【摘要】：随着人们生活水平的提高,人们对电力能源的依赖也越来越高,相对于电能质量停电时间的要求也越来越高。目前国内外都在积极规划、建设智能电网,其核心是实现电网的信息化、数字化、自动化和互动化。配网故障定位是实现智能电网的第一步。通过先进的传感和测量技术、先进的设备技术、先进的控制方法以及先进的决策支持系统技术,建立实时电网管理,使发电、输电、配电、用电四方互动互通,实现配网的故障定位。系统主动监管电力故障并迅速进行反应,实现更智慧的电力供给与配送,实现电网的可靠、安全、经济、高效、环境友好和使用安全的目标。基于以上研究背景,针对现有配网定位系统定位精确、漏报、误报严重,提出了一种配网故障定位算法。并以此算法为核心,搭建了一套配网故障监测系统。该系统在云南省,昆明、大理、临沧、版纳等地区试运行。文章研究内容如下。(1)设计新型拓扑结构描述的信息模型、包括基于该模型的排序算法,遍历算法等。(2)根据上述信息模型设计,故障事件分类算法,针对通信终端上报信息进行分类、整理、判定,最终尽可能的还原出发生在线路上的故障事件。(3)设计故障定位算法,对故障事件的故障位置进行故障定位,并通过多种途径展现给用户。(4)利用遗传算法对故障定位算法进行。
[Abstract]:With the improvement of people's living standard, people depend more and more on the power energy, and the demand of power quality blackout time is higher and higher. At present, smart grid is actively planned and built at home and abroad, the core of which is to realize the informatization, digitization, automation and interaction of power grid. Distribution network fault location is the first step to realize smart grid. Through advanced sensing and measurement technology, advanced equipment technology, advanced control method and advanced decision support system technology, the establishment of real-time power grid management, so that generation, transmission, distribution, electricity quadripartite interaction, The fault location of distribution network is realized. The system actively supervises power failures and responds quickly to achieve more intelligent power supply and distribution, and to achieve the goal of reliable, safe, economical, efficient, environment-friendly and safe use of the power grid. Based on the above research background, a fault location algorithm for distribution network is proposed in view of the accurate location, false positives and false positives of the existing distribution network location system. Based on this algorithm, a fault monitoring system of distribution network is built. The system in Yunnan, Kunming, Dali, Lincang, Banna and other regions trial operation. The main contents of this paper are as follows: (1) designing a new information model for topology description, including sorting algorithm based on this model, traversal algorithm and so on. (2) according to the above information model, the fault event classification algorithm is designed. The information reported by the communication terminal is classified, sorted, judged, and finally the fault events occurring on the line are restored as much as possible. (3) the fault location algorithm is designed to locate the fault location of the fault events. And through a variety of ways to show to the user. (4) genetic algorithm for fault location algorithm.
