In recent years, there has been a rapid shift towards a fully digital paradigm in electrical substations. This shift is driven by the need for greater interoperability between different instruments and control actions, which is facilitated by the IEC 61850 series of standards. In this paper, we specifically focus on Phasor Measurement Units (PMUs) and their role in this digital transformation. One of the challenges in adopting high-performance wired communication standards such as Ethernet and TSN is the cost associated with wiring over long distances between substations. To overcome this limitation, we explore the feasibility of utilizing a 5G communication infrastructure to transmit PMU measurements. Our study simulates a real-world distribution network and assesses the worst-case latency between PMUs and Phasor Data Concentrator (PDC) by scaling the number of PMUs considered. With a mean communication latency of 20 ms, the 5G communication infrastructure proves to be a valuable solution, particularly in distribution networks where the monitoring applications rely on update rates in the order of few tens of ms.

Abstract
In recent years, there has been a rapid shift towards a fully digital paradigm in electrical substations. This shift is driven by the need for greater interoperability between different instruments and control actions, which is facilitated by the IEC 61850 series of standards. In this paper, we specifically focus on Phasor Measurement Units (PMUs) and their role in this digital transformation. One of the challenges in adopting high-performance wired communication standards such as Ethernet and TSN is the cost associated with wiring over long distances between substations. To overcome this limitation, we explore the feasibility of utilizing a 5G communication infrastructure to transmit PMU measurements. Our study simulates a real-world distribution network and assesses the worst-case latency between PMUs and Phasor Data Concentrator (PDC) by scaling the number of PMUs considered. With a mean communication latency of 20 ms, the 5G communication infrastructure proves to be a valuable solution, particularly in distribution networks where the monitoring applications rely on update rates in the order of few tens of ms.File | Dimensione | Formato | |
