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 showcased 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.

电网中的停电被迫监视电网状况。相量测量单元（PMU）在广域测量系统（WAMS）中已成为必然。由于非递归DFT算法具有很高的稳定性，因此电流和电压相量的连续测量变得更加可靠。使用NI LabVIEW Professional开发系统，可以在软件和硬件中实现PMU的设计和建模。本文的新颖之处在于，通过使用适度设计的Analog Discovery 2实现了便携式相量测量单元的连续监视和实时实施。结果得到验证，并且所提出的实现比常规系统更具成本效益。
