The Research And Application Of Electronic Instrument Transformer In Smart Substation

Smart substation adopts advanced, reliable, integration, low carbon, environmental protection of intelligent equipment to the total information digitization, communication platform networking, information sharing standard into basic requirement, and automatically complete information collection, measurement, control, protection, measurement and monitoring and other basic functions, and can according to need support network real-time automatic control, intelligent adjustment, online analysis and decision, cooperative interaction and other senior function, realization and adjacent substation, power grid scheduling etc interactive substation.This paper has a deep study demonstrates intelligence in the electronic instrument transformer substation configuration of the selection, merge unit, sample value transmission and synchronization, electricity measurement selection, to analyze the effect of secondary system, analyzed the adaptability of PMU, risk identification and coping etc, and application of electronic transformer and the conventional transformer economic comparison.This article for the active type electronic transformer brings the problems are proposed solutions and analysis the type transformer is particularly suitable for HGIS and GIS equipment, for the application of the device, so this paper thinks to unblock the application of 500kV Wuning Substation become active type electronic transformer is relatively optimal scheme.Magneto-optic glass type and optical fiber type electronic current transformer exist temperature influence, birefringence effect, especially long-term stablity need scale applications, long time running experience can be verified, accordingly, the proposal is to take further pilot to verify electronic transformer passive type the operation stability.
