Synchrophasor measurement

同步相量测量是电力系统研究领域的一个新兴领域。虽然这件事 技术相对较新，已有研究表明，从电能中提取同步相量测量 电网，用于电力系统监测和控制应用，提高了性能和 电网的可靠性。 同步相量将交流波形的相量表示与精确、通用的时间戳相结合。 与同步相量测量相关的主要量有四个：(I)相量大小；(Ii)相量 角度、(Iii)基频和(Iv)频率变化率(ROCOF)。提取的仪器 这四个测量并将结果传输到中央数据采集点称为PMU(相量 计量单位)。 该项目的目标是扩大最近完成的一项活动赠款的工作，并制定一项 具有两个互补功能的全功能测量装置：(A)具有以下功能的相量测量装置 快速瞬变响应时间和(B)高分辨率数字波形记录器。 数据存档将有助于同步相位仪的准确性验证，也将支持新兴领域 电能质量数据分析公司。最终目标是展示产品概念的可行性，然后才能 发展迅速，并推向市场。这将是第一个在功率测量中使用的装置 工业。

Synchrophasor measurements are a new emerging field in the area of power system research. While this technology is relatively new, it has been shown that extracting synchrophasor measurements from the power grid, for use in power system monitoring and control applications, results in improved performance and reliability of the power grid. Synchrophasors combine the phasor representation of AC waveforms with a precise, universal time stamp. There are four main quantities associated with synchrophasor measurements: (i) phasor magnitude, (ii) phasor angle, (iii) fundamental frequency and (iv) rate of change of frequency (ROCOF). Instruments that extract these four measurements and transmit the results to a central data collection point are called PMUs (Phasor Measurement Units). The goal of this project is to expand the work on a recently completed ENGAGE grant and develop a fully-functional measurement device with two complementary functions: (a) a phasor measurement unit with fast transient response times and (b) a high resolution digital waveform recorder. Archival of data will be useful for synchrophasor accuracy verification and also will support the emerging field of Power Quality Data Analytics. The end goal is to show the feasibility of a product concept that could then be developed quickly and brought to market. This device would be the first of its kind in the power measurement industry.
