallurgical process industry, basic automation level, and large-capacity thyristor variable flow vector control equipment, and for security loopholes in industrial control networks of equipment such as main rolling mills in the iron and steel industry, Attack, virus intrusion, active defense, remote real-time monitoring of anti-danger devices and industrial equipment-level information security control technology. Background technique [0002] Since 2010, the "Stuxnet" virus and its derivative viruses targeting industrial control systems have emerged continuously, bringing huge hidden dangers to the industrial infrastructure of various countries, which has attracted great attention from all countries. The ultimate goal of these viruses is not to obtain user data or economic benefits, but to target the critical...

Problems solved by technology

[0003] At present, foreign companies such as TOFINO and GE have some products for real-time fault analysis, prediction and optimized operation system. They have just entered the domestic market and have not yet formed a monopoly. At the same time, it is particularly important that these foreign products are only for the goal of defense in depth. , ANSI / ISA-99 area and pipeline protection model firewalls, including products such as one-way gatekeepers and industrial firewalls that are widely used in China at present, none of them can meet the industrial equipment level information security control of basic automation level main rolling mills and other equipment in metallurgical processes the actual requirements of

Therefore, if information security control issues such as security vulnerabilities, attacks, and virus intrusions for large-scale equipment are not effectively resolved, it will definitely bring a devastating blow to the country's major infrastructure such as industry and national defense.
