Development of an Intelligent Measuring System for Digital Substations

One of the directions of the transition to new technological order in the energy sector is the transition to the intelligent control of technological processes and commercial relations. It involves the creation of digital electrical substations of various voltage classes and actualizes the process of developing technical solutions in this direction of technological development. In the presented research, the transition to digital substations is analyzed as one of the directions of development of intelligent energy technologies. Possibilities of developing a measuring system for a software and hardware complex of digital substations based on a new type of digital measuring transformers are determined. It is proposed to use combined current and voltage measuring transformers as part of the measuring system of the 110 kV digital substation as information interaction equipment. A number of experimental researches and tests of prototypes of new digital measuring transformers, including high-voltage tests, experimental operation, verification of the measuring information for compliance with IEC 61850 and others were carried out. It is determined that the proposed technical solutions meet modern requirements for the software and hardware complex of digital substations.
