Intelligent transformer substation simulation switch, equipment and method

Abstract

The invention discloses an intelligent transformer substation simulation switch, equipment and a method. The intelligent transformer substation simulation switch comprises a control loop and a direct-current power supply loop, a position output contact, an analog quantity control loop and a GOOSE and SV parsing loop which are connected with the control loop; the GOOSE and SV parsing loop is connected with a GOOSE receiving and sending optical port and an SV receiving optical port; the control loop is connected with a closing coil and a opening coil and used for controlling opening and closing of a three-phase switch in a manual mode or automatically controlling opening and closing of the three-phase switch according to received opening and closing commands of the analog quantity control loop and the GOOSE and SV parsing loop. The intelligent transformer substation simulation switch has the advantages that the intelligent optical ports and a switch operating mechanism are integrated, and therefore the intelligent simulation switch can directly control the three-phase switch in the manual mode and also can automatically control the three-phase switch through the control commands sent by the analog quantity control loop or the GOOSE and SV parsing loop.

Description

technical field [0001] The invention relates to the technical field of simulation switches, in particular to an intelligent substation simulation switch, equipment and method. Background technique [0002] The substation integrated automation system is an intelligent complete system, which is the product of the combination of the dispatching automation station equipment RTU and the substation microcomputer protection device after the development to a certain extent. It is developed on the basis of computer technology and network communication technology. of. Starting from the substation as a whole, it integrates the protection, monitoring, measurement, signal, telecontrol, communication, DC and five prevention functions of circuit breakers, transformers, isolating switches and other equipment to achieve resource sharing and avoid duplication of functions. More reliable operation and convenient management of automation module devices, and a comprehensive automation system th...

AI Technical Summary

Problems solved by technology

Most of the existing simulation switches are relatively bulky, small in size and not comprehensive in functions, such as no position output contacts or only three-phase on-off and no single-phase on-off, etc.

Moreover, the existing simulation switches are all used for conventional stations, and do not have functions such as GOOSE, SV input, and GOOSE output.
