Secondary Design of 110 kV Digital Substation Based on EEC 61850 Standard

With the development of the smart grid, the digital substation as a smart grid node is playing a more important role increasingly. This article takes the design of the 110 kV digital substation as an example, and analyzes the concept and features of the digital substation. The methods to construct digital substations based on IEC61850 three-layer network structure are explained from the perspective of secondary design. Comparing with normal substations, the changes of the primary equipments, seeondary equipments and networks in the secondary design of digital substations are analyzed, and some notices and requirements for the secondary design of digital substations are proposed for the reference of relevant engineering designers.
