摘要

本文从实际事件分析出发,着重研究响应暂态故障条件的网络参数,提出了一种快速、可靠的高压输电线路保护控制结构。在架空电力线路中,大约80%的已登记故障具有暂态特征。因此,暂态故障的管理非常重要,因为这直接影响到能源分配过程,并对供应给用户的能源质量有很大影响。建立适用性广泛的数学模型,通过对实际生活事件中记录的数据进行分析,可以准确地表示110千伏线路上暂态故障的传播,从而对实际故障进行清晰的及时表示。使用这些数学模型可以减少暂态故障的检测时间,确保在减少停电程度方面的好处,从而缩短恢复时间。本文提出的暂态故障检测和线路保护触发控制结构的运行算法,在暂态故障发生时提高了距离保护反应,安全克服了网络运行中的关键时刻,推荐本文提出的解决方案可供实际实施。DOI: 10.61416 / ceai.v25i2.8603

High Voltage Power Line Transient Fault Analyzing and Modelling
The research presents a protective control structure for fast and reliable high voltage power line protection that focuses on network parameters that respond to transient faults conditions, starting from the analysis of a real event. In case of overhead power lines, approximately 80% of the total registered faults have a transient character. Therefore, the management of transient faults is important because this has a direct consequence on the energy distribution process and has a large influence on the quality of energy supplied to consumers. The development of mathematical models of wide applicability, to accurately represent the propagation of a transient fault on the 110 kV lines is possible through data analysis recorded during real life events, which constitute a clear representation in time of an actual fault. The use of these mathematical models made it possible to reduce the detection time of transient faults, ensuring benefits in terms of reducing the extent of power outages, which leads to shorter recovery times. The proposed operating algorithm of the developed control structure for transient fault detection and line protection triggering allows the improvement of distance protection reaction in the event of a transient fault, to safely overcome critical moments in network operation, aspects that recommend the proposed solution for practical implementation.

期刊介绍: The Journal is promoting theoretical and practical results in a large research field of Control Engineering and Technical Informatics. It has been published since 1999 under the Romanian Society of Control Engineering and Technical Informatics coordination, in its quality of IFAC Romanian National Member Organization and it appears quarterly. Each issue has up to 12 papers from various areas such as control theory, computer engineering, and applied informatics. Basic topics included in our Journal since 1999 have been time-invariant control systems, including robustness, stability, time delay aspects; advanced control strategies, including adaptive, predictive, nonlinear, intelligent, multi-model techniques; intelligent control techniques such as fuzzy, neural, genetic algorithms, and expert systems; and discrete event and hybrid systems, networks and embedded systems. Application areas covered have been environmental engineering, power systems, biomedical engineering, industrial and mobile robotics, and manufacturing.
