Low-Cost Real-Time Design and Implementation of Phasor Measurement Unit using Analog Discovery

摘要

The blackouts in the power grid are forced to premonitor the conditions of the grid. Phasor Measurement Units (PMU) have become highly inevitable in the Wide Area Measurement System (WAMS). Continuous measurement of current and voltage phasors has become more reliable owing to very high stability show-cased by Non-recursive DFT algorithm. Design and Modelling of PMU are implemented both in software and hardware using NI LabVIEW Professional development system. The novelty in this paper is that the continuous monitoring and real-time implementation of portable Phasor Measurement Unit is achieved by using Analog Discovery 2 with modest design. The results are validated, and the proposed implementation is more cost effective than the conventional system. (C) 2020 Elsevier B.V. All rights reserved.
