摘要
数学形态学在信号处理中具有较强的滤波和抗干扰能力,探讨了其在牵引供电系统中的应用。介绍了数学形态学的基本概念及其在电力系统各个领域的研究现状,并针对目前电气化铁路牵引供电系统中在故障测距、电能质量分析等方面存在的信号处理的精度和适用范围具有局限性等问题,讨论了数学形态学在电气化铁路牵引供电系统中的应用方向。提出基于数学形态学的牵引网故障测距、牵引网电能质量分析和故障识别方案,以提高电气化铁路电能质量,保证牵引供电系统的稳定性。
Mathematical morphology is provided with characteristics of strong filtering and antijamming capacities in information processing. This paper discusses application of mathematical morphology in traction power system and introduces its basic concept and study status quo in various fields of electric power system. Aiming at problems of boundedness of precision for information processing and range of application in aspects of fault location and analysis on power quality, it discusses ap- plication direction of mathematical morphology in traction power system of electric railway. In addition, it proposes schemes for traction network fault location, power quality analysis and fault recognition based on mathematical morphology in order to improve power quality of electric railway and ensure stability of traction system.
