现代电力生产和输送系统是我们现代工业化社会的关键能源。随着电力负载变得更加关键和苛刻，包括复杂的工业流程和数据仓库，对安全、质量、可靠性和可用性的期望也在增加。由于发电和输电的扩展，包括将分布式发电集成到配电系统中，满足这些要求变得更加困难。为了满足人们的期望，正在不断开发新的有效、可靠和快速反应的故障监测和检测系统。该提案涉及基于先进的多参数分析和检测方案的智能监测和保护装置的开发。提出的智能方法除其他先进工具外，还使用数据挖掘方法从关键指数的大数据集中提取信息，这些大数据集是通过对网络模拟产生的大量事件分析进行离线筛选而获得的。该方法适用于配电系统和输电系统中的保护装置。在配电系统中，该方法用于检测分布式电源孤岛。它结合了许多系统参数，以检测许多可能的网络拓扑、分布式发电渗透级别和运行条件的孤岛。在输电系统中，该方法用于监测输电系统的状况，特别是在压力条件下，并提醒系统操作员可能导致系统崩溃的违规行为。新的保护装置预计将提高故障监测和检测的有效性，从而改善输电和配电系统运行的关键方面。

Modern electrical power generation and delivery systems are a key source of energy for our modern industrialized society. Expectations related to security, quality, reliability and availability are increasing as electrical loads are becoming more critical and demanding, including complex industrial processes and data warehouses. Meeting these requirements is made more difficult by generation and transmission expansion, including the integration of distributed generation into electrical distribution systems. To meet expectations, new effective, reliable and fast acting fault monitoring and detection systems are constantly being developed. This proposal deals with the development of intelligent monitoring and protection devices based on advanced multi-parameter analysis and detection schemes. The proposed intelligent approach uses, among other advanced tools, the data-mining methodology to extract information from the large data sets of critical indices obtained by off line screening of massive event analyses produced by network simulations. This methodology is applied in protection devices in both the distribution and transmission systems. In distribution systems, the approach is used to detect distributed generation islanding. It combines a number of system parameters in order to detect islanding for many possible network topologies, distributed generation penetration levels, and operating conditions. In transmission systems, the approach is applied to monitor the condition of a transmission system, particularly under conditions of stress, and alert the system operator of violations that may cause system collapse. The new protection devices are expected to increase the effectiveness fault monitoring and detection and therefore improve critical aspects of the operation of transmission and distribution systems.
