Research On The Digital Substation Of Electronic Transformer And Digital Interfaces

With the rapid development of smart grid, substation digital key is a seamless connection between the spacer layer between information sharing and intelligent electronic devices interoperable. The electronic transformer is the source of the basic voltage and current signals to meet the new requirements for the development of digital substation transformer has an important practical value.Analyzed in the analysis of the smart grid and the needs of digital substation based on IEC60044-7/8and IEC61850standard transformer. A new electronic transformer design based on the IEC61850standard. Contrast to the existing electronic transformer, focusing on the new electronic transformer low voltage side functions to build a mapping based on the IEC61850standard low-voltage side of the information model abstract communication service interface and communications. Finally the virtual instrument technology to achieve the functions of each module of the electronic transformer, and verify the feasibility of this.
