Embodiment Construction

[0074] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0075] The maintenance of traditional relay protection equipment is generally carried out according to a fixed cycle, and it is impossible to realize the maintenance of relay protection equipment in a targeted and accurate manner, and the state of over-inspection and missed inspection occurs. Therefore, it is necessary to improve the accuracy of status monitoring o...

Abstract

The invention discloses a transformer substation relay protection equipment state monitoring method and system based on digital twinning, and the method comprises the steps: constructing a digital twinning scene map of a transformer substation through employing a digital twinning technology, and when relay protection equipment in a fault state is determined, visually positioning the corresponding fault relay protection equipment in the digital twinborn scene map, so that the problem that an existing two-dimensional logic view is blocked and cannot be visually reflected is solved, and the risk of misoperation of an operator during maintenance caused by positioning deviation is reduced. Meanwhile, by controlling the operation environment of the relay protection equipment, the normal operation environment is ensured, the adverse effect of the operation environment on the influence factor parameters of the relay protection equipment is reduced, and the actual reference value of each influence factor is improved, so that the accuracy of monitoring the state of the relay protection equipment is improved.

Description

technical field [0001] The present application relates to the technical field of relay protection equipment, and in particular to a digital twin-based method and system for monitoring the status of relay protection equipment in substations. Background technique [0002] Digital twins use physical models, Internet of Things sensors, and simulations to construct a mapping of the physical world in the virtual space that is exactly the same in the digital world through digital means. The deep integration of digital twins and 3D design in substations will greatly promote the digital transformation of its engineering design, construction, operation and maintenance links, which is of great significance to the high-quality construction of the national grid. [0003] The market operation and maintenance of substations is an important means to ensure the safe production of substations and improve the whole life cycle of equipment. Relay protection equipment is an important part of th...
