An integrated test platform based on real-time simulation technology for substations

Abstract

The invention discloses a real-time simulation technique-based integrated testing platform for a substation. A data network board card is connected with a combining unit module and an intelligent terminal module respectively through cable connection wires; the combining unit module is connected with a message recording, analyzing and replaying device, a digital measuring and controlling device and a main transformer protecting module through specific sampling value optical fibers; the intelligent terminal module is connected with the message recording, analyzing and replaying device, the digital measuring and controlling device and the main transformer protecting module respectively through GOOSE (generic object oriented substation event) optical fibers; and the message recording, analyzing and replaying device, the digital measuring and controlling device and the main transformer protecting module are further connected with a monitoring backstage and a protecting sub-station through monitoring information switching equipment. Based on a real-time simulation system, a set of complete intelligent testing platform is formed through the signal control and transmission among interval layers and station control layer equipment by the combining unit module and the intelligent terminal module, and the detection result is accurate and effective, so that the testing platform is applicable to the simulation and testing fields of substations of various intelligent power grids.

Description

technical field [0001] The invention relates to a simulation test device, in particular to a simulation device using real-time simulation technology used in substations. Background technique [0002] With the increasing development of modernization, the smart grid technology for its supporting construction is also changing with each passing day. Among them, the requirements for the substation of the smart grid are getting higher and higher, not only to ensure real-time and comprehensive information collection and reliable and accurate command execution, but also With the significant and general improvement and gradual formation of substation informatization and automation, the command function of the advanced dispatching center can be fully realized, the execution ability can be improved, and the entire power grid can gradually form characteristics such as strong, self-healing, and flexible, and gradually develop into a smart grid. . [0003] With the construction of substa...
