REALIZATION OF SMART MV/LV SUBSTATION THROUGH THE CONCEPT OF MICRO RTU

摘要

This paper presents a concept of smart MV/LV substation using the multi-purpose and multi-communication micro RTU device. The role of the developed micro RTU is to collect and analyze measured data in the substation, and to realize the two-way communication with the Control centre. Authors present a complete solution for the transformer monitoring, with the description of two main components: multi-functional power analyser and micro RTU. Main functions of this system are analysed, including the description of input and output values, local automation functions and supported communication protocol and interfaces.
