An intelligent substation and its intelligent secondary equipment testing system

Abstract

The invention discloses an intelligent substation and an intelligent secondary device testing system of the intelligent substation. The testing system comprises + / -220 / 110 V direct current power sources, a simulation device, multiple intelligent secondary device testing ends and simulation main wiring screens, wherein the simulation device comprises mimic-disconnecting switches and simulation switch blades and the mimic-disconnecting switches and the simulation switch blades are provided with input ends and output ends; each intelligent secondary device testing end is connected with one intelligent secondary device and the intelligent secondary device testing ends comprise first ports used for being electrically connected with the direct current power sources and second ports used for being electrically connected with the input ends of the mimic-disconnecting switches and the input ends of the simulation switch blades; the simulation main wiring screens are provided with the input ends which are connected with the output ends of the mimic-disconnecting switches and the output ends of the simulation switch blades, and the simulation main wiring screens are used for displaying the real-time state in tests of the intelligent secondary devices. The testing system conducts the tests in a stable and excellent workshop environment, and the integration test efficiency and the quality process of the intelligent secondary devices are improved.

Description

technical field [0001] The invention relates to the technical field of intelligent substations, and more specifically, relates to an intelligent substation and an intelligent secondary equipment testing system thereof. Background technique [0002] As an important part of smart grid, smart substation is the hub of smart grid energy transmission, the most important source of modern grid operation information, the execution place of grid intelligent operation control, and the foundation and key of building a strong smart grid. The smart substation has a unified data model and communication platform for the whole station. Digital communication is realized between the primary electrical equipment and the smart secondary equipment in the substation, and the interoperability between smart devices is realized on the basis of this platform. [0003] At present, there are more than a dozen types of intelligent secondary equipment used in intelligent substations, such as transformer p...

AI Technical Summary

Problems solved by technology

When the existing smart substation tests the smart secondary equipment on-site system in the substation project, it is limited and affected by factors such as harsh site conditions, cross-construction of civil engineering, tight construction schedule, and shortage of construction technical force. The test efficiency is low, and the smart secondary equipment The quality and craft of the equipment testing system are rough, which restricts the smooth operation of the substation project, which will cause a surge of operating defects in the later stage of the smart substation and other ills, threatening the normal and stable operation of the power grid
