Graphical display method of transparent LED display screen based on intelligent substation secondary circuit

Abstract

The invention relates to the field of design of intelligent substations and particularly relates to a graphical display method of a transparent LED display screen based on an intelligent substation secondary circuit. An LED transparent screen is installed on the upper portion in a screen cabinet of the intelligent substation. The SCD configuration file is loaded and analyzed through the intelligent switch; sV / GOOSE message configuration information of each IED is extracted; the industrial personal computer receives SV / GOOSE message configuration information from the intelligent switch; communication link message and physical connection and communication link and function loop matching are carried out on each IED; the matching result is transmitted to the network analysis equipment; the network analysis equipment is accessed to a real-time network of the intelligent substation to carry out online analysis and proofreading on SV / GOOSE message configuration information; an analysis resultis sent back to the industrial personal computer for graphical processing and then is transmitted to the LED transparent screen; the secondary circuit of the intelligent substation is displayed in agraphical display mode through the LED transparent screen, the LED transparent screen is used for replacing a traditional displayer to display the secondary circuit, and transformation and upgrading of a traditional station and popularization of a secondary circuit visualization scheme are facilitated.

Description

technical field [0001] The invention relates to the design field of intelligent substations, and specifically refers to a graphical display method of a transparent LED display screen based on a secondary circuit of an intelligent substation. Background technique [0002] The smart substation uses the IEC61850 standard as the basic communication network. Through this structure, the digital information can be effectively collected, the networked transmission of relevant data information can be realized, and the intelligent control of the operating system can be realized. The physical loop and the logical loop model together constitute the The complete secondary circuit model of the smart substation; in the traditional secondary system of the substation, the connection between the equipment is in the form of cables, and the detection of the entire substation is based on the design drawings and physical connections, which has the advantages of simple design and easy control With...
