Power grid object access control device capable of realizing safety configuration and access of power grid model data

Abstract

The invention aims at providing a power grid object access control device capable of realizing safety configuration and access of power grid model data. The device is characterized by including a layered division and security permission configuration module of the power grid model data and an access security control module; the layered division and security permission configuration module realizes layered division and security permission configuration of the power grid model data; and the access security control module realizes access security control of a power grid model. Through hierarchical organization of the power grid model according to region, sub regions, power stations and voltage levels, classification of other power grid objects such as devices, terminals and measurement devices and the like into corresponding hierarchies according to incidence relations, and combination of access permissions of system access users for the data and the hierarchical result, the device realizes access security control which is appropriate in granularity and enables security access of operation data of the whole power grid to be corresponding to a management system which is currently in effect.

Description

technical field [0001] The invention relates to secure access and control of grid data, in particular to providing a grid object access control device capable of realizing secure configuration and access to grid model data. Background technique [0002] The production management of the power system usually divides the power grid into multiple sub-networks based on the distribution of the power grid, the voltage level of the power grid, etc. Provincial dispatching, local dispatching, county dispatching and other multi-level dispatching centers; at the same level, the power grid at the same level can be divided into multiple dispatching centers according to the geographical distribution of the power grid; finally a set of "unified dispatching, hierarchical management "Management system. [0003] In recent years, with the development of power grid business and the improvement of management requirements, the requirements for information sharing and collaboration between various...

Problems solved by technology

[0006] The disadvantage of database-based security access control is that the granularity of security control does not match the actual power system. The power system adopts layered and sub-regional security control, while database security management, such as relational database systems, is oriented to tables and table records. ; This leads to complex implementation of corresponding security controls and low efficiency of access control

[0011] The disadvantage of the security access control directly based on the OPC UA server grid model nodes is that the OPC UA nodes are used as the basis for security control. For the power grid model with millions of OPC UA nodes, the security control granularity is too fine. The corresponding system configuration and maintenance workload is heavy

Moreover, because it cannot match the current management method of power grid production management, it is difficult to automatically perform security configuration migration when the power grid model or power grid dispatching authority changes
