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, effective monitoring of power line information can help to grasp the real-time operation status of the power grid and ensure the safe and stable operation of the power system. Fault analysis and classification can also be completed as soon as possible in the event of a fault. Therefore, using C ++ Builder language to design the system interface, a kind of information monitoring system of power line has been designed and designed briefly. Using database technology to classify and store the power line data information, it can display real-time line data quickly and efficiently, Historical information; Fault classification algorithm based on transient quantity is adopted to realize the classification of line faults, which is convenient for staff to analyze the cause of faults and locate the fault point. The experimental results show that the system can realize the real-time display of line information and query of historical data to achieve the purpose of real-time monitoring, reduce the work intensity of staff and improve the efficiency of line information management, and also effectively improve the automation of power system Level.
