IoT-PMU. How to improve the observability on the Distribution Networks

Abstract

This paper addresses the introduction of IoT-PMU device in the distribution networks as an extra source of information. The IoT-PMU concept combines Phasor Measurement Unit (PMU) functionalities with the ability to communicate by protocols used in Internet of Things (IoT), the design is implemented in a minimal functional device. The presented implementation is hardware agnostic and could be transfer to any general-purpose hardware, could even be included as an additional function in the current protection relay product. This paper shows the performance of the IoT-PMU concept regarding phasor, magnitude, angle and frequency measurements accuracy.
