AI总结:

本文设计并验证了一种平均功耗仅30.8 mW的极低功耗单相PMU,比现有方案低一到两个数量级,可依靠电池或太阳能供电,并通过IEC/IEEE 60255-118-1标准测试验证精度,有望推动PMU在配电网中的大规模部署。

摘要:

相量测量单元(PMUs)在其安装位置提供电力系统的高分辨率视图。因此,希望在低压配电线路中批量部署PMU。然而,PMU/微型PMU的功耗在瓦特(W)量级,这导致它们需要外部电源供电,进而增加了总体成本。本文详细介绍了一种PMU的硬件设计,该PMU能够测量和报告单相系统的电压和电流相量,平均功耗仅为30.8 mW——比现有学术和商用PMU低一到两个数量级。这使得所提出的PMU能够使用11 Wh电池运行两周,或者如果搭配廉价的太阳能电池板则可以无限期运行。根据2018年IEC/IEEE 60255-118-1 PMU标准开发的测试台验证了该PMU的精度。鉴于其低功耗,所提出的设计有望加速PMU在现代配电网中的采用。

英文摘要:

Phasor measurement units (PMUs) provide a high-resolution view of the power system at the locations where they are placed. As such, it is desirable to place them in bulk in low voltage distribution circuits. However, the power consumption of a PMU/micro-PMU is in the order of Watts (W) that results in them requiring an external power supply, which in turn increases the overall cost. This work details the hardware design of a PMU capable of measuring and reporting voltage and current phasors for a single-phase system at an average power consumption of only 30.8 mW -- one to two orders of magnitude lower than existing academic and commercial PMUs. This enables the proposed PMU to run for two weeks using an 11-Wh battery or indefinitely if paired with an inexpensive solar panel. A test-bench developed in accordance with the 2018 IEC/IEEE 60255-118-1 PMU Standard confirms the accuracy of this PMU. Given its low power consumption, the proposed design is expected to accelerate adoption of PMUs in modern distribution grids.
