A digital power grid system and method based on real power grid topology analysis and a security knowledge base

Abstract

The invention provides a digital power grid system and method based on real power grid topology analysis and a safety knowledge base. The digital power grid system includes a software platform, a hardware platform, a server and a data processing system, an operation safety management and control module and a cloud platform; An actual power grid model is established based on GIS map information through a GIS system; After an actual power grid model is established by the GIS system, topology analysis based on the actual operation mode of the whole power grid is carried out in the server throughthe power grid topology analysis module, and the cloud platform carries out real-time online power grid operation and work safety check through the formed operation safety knowledge base. According tothe invention, the safety of all work in the power grid can be calculated in real time through the actual power grid model established based on the GIS map information; An operation safety knowledgebase is formed through large-scale power grid topology analysis and logic operation basis, electrical rules adapting to objective laws of electrical equipment and some management rules, and the working efficiency and safety of the power grid are greatly improved.

Description

technical field [0001] The invention relates to the field of electric power engineering, in particular to a digital power grid system and method based on real power grid topology analysis and a safety knowledge base. Background technique [0002] In the production process of the power system, in order to ensure personal safety and prevent electrical misoperation, the staff must strictly abide by various safety rules and regulations within the power system. Among them, the "two votes" system is an important system to ensure personal safety. "Two votes" means "Operation Ticket" and "Work Ticket", "Operation Ticket" is mainly used to standardize operation steps and prevent operational errors, so as to ensure the safety of operators; "Work Ticket" is mainly used to standardize the scope of power outages and safety measures Incorrect power failure range and other situations occur, so as to ensure the safety of workers on electrical equipment. [0003] The function of the existin...

Problems solved by technology

[0003] The function of the existing operation ticket system is limited to manual ticket filling, and does not have the function of "graphical invoicing and intelligent verification". The invoicing work is not only time-consuming and laborious, but also requires manual checks on the correctness of the invoicing. The operation ticket is not used in the process. In the actual use process, the issued tickets are only used as written basis for personnel operations, and the subjective error is relatively high; the current anti-misoperation locking system used in the power grid has no anti-misoperation rules. Extensive adaptability. For the types of operations that are not considered in the error prevention rules, the system will give wrong results, resulting in the failure of the operation. It is not suitable for the network-wide anti-error operation requirements, and a large amount of additional hardware needs to be configured , which brings a lot of workload to the operation and maintenance personnel, resulting in a great waste of resources; at the same time, the current blocking system for preventing misoperation does not have anti-misjudgment based on the real-time operation mode of the power grid, and most of them are stand-alone working modes, which do not meet the requirements of the power industry. Therefore, the present invention proposes a digital grid system and method based on real grid topology analysis and security knowledge base to solve the deficiencies in the prior art
