Advancing Phasor Measurement Unit (PMU) Technology

研究目标与方法：本研究的目的是为相量测量单元的操作和应用开发有效、高效和实用的算法。方法是：1)开发具有新颖信号建模和处理的下一代相量测量单元，以实现静态和动态分析；2)深入了解坏相量数据处理，探索坏相量数据识别和去除方法；3)建立理论框架，利用统计推理和压缩感知明确处理不良数据；4)从模拟中识别出我们的方法在哪些方面提高了态势感知能力，并通过现场数据进行验证。知识价值：相量测量单元的当前技术状态与其设想的能力之间的差距要求超越今天的先进技术？美国行业标准。本研究计划将通过开发适合相量测量单元及其应用的新型信号处理技术来促进这一努力。这些算法的成功开发也将对信号处理中的同步和异常检测等一些基本问题产生影响。更广泛的影响：在美国，电力中断每年造成的损失高达1350亿美元。一个主要原因是对形势的认识不足。随着提出的进步，下一代相量测量单元将提供一个真正准确的网格条件的图片，随时随地。除了将研究问题纳入我们的课程外，我们将特别努力以工业实习丰富研究生培训，并招募和留住女性和贫困学生。

Research Objectives and Approaches:The objective of this research is to develop effective, efficient, and practical algorithms for phasor measurement unit operation and application. The approach is to: 1) develop the next generation phasor measurement unit with novel signal modeling and processing to enable both static and dynamic analysis; 2) gain a thorough understanding of bad phasor data processing by exploring methods of bad data identification and removal; 3) establish a theoretical framework to explicitly deal with bad data using statistical inference and compressive sensing; and 4) identify from simulation where our methods bring improved situational awareness, and verify with field data.Intellectual Merit:The gap between the current state of the art in phasor measurement units and their envisioned capability calls for advanced technology beyond today?s industry standards. This research proposal will contribute to this endeavor by developing novel signal processing techniques tailored for thephasor measurement unit and its applications. Successful development of the algorithms will also have impact on a number of fundamental problems of synchronization and anomaly detection in signal processing.Broader Impacts:In the U.S., power interruptions cost up to $135 billion each year. A main cause is inadequate situational awareness. With the proposed advancement, the next generation phasor measurement units will provide a picture of grid conditions that is truly accurate, anytime, and everywhere. Besides integrating research issues into our curriculum, special efforts will be made to enrich graduate student training with industrial internships, and to recruit and retain women and underprivileged students.
