This proposal explores new concepts for the damage assessment, control, and restoration of the electric power grid following catastrophic disturbances. These disturbances would include:1. Natural disasters like earthquakes, tornadoes, ice storms, wind storms, and large electrical impacts like short circuits, and failure of major components.2. Man-made disasters, such as terrorist attacks, and human errors.The damage assessment consists of determining the severity based on the following criteria:a) Degree of damage, b) Degree of danger, and c) Extent of hazard. This type of analysis will require input from a well-established information and sensing system. The complexity of the problem is further increased because of the large geographical expanse of the Electric Power Transportation system. The use of a wide array of communication technologies including GPS, Microwave Networks, Internet, low earth orbit satellites, and other communication networks will be examined as a part of the information. Infrastructure.Issues related to the scheduling and processing of real time information will also be carefully examined. Key requirements for the computing and communication infracture to support real time supervisory control and data acquisition of large electric power grids are identified. Information and computing architectures to meet these requirements will be proposed.Various control strategies to prevent and minimize the extent of the dislocation of the electric network will be compared. Concepts of graceful degradation as applied to the electric power grid will be proposed. This aspect of the work would also involve corrective strategies to facilitate fast restoration. Newer configurations for the electric power distribution networks and their control and protection equipment so that the network responds to emergencies in a more controlled manner will also be explored.The final step in the investigation will deal with approaches for the restoration of the system following catastrophic disturbances. This is one of the least analyzed aspects of large power grids. It is a highly complex undertaking and involves several issues that relate to automatic restoration as will as manual switching that involves a variety of manpower issues.It is important to note that the power delivery network is overlayed with several hierarchical information and control networks that provide various functions dealing with supervisory control data acquisition, and transaction information in the new deregulated electric utility environment. The roles of each network layer will also be carefully identified.

该提案探讨了灾难性干扰后电力电网的损伤评估，控制和恢复的新概念。这些干扰包括：1。天然灾害，例如地震，龙卷风，冰风暴，风暴和巨大的电气影响，例如短路和主要组成部分的故障。2。人为灾难，例如恐怖袭击和人类错误。损害评估包括基于以下标准确定严重程度：a）损害程度，b）危险程度和c）危险程度。这种类型的分析将需要从公认的信息和传感系统中输入。由于电力运输系统的地理位置庞大，问题的复杂性进一步增加了。将使用广泛的通信技术，包括GPS，微波网络，Internet，低地球轨道卫星和其他通信网络，作为信息的一部分。基础架构。与实时信息的调度和处理有关的发行也将仔细检查。确定了计算和通信违规行为的关键要求，以支持实时监督控制和大型电力网格的数据采集。将提出信息和计算体系结构以满足这些要求。将比较预防和最大程度地降低电网位错程度的各种控制策略。将提出适用于电力网格的优美退化的概念。这项工作的这一方面还将涉及纠正策略，以促进快速修复。电力配电网络及其控制和保护设备的较新配置也将以更控制的方式响应紧急情况。调查的最后一步将处理灾难性干扰后恢复系统的方法。这是大型电网的分析最少的方面之一。这是一项高度复杂的事业，涉及几个与自动恢复有关的问题，就像手动切换一样，涉及各种人力问题。重要的是要注意，电力输送网络覆盖了几个层次信息和控制网络，这些层次信息和控制网络提供了各种功能，这些功能与主管介绍数据采集以及新的脱离电动电动电动式电源环境中的交易信息有关。每个网络层的作用也将仔细识别。
