【摘要】：配电网故障定位系统是一种用于配电网的故障定位系统。它通过监测终端对配电网进行监测,当配电网发生故障后,故障信息会被发送给监测主站。监测主站收到故障信息后对配电网的故障信息进行整体分析,得出故障区段或故障点,并将故障区段或故障点的相关地理信息告知运行人员和维修人员。很明显,根据此地理信息,维修人员可更快地找到故障区域,从而缩短了故障恢复时间。因此,配电网故障定位系统可以有效地提高配电网的供电可靠性。本文所研究的配电网故障定位系统是一种区段故障定位系统,它采用GPRS作为主要通信网络,其监测终端是故障指示器。整个系统由数据中心、DTU和故障指示器组成。其中,故障指示器被安装在线路上,用于监测线路状态。故障指示器可以通过无线射频器与DTU进行交互通信,DTU可以通过GPRS网与数据中心进行交互通信。因此,故障指示器可以间接与数据中心进行交互通信。数据中心上安装有故障分析软件,它可以通过分析故障信息得出故障区段。本文首先阐述了配电网故障定位系统的研究背景、意义及现状。其次,对基于GPRS的配电网故障定位系统的组网原理、组网方案及方案安全性进行了介绍,并根据本故障定位系统的要求选定了最佳组网方案。然后,着重研究了故障分析软件的开发思想和故障定位算法。在此部分,本文先分析了故障分析软件的结构,然后根据此结构特点分别对组成软件的各个子系统进行了分析。在每个子系统的研究分析过程中,本文大多是先介绍某子系统的功能,然后再根据该子系统的特点侧重研究、分析和讲解其核心内容,为讲解清楚某些子系统的实现过程,使用了一定量的源码。最后对全文进行了总结和展望。
[Abstract]:Distribution network fault location system is a fault location system used in distribution network. It monitors the distribution network through the monitoring terminal. When the distribution network fails, the fault information will be sent to the main monitoring station. After the main station receives the fault information, the fault information of the distribution network is analyzed as a whole, and the fault section or fault point is obtained, and the relevant geographic information of the fault section or fault point is informed to the operator and the maintenance personnel. Obviously, based on this geographic information, the maintainer can find the fault area more quickly, thus reducing the recovery time. Therefore, the distribution network fault location system can effectively improve the distribution network power supply reliability. The fault location system of distribution network studied in this paper is a section fault location system. It uses GPRS as the main communication network and its monitoring terminal is the fault indicator. The whole system consists of data center DTU and fault indicator. The fault indicator is installed on the line to monitor the line state. The fault indicator can communicate interactively with DTU via radio frequency device. DTU can communicate with data center through GPRS network. Therefore, the fault indicator can communicate indirectly with the data center. Fault analysis software is installed in the data center, which can get fault section by analyzing fault information. In this paper, the research background, significance and present situation of distribution network fault location system are introduced. Secondly, the principle, scheme and security of fault location system of distribution network based on GPRS are introduced, and the best scheme is selected according to the requirements of the fault location system. Then, the development idea and fault location algorithm of fault analysis software are studied. In this part, the structure of the fault analysis software is analyzed firstly, and then the subsystems of the software are analyzed according to the characteristics of the structure. In the research and analysis process of each subsystem, this paper mainly introduces the function of a subsystem, then according to the characteristics of the subsystem, analyzes and explains its core content, in order to explain the realization process of some subsystems. Used a certain amount of source code. Finally, the full text is summarized and prospected.
