【摘要】：配電網(wǎng)故障定位系統(tǒng)是一種用于配電網(wǎng)的故障定位系統(tǒng)。它通過(guò)監(jiān)測(cè)終端對(duì)配電網(wǎng)進(jìn)行監(jiān)測(cè),當(dāng)配電網(wǎng)發(fā)生故障后,故障信息會(huì)被發(fā)送給監(jiān)測(cè)主站。監(jiān)測(cè)主站收到故障信息后對(duì)配電網(wǎng)的故障信息進(jìn)行整體分析,得出故障區(qū)段或故障點(diǎn),并將故障區(qū)段或故障點(diǎn)的相關(guān)地理信息告知運(yùn)行人員和維修人員。很明顯,根據(jù)此地理信息,維修人員可更快地找到故障區(qū)域,從而縮短了故障恢復(fù)時(shí)間。因此,配電網(wǎng)故障定位系統(tǒng)可以有效地提高配電網(wǎng)的供電可靠性。 本文所研究的配電網(wǎng)故障定位系統(tǒng)是一種區(qū)段故障定位系統(tǒng),它采用GPRS作為主要通信網(wǎng)絡(luò),其監(jiān)測(cè)終端是故障指示器。整個(gè)系統(tǒng)由數(shù)據(jù)中心、DTU和故障指示器組成。其中,故障指示器被安裝在線路上,用于監(jiān)測(cè)線路狀態(tài)。故障指示器可以通過(guò)無(wú)線射頻器與DTU進(jìn)行交互通信,DTU可以通過(guò)GPRS網(wǎng)與數(shù)據(jù)中心進(jìn)行交互通信。因此,故障指示器可以間接與數(shù)據(jù)中心進(jìn)行交互通信。數(shù)據(jù)中心上安裝有故障分析軟件,它可以通過(guò)分析故障信息得出故障區(qū)段。 本文首先闡述了配電網(wǎng)故障定位系統(tǒng)的研究背景、意義及現(xiàn)狀。其次,對(duì)基于GPRS的配電網(wǎng)故障定位系統(tǒng)的組網(wǎng)原理、組網(wǎng)方案及方案安全性進(jìn)行了介紹,并根據(jù)本故障定位系統(tǒng)的要求選定了最佳組網(wǎng)方案。然后,著重研究了故障分析軟件的開(kāi)發(fā)思想和故障定位算法。在此部分,本文先分析了故障分析軟件的結(jié)構(gòu),然后根據(jù)此結(jié)構(gòu)特點(diǎn)分別對(duì)組成軟件的各個(gè)子系統(tǒng)進(jìn)行了分析。在每個(gè)子系統(tǒng)的研究分析過(guò)程中,本文大多是先介紹某子系統(tǒng)的功能,然后再根據(jù)該子系統(tǒng)的特點(diǎn)側(cè)重研究、分析和講解其核心內(nèi)容,為講解清楚某些子系統(tǒng)的實(shí)現(xiàn)過(guò)程,使用了一定量的源碼。最后對(duì)全文進(jìn)行了總結(jié)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.
