Design of Power Lines Monitoring System with C/S Structure

在电力行业高速发展、电网规模日益扩大的今天,电力线路信息的有效监控能够便于掌握电网的实时运行状况,保障电力系统的安全稳定运行,发生故障时也能尽快地完成故障分析与分类。为此,采用C++ Builder语言进行系统界面设计,简要设计完成了一种电力线路的信息监控系统;运用数据库技术将电力线路数据信息进行分类存储,使得能够快速有效地显示实时的线路数据,方便查询历史信息;采用基于暂态量的故障选相算法实现了线路故障的分类,便于工作人员分析故障原因、查找故障点。实验结果表明,该系统能够实现线路信息的实时显示和历史数据的查询,达到实时监控的目的,减轻了工作人员的工作强度,提高了线路信息管理的效率,同时也有效提高了电力系统的自动化水平。

With the rapid development of the power industry and the increasing scale of the power grid,it is convenient for effective moll- toting of information of power lines to grasp the real-time operation of the power grid,guarantee the safe and stable operation of the pow- er system and complete the fault analysis and classification as soon as possible when a fault occurs. Tberefore,the language of C＋＋ Build- er is adopted to design system interface, and an information monitoring system of the power lines is designed and implemented briefly. The database technology is employed to classify and store the data of power lines, which makes that the real-time data can be displayed quickly and effectively and the historical information can be queried conveniently. The fault phase selection algorithm based on transient is adopted to classify the line faults so that the staff can analyze the cause of fault and find the point of faults. The experimental results in- dicate that the real-time display of the line information and the query of historical data could be realized to achieve the goal of real-time molltoring, reduction of workload of staff,improvement of the management efficiency of line information and raising the level of automa- tion effectively.
