Establishment method of source-end database of secondary system of substation and corresponding method of virtual reality

Abstract

The invention discloses a transformer station secondary system source end database building method and a virtual-reality corresponding method; the virtual-reality corresponding method comprises the following steps: building an intelligent transformer station secondary system source end database; 2, according to the data in the source end database, built intelligent transformer station virtual loop connecting rules, equipment virtual terminal name, route and data set multiple-display, and virtual terminal one by one corresponding and real time storage principle, the loop connecting relation between intelligent equipment can be stored in a fourth linked list; 3, traversing virtual terminals in the fourth linked list, and extracting physical ports of corresponding equipment according to the virtual-reality corresponding principle; building a transformer station secondary system physical loop according to related information of the first, second and third linked lists; relating physical port connection according to virtual loop information flow, and finishing physical loop design according to a 2N principle, thus realizing intelligent transformer station secondary system virtual-reality corresponding relation.

Description

Technical field [0001] The invention belongs to the field of intelligent substations, in particular to a method for establishing a source-end database of a substation secondary system and a virtual-real corresponding method. Background technique [0002] Smart substations are based on the IEC61850 standard to realize digital network communication. Compared with conventional substations, optical signals are used for data transmission. A small amount of optical fiber replaces a large number of cables in traditional substations. A large number of real terminals in traditional substations disappear, and the information between secondary devices of smart stations is lost. Transmission relies on virtual terminals and virtual circuits. Logical nodes implement information transmission and function coordination based on the communication network, and the information flow relationship between functions is expressed through SCL language. Technological changes have caused fundamental changes...

Problems solved by technology

In the current application tools for intelligent station virtual terminal table and optical cable inventory design, virtual circuit design and physical device optical cable design are generally carried out in a completely separate or semi-automatic way, which causes designers to repeat the design of intelligent station information transmission At the same time, it is required to ensure the correct correspondence between the optical cable inventory and the virtual circuit through manual verification, which leads to a lot of repetitive work for designers, which is not only inefficient but also prone to errors
