报告摘要：

众所周知，一个完整的电力系统是世界上最大、最复杂的系统之一。例如，北美西部电网乃是一个跨越十四个

美国州、两个加拿大省以及部分墨西哥的完全连通系统。因着其涵盖的范围以及其复杂性，这样的系统难以让

人完全理解、建模以及操作。此外，随着可再生能源的增多以及新输电网的有限性，电网如今正变得更为复杂。

一个伴随着美国2009恢复及重投法案而来的一项新技术，是相量测量，该技术可给供电方提供由地球定位系统

（GPS）时间同步的对全局电网的高速测量数据。这种技术已被广泛安装，但却未得到广泛的使用。这些测量

系统被称为广域测量系统，该系统所使用的测量设备为相量测量单元（PMU）。这些海量的实时同步相量数据

被认为是监测、运作以及控制电网、保证其持续可靠、经济运行的非常有潜力的资源。其潜在的影响是很巨大

的，这些数据可帮助提升电网的可靠性以及减少由于电力系统扰动、断电时带来的经济损失。

该测量系统还非常新，至今仍未被充分使用。控制中心面临着巨大的运算任务，包括存储、读取、处理上千个

管道的高速实时同步相量数据以及从这些数据中提取有效的信息来展示给操作员。直到最近，人们才开始致力

于为这些高速数据全力开发相应的应用。在本讲座中，我们将综览怀俄明大学在基于测量的电力系统建模领域

所做的研究， 并且以伪GPS信号攻击的同步相量数据矫正为例做深入讨论。

Title: Measurement-Based Power System Modeling

Abstract

A complete power system is arguably one of the largest and most complicated systems in the world. For example,

the western North Americanpower grid is one totally interconnected system involving 14 western US states, two

Canadian provinces, and a portion of Mexico. Such systems are difficult to fully understand, model, and operate

due to their scope as well as complexity. With increased renewable penetration and a limited amount of new

transmission, the grids are becoming even more complex.

A key new technology that has been widely installed due to the American Recovery and Reinvestment Act of 2009,

but not yet widely utilized, is synchrophasor measurements which provide power utilities GPS time‐synchronized

high‐rate measurement data from the entire grid. These measurement systems are known as Wide‐Area‐

Measurement‐Systems (WAMS) and they extensively use Phasor Measurement Units (PMUs) as the measurement

devices. This vast amount of real-time synchrophasor data is considered the most promising resource to monitor,

operate, and control the grid to ensure its future reliable and economic operation. The potential impact is tremendous

with the possibility of increasing the reliability of the grid and decreasing the economic loss from power system

disturbances and outages. Much of the measurement system is brand new and to date highly underutilized. Control

centers have a computationally challenging task of storing, accessing, processing, and extracting the useful

information to display from up to a thousand channels of high data‐rate real‐time synchrophasors. Only now

is effort being placed on fully developing applications for this high speed data.

In this talk, we will give an overview of the research in measurement-based power system modeling at the University

of Wyoming, with a particular example in the GPS-spoofed synchrophasor data correction.
