【摘要】：随着现代信息处理技术等综合智能系统近年来的快速发展,使得输电线路设备在线监测成为可能,监测雷击活动,从而准确定位故障点位,也变成了一种可行性操作途径。雷击导致的跳闸障碍往往造成巨大的经济损失和不良的社会影响。既给电力部门造成了直接的经济损失,也给居民用电及工农业生产带来不良影响。一旦线路遭受雷击跳闸,如何尽快的查找到故障点位,快速进行处置,及时恢复送电,降低损失,成为一个重要的课题。相关资料统计显示超过80%的线路故障是由单相短路接地引起的。概率紧随其后的是两相短路接地故障,其所占的比例为2%到3%之间,而三相短路接地故障发生的概率仅为1%到3%左右,在很长一段时间内都无法通过技术手段去详细的定位雷击故障的位置。我国的电网发展非常的迅速,电网中的线路和其他元器件设备的检查和更新任务会越来越繁重。所以一个高可靠性的电网必将是线路出现问题的概率低,并且一旦出现事故,该电网负责公司能够立马准确定位故障来源,并且迅速消除故障,恢复电网供电功能。雷电数据系统的功能是给客户提供及时的雷电数据、线路故障的搜查、范围和回路各种数据的统计、回路的编辑等各种功能。最终客户是利用雷电网络来获取雷电信息的。雷电网站使用信息技术来得到客户的需求,再把客户的需求传送到雷电服务系统。雷电服务系统将雷电信息从信息库中提取,再结合有关的地理数据,变成客户需求的格式,利用IIS变成网页的方式传递给最终客户。本文搭建的电网雷电监测系统主要是对电力公司的电网进行实时监测,期望在该系统的积极作用下,能够准确实时地记录下该地区雷电对电网的影响情况,如雷打造成事故的概率,定位线路故障源等问题。同时也根据该处的实际情况制定出一系列的应对措施,尽力减小因雷电因素造成电网故障的概率,提高该处电网的可靠性和高维修性。本系统的设计与实现能够很好的实现对输电线路雷击故障的定位,为在电网中排除雷击故障提供了全方位的支持,能够使电网雷击故障的管理走向信息化。
[Abstract]:With the rapid development of integrated intelligent systems such as modern information processing technology in recent years, it is possible for on-line monitoring of transmission line equipment, monitoring lightning strike activities, so as to accurately locate fault points. It has also become a feasible way of operation. Tripping barriers caused by lightning often cause huge economic losses and adverse social impact, which have caused direct economic losses to the power sector. Once the line is struck and tripped by lightning, how to find the fault point as soon as possible, to deal with it quickly, to restore the power supply in time, and to reduce the loss. It has become an important subject. Statistics show that more than 80% of the line faults are caused by single-phase short-circuit grounding, followed by the probability of two-phase short-circuit grounding fault. Its proportion is between 2% and 3%, while the probability of three-phase short-circuit grounding fault is only about 1% to 3%. In a very long period of time, it is impossible to locate the location of lightning fault in detail by technical means. The development of power grid in China is very rapid. The task of checking and updating the line and other components in the power network will be more and more heavy. Therefore, a high reliability power network will have a low probability of line problems, and once there is an accident. The power grid is responsible for the company to locate the source of the fault immediately and quickly eliminate the fault and restore the power supply function of the grid. The function of the lightning data system is to provide customers with timely lightning data and line fault search. Range and circuit of various data statistics, circuit editing and other functions. The ultimate customer is to use the lightning network to obtain lightning information. Lightning website uses information technology to obtain customer needs. Then the customer's needs are transmitted to the lightning service system, which extracts the lightning information from the information base, and then combines the related geographical data, and becomes the format of the customer's demand. The lightning monitoring system built in this paper is mainly used to monitor the power grid in real time, in the hope of the active role of the system. It can record the impact of lightning on the power grid accurately and real-time, such as the probability of the lightning accident, locating the fault source of line, etc. At the same time, a series of countermeasures are worked out according to the actual situation of the area. Try to reduce the probability of power network failure caused by lightning factors, improve the reliability and high maintainability of the power system. The design and implementation of the system can achieve a good location of transmission line lightning fault. It provides omni-directional support for the elimination of lightning strike fault in power grid, and can make the management of lightning strike fault in power grid information.
