研究目的与方法：本研究的目的是为相量测量单元的操作和应用开发有效的，高效的，实用的算法。办法是：1）开发新一代相量测量单元，采用新的信号建模和处理方法，实现静态和动态分析; 2）通过探索不良数据识别和去除方法，深入了解不良相量数据处理; 3）建立一个理论框架，使用统计推断和压缩感知显式处理不良数据; 4）从仿真中确定我们的方法在哪些方面带来了改进的态势感知，并用现场数据进行验证。智力上的优点：相量测量单元的当前技术水平与其设想的能力之间的差距要求超越今天的先进技术？的行业标准。这项研究计划将有助于这一奋进，开发新的信号处理技术量身定制的相量测量单元及其应用。算法的成功开发也将对信号处理中的同步和异常检测的一些基本问题产生影响。更广泛的影响：在美国，电力中断造成的损失每年高达1350亿美元。一个主要原因是对形势的认识不足。随着提议的进步，下一代相量测量单元将随时随地提供真正准确的电网状况。除了将研究问题纳入我们的课程之外，还将特别努力通过工业实习来丰富研究生培训，并招募和留住妇女和贫困学生。

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.
