Intelligent apparatus GOOSE virtual terminal collocation method for digitized transforming plant

Abstract

The invention relates to a method for configurating a virtual terminal of an intelligent device GOOSE in a digitalized substation, comprising the following steps: at least respectively defining the opening-inserting logic 1-i of the intelligent device as virtual terminals IN1-INi, and defining the opening-outgoing logic 1-j as virtual terminals OUT1-OUTj; expressing configuration of each intelligent device GOOSE in the form of connection in accordance with the principles of relay protection based on the intelligent device; respectively defining the terminal logic connection 1-k as LL1-LLk; arranging and re-expressing the configuration of the intelligent devices GOOSE in form of a list according to the logic connection based on virtual terminal logic connection; a GOOSE figuration list consists of the virtual terminal logic connection and the corresponding starting point and end point, wherein, the logic connection consists of two lists of the logic connection number LLk and the logic connection name. In this invention, the method can express network-transmission-based GOOSE digital signals in the form of the virtual terminals, so that personnel in charge of designing, construction, debugging, operation and maintenance of the intelligent device can intuitively read the opening-inserting logic, the opening-outgoing logic, exit logic and the like; in addition, the method can successfully solve the problem of difficult expression of GOOSE protective configuration on the drawing board, thus realizing construction according to the drawing, greatly improving efficiency of construction and debugging, meeting the requirement that 'digitalized substation is constructed by designing'.

Description

technical field [0001] The invention relates to a method for configuring GOOSE virtual terminals of a digital substation intelligent device. Background technique [0002] The digital substation takes the primary and secondary equipment of the substation as the digital object, and based on the high-speed network communication platform, realizes information sharing and interoperability through the standardization of digital information, and realizes relay protection and data management based on network data. It is a substation that meets the requirements of modern substation construction such as safety, stability, and construction economy. [0003] With the rapid and continuous development of power loads, the gradual formation of large-capacity and super-large system grids, and the increasing requirements for grid security, stability, reliability, control, and information interaction, digital power systems have become an inevitable direction for the development of power system...
