Method of safety operation and maintenance gateway for telecontrol operation and maintenance of power secondary system

Abstract

The invention discloses a method of a safety operation and maintenance gateway for telecontrol operation and maintenance of a power secondary system. The method comprises the following steps: performing operation and maintenance safety monitoring on the system through a matched special operation and maintenance tool on an operation and maintenance terminal; performing real-time control on the motion execution end by the motion control end according to the monitoring condition; and providing firewall, routing and gateway services of network connection between the operation and maintenance terminal and the motion execution terminal through the operation and maintenance gateway. According to the method, the login process is integrated through the gateway control system; a record table is mapped through a source account number mechanism; account management is well integrated into the whole security check process of security operation and maintenance; according to the method and the system, the management of the protection rule of the firewall is well integrated, a complete authorization system is formed, and then the operation request / network access of the special operation and maintenance tool running on the operation and maintenance terminal is safely sent to the target address through the gateway or the NAT mode of the operation and maintenance gateway.

Description

technical field [0001] The invention belongs to the field of electric power technology, and in particular relates to a method for a safe operation and maintenance gateway for remote operation and maintenance of a power secondary system. Background technique [0002] The power system consists of power generation, power transmission, power transformation, power distribution, power consumption equipment and corresponding auxiliary systems. [0003] The electrical equipment of the power system has the definition of primary equipment and secondary equipment. [0004] Primary equipment (also known as main equipment) is the main body of the power system. It is the equipment that directly produces, transmits and distributes electric energy, including: generators, transformers, switching devices, power lines, transformers, lightning arresters, etc., with high voltage , High current characteristics. [0005] The circuit formed by the interconnection of primary equipment according to...

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
