基于LabVIEW的电力系统过电压监测研究
|
摘要
电力系统过电压是和绝缘配合密切相关的一门学科,电气设备遭受过电压情况可以反映绝缘配合是否合理。电力设备在线监测技术是近年来发展十分迅速,而又跨越多门学科的新兴技术,已在电力系统中得到广泛应用。但对于电力系统过电压的监测,现有的故障录波器由于频率响应不够,很难监测到很多过电压发生的真实情况。因此,需要研发高性能、自动化的在线监测设备,以实现过电压发生时,能完整准确地记录过电压的实际变化过程,并保存过电压的波形和数据,为了解事故发生前后过电压的情况,和发生过程中对电网电压的影响提供准确资料,为科研及运行人员分析事故原因,为电网安全运行提供可靠依据。
本文以现场实测的电力系统过电压数据为研究对象,开展了基于LabVIEW的电力系统过电压数据分析系统的研究和开发工作。首先论述了电力系统过电压分析的重要意义,详细分析了国内外过电压分析的研究现状及发展趋势。接着叙述电力系统过电压的主要种类,即分为外部过电压和内部过电压两种类型,分别阐述各自的特点,即在正常绝缘配合下的发生各类过电压波形特点,包括幅值和持续时间等。作者以四川电力试验研究院研制的“TR2000-B型暂态过电压监测及记录系统”的记录获得分析的数据,在LabVIEW上实现应有的分析功能进行分析,作者对现场收集到过电压数据中一些典型的、频繁出现的过电压波形进行了分析,判断过电压的类型和产生的原因,这对于研究判断电气设备的绝缘强度、检修周期、设备改进和系统改造、过电压对电力系统的影响方式和程度以及过电压的防范等都具有重要的指导意义。
Power system over-voltage is a subject closely in correlation with equipment insulation. Over-voltage condition suffering on equipments can indirectly inflect whether insulation cooperation is reasonable. Power equipment on-line monitoring technology recently develops so rapidly, and it is a new technology that spans multi-disciplinary and is applied extensively in the power system. However most of oscilloscopes fail to monitor over-voltage waveform for their frequency despondence so that they can not been used to get real condition. So it's necessary to develop highly performing and automation equipment to implement recording completely and exactly real changing process of voltage when defaults happen, at the same time, saving waveforms and several parameters in order to know condition at that time and affection to power system which can afford some accurate datum for scientific research and operation personnel to analyze reasons for fault and to afford reliable proof whether power system is safe.
This paper is takes those dates which be got from field engineering as the research object. The analysis system of over-voltage dates from electric power system based on LabVIEW technology are researched and developed also. To begin with, this paper deals with the importance of over-voltage analysis system in electric power system. The existing research status in the world, the developing trends and the application prospects for over-voltage analysis are introduced in details.LabVIEW programming language which is used in the paper is simply introduced. The author prefers "TR2000-B Transient Over-voltage Monitoring and Recording System" developed by Sichuan Power Trial Institute, to obtain analysis data. The author develop a program to analyze this data by LabVIEW .The program can give enough analyses function. At the over of the part, the author quotes some classical and frequent over-voltage waveforms and analysis them. By analysis some classical and frequent over-voltage waveforms, the type and reason of over-voltage can be obtained. The result of over-voltage analysis can have an important influence on the researching and deciding insulate intensity of electric installation ,repair cycle ,equipment improved, over-voltage's effect on power system and preventing of over-voltage.
