Public network safety access method for new energy power plant

Abstract

The invention discloses a public network safety access method for a new energy power plant, which comprises the following steps of: carrying out safety partitioning on a network in the new energy power plant, and placing each service system in safety regions; carrying out transverse separation between each safety region by a hardware measure; connecting the safety region with the lowest safety level in the new energy power plant with a public network; and when accessing the new energy power plant by the internet, verifying a user identity by an authority certificate based on satisfaction, andpassing verification, carrying out access on the safety region with the lowest safety level in the new energy power plant. By the public network safety access method disclosed by the invention, not only is a safety risk from the public network, which an internal network system of the new energy power plant directly faces, avoided, but also the ability of preventing a public network attack is greatly improved.

Description

technical field [0001] The invention relates to a public network security access method, in particular to a public network security access method for new energy power plants. Background technique [0002] In recent years, new energy industries such as wind power and photovoltaics have developed rapidly, and new energy installed capacity in power grids has shown explosive growth. With the large-scale access of new energy power plant business to the dispatching data network, more and more business systems connected to the public network are connected. However, my country's new energy power plants are mainly built in sparsely populated locations with harsh geographical environments. In addition, the new energy power plants themselves are widely distributed, so manual maintenance is very difficult, and most of them use remote access for control and monitoring. [0003] Taking wind farms as an example, wind power companies are located in cities far from wind farms. The managemen...

AI Technical Summary

Problems solved by technology

It can be seen that the security protection of the secondary system of new energy power plants is mainly based on the security protection of the internal network. At the network border connected to the public network, most of the security protection measures are only a firewall, and the protection capability is very weak.
