Following a series of serious power blackout incidents in 2003, policy makers in the European Union and the USA have highlighted (i) the need for improved a.c. transmission grid infrastructure and advanced control technologies to enhance stability and security in an increasingly complex operating environment, and (ii) the importance of emerging measurement-based technology towards achieving such enhanced operation. The concept of this proposal is a system for transmission security assessment using the emerging measurement technologies of high-bandwidth SCADA systems and the wide area measurement systems (WAMS) which are based on time-synchronized phasor measurement units. It will lead to better situational awareness and initiate control action for optimal operation closer to loading constraints while reducing the risks of blackouts.Very recent developments in measurement-based analyses being used in oil, gas and chemicals plants point the way towards much better signal analysis applications for the emerging measurement-based technologies in power transmission systems. The measurement-based system proposed in this project would greatly extend the basic methods that are used at present and will lead to localization and real-time diagnosis of the root causes of threats to transmission system security and actions to control the situation. It offers a more predictive, responsive and accurate approach than the transmission system models which are currently used, while the signal analysis methods now being used in experimental WAMS and high-bandwidth SCADA systems would advance from their current narrow emphasis on Fourier methods adopted from the aerospace industries. For instance the project would develop signal analysis methods for use when transient events excite system non-linearities. This will provide a much more accurate indication of the true situation during developing emergencies.This project is timely and is giving an immediate response to research needs identified in the Spring of 2006 in policy documents from the EU and US. Success in shifting the emphasis from model-based to measurement-based assessments will benefit the wider field of a.c. transmission stability and security as well as creating an a.c. transmission security enhancement system in a fit state for technology transfer. A first-rate team has been assembled for the task, namely Imperial College London (expertise in robust damping control of inter-area oscillations) and UCL (expertise in measurement-based analysis for process systems), National Grid (provision of high-bandwidth SCADA data, system specification and testing, a UK industrial viewpoint) and ABB (provision of PMU data, system development, the industrial viewpoint from continental Europe). The university researchers will do part of the work on secondment with National Grid and ABB. It is quite realistic to expect success from this team.

在2003年发生了一系列严重的停电事件后，欧盟和美国的政策制定者强调了(I)改善交流电源的必要性。(I)输电电网基础设施和先进控制技术在日益复杂的运行环境中增强稳定性和安全性的重要性；(Ii)新兴的基于测量的技术对实现这种增强运行的重要性。该方案的概念是使用基于时间同步相量测量单元的高带宽SCADA系统和广域测量系统(WAMS)的新兴测量技术进行传输安全评估的系统。它将导致更好的情景感知和启动控制行动，以实现更接近负荷约束的最佳运行，同时减少停电风险。石油、天然气和化工厂中使用的基于测量的分析的最新发展为电力传输系统中新兴的基于测量的技术提供了更好的信号分析应用。本项目提出的基于测量的系统将极大地扩展目前使用的基本方法，并将导致对威胁传输系统安全的根本原因进行本地化和实时诊断，并采取措施控制局势。它提供了一种比目前使用的传输系统模型更具预测性、响应性和准确性的方法，而目前用于实验性WAMS和高带宽SCADA系统的信号分析方法将从目前对航空航天行业采用的傅立叶方法的狭隘强调中进步。例如，该项目将开发信号分析方法，以便在瞬时事件激发系统非线性时使用。这将更准确地指示发展紧急情况的真实情况。该项目是及时的，并立即对欧盟和美国的政策文件中确定的2006年春季的研究需求做出回应。如果成功地将重点从基于模型的评估转移到基于测量的评估，将有利于更广泛的交流领域。传输稳定性和安全性，以及创建交流。传输安全增强系统处于适合技术转让的状态。为这项任务组建了一流的团队，即伦敦帝国理工学院(Imperial College London)(在区域间振荡的强健减振控制方面的专业知识)和UCL(过程系统基于测量的分析方面的专业知识)，国家电网(提供高带宽SCADA数据、系统规范和测试，英国工业观点)和ABB(提供PMU数据、系统开发、欧洲大陆的工业观点)。大学研究人员将与国家电网和ABB进行部分借调工作。期待这支球队取得成功是非常现实的。
