Research on the Secondary Interface of Electronic Transformers in Smart Substation

Abstract:

According to the requirements of smart substation metering system, a digital interface based on IEC 61850 specification is given, then the functional model of the merging unit is discussed. Meanwhile, according to the actual situation, the author proposes an analog output interface, in order to fit with traditional substation secondary equipment. Then the solution based on TMS320F28335 digital control platform is described, for which the voltage control module of the software and hardware circuits are discussed in detail. The experimental data shows that the proposed merging unit and analog voltage output interface can meet the accuracy standard of electronic transformer in the smart substation.
