A method for safe operation and maintenance gateway of electric power secondary system remote operation and maintenance

Abstract

The invention discloses a safe operation and maintenance gateway method for remote operation and maintenance of a power secondary system, which includes monitoring the operation and maintenance safety of the system through a matching special operation and maintenance tool on the operation and maintenance terminal; the motion control terminal performs monitoring according to the monitoring situation The motion execution end performs real-time control; the operation and maintenance terminal and the motion execution end provide network connection firewall, routing and gateway services through the operation and maintenance gateway. The invention integrates the login process through the gateway control system, and through the source account mapping record table mechanism, the account management is well integrated into the security inspection process of the entire security operation and maintenance, and the management of the protection rules of the firewall is well integrated, forming a A complete authorization system, and then through the gateway or NAT mode of the operation and maintenance gateway, the operation request / network access of the operation and maintenance special tool running on the operation and maintenance terminal is safely delivered to the target address.

Description

Technical field [0001] The present invention belongs to the technical field of power, particularly relates to a method for remote secondary power system operation and maintenance operation and maintenance of the security gateway. Background technique [0002] Power system by the power generation, power transmission, transformation, distribution, and the corresponding electrical equipment of auxiliary systems. [0003] Electrical power system equipment has a definition of a distinguishing device, the second device. [0004] Equipment (also known as the master device), a main body constituting the power system, which is the direct production, transmission and distribution of electric energy, comprising: a generator, transformer, electrical switch, power lines, transformers, surge arresters and the like, comprising a high voltage characterized by high current. [0005] Equipment according to purpose and function of the interconnecting circuit, called a primary circuit or wiring or a...

AI Technical Summary

Problems solved by technology

[0022] At present, with the increase of network security risks such as viruses, Trojan horses, malicious attacks, etc., in the operation and maintenance process of the telecontrol system of the power secondary system, the existing technical specifications, operating procedures, and safety protection measures have lagged behind, and maintenance is prone to occur. Computer (control terminal) security out of control, internal and external network isolation failure, virus carrying injection, attack program touching private internal network and other security incidents

[0023] After the actual investigation of the electric power industry and the retrieval of related patents, it is found that the current operation and maintenance management of the secondary power system, especially the operation and maintenance management of the telecontrol system, its security mechanism has lagged behind the security technology of the current IT industry. development, the technical options for normalized security management are quite lacking
