本文探究能否从PMU同步相量数据中直接提取间谐波以定位电力系统振荡源，结果表明特定振荡现象下可实现，还开发了基于云的PMU源定位软件工具。
AI 中文摘要
近期研究表明，振荡相量源于间谐波引发的拍波，这一发现催生了基于间谐波的振荡源定位方法，但该方法所需的波形数据远不如PMU同步相量数据易得。本文探究能否直接从相量数据中提取间谐波以用于类似应用，结果显示，针对特定振荡现象，相量数据可支持间谐波提取与振荡源定位；敏感性研究明确了相关要求，且已开发出一款基于云的软件工具用于PMU驱动的源定位。
英文摘要
Recent studies have shown that oscillating phasors arise from beating waves caused by interharmonics. This finding has led to an interharmonic-based oscillation source-location method. But waveform data needed for the method are less available than PMU synchrophasor data. This paper investigates whether interharmonics can be extracted directly from phasor data for similar applications. The results show that, for certain oscillation phenomena, phasor data can support interharmonic extraction and oscillation source location. Sensitivity studies have identified the requirements, and a cloud-based software tool is developed for PMU-based source location.
