Description

Technical Field

[0001] The present invention relates to the technical field of monitoring systems, and in particular to a monitoring system and method for safety risks of power grid infrastructure. Background Art

[0002] Grid infrastructure, the full name of which is grid infrastructure construction, is the construction and development of power networks used to support and guarantee functions such as power transmission, distribution and dispatching. Grid infrastructure includes the entire process from power generation, transmission, transformation to end users, ensuring that electric energy can be stably and efficiently distributed to various regions and users. Grid infrastructure is one of the key infrastructures for modern economic and social development, involving a wide range of content, including the production, transmission, distribution, dispatching and construction of related supporting facilities.

[0003] The safety risks of power grid infrastructure involve many aspects, including equipment, environment, personnel, and technology. Therefore, the safety risk monitoring of power grid infrastructure is a key link in ensuring the stability and safety of power grid operation. Through scientific and systematic monitoring methods, potential problems can be discovered in advance, risks can be prevented, and the normal operation of power facilities can be ensured. At present, the main methods and technical measures for monitoring the safety risks of power grid infrastructure include: equipment status monitoring, power grid load and operation status monitoring, intelligent monitoring system, disaster prevention and mitigation monitoring, network security monitoring, power grid facility inspection and monitoring, human resources and operation safety monitoring, emergency response and plan management. It can be seen that the conventional method of monitoring the safety risks of power grid infrastructure still adopts the conventional method from monitoring to response. However, this method still has the following shortcomings:

[0004] Only simple mathematical statistics can be performed on a single type of safety risk, and the correlation between safety risks is separated, which makes the safety risks too simplified and cannot be fully applied to large-scale power generation, transformation, transmission and distribution power grid systems. Summary of the invention

[0005] In order to solve the technical problems existing in the background technology, the present invention provides a monitoring system and method for safety risks of power grid infrastructure, which performs digitized statistics on various types of safety risks, making the safety risk statistics more reasonable and more practical for the current power grid system.
