【摘要】：作为智能电网建设的关键环节以及电能输送的纽带的输电线路，是电力系统的重要组成部分，一旦发生运行故障，会导致区域电力系统的崩溃，造成严重的电网事故，只有对输电线路本体和周围环境的进行全面在线监测，才能保证线路安全、可靠、稳定运行，因此，，输电线路在线监测的开展建设对于避免电网事故、保障线路安全至关重要。 论文根据国内输电网在线监测的典型工程应用经验，全面探究了智能电网相关技术支持，对输电线路远程在线监测关键技术展开应用研究，以便能够实时监测输电线路本体及周围环境的工况。本文主要包括监测装置选型设计、前端监测装置及主站的供电电源设计、监测数据的传输通信设计等部分，并对重点隐患线路进行现场勘测和相关在线监测装置应用设计，最后，详细分析了系统试点建设后具体应用效果，通过接入该系统，积累了大量线路实际运行数据，输电线路安全管理水平和运行水平得到了显著提高，实现高压重点线路隐患“可控、能控、在控”，这为智能电网的开展及在线监测的不断深入提供重要的实践依据。
[Abstract]:As the key link of smart grid construction and the link of power transmission, transmission line is an important part of power system. Once the operation failure occurs, it will lead to the collapse of regional power system, resulting in serious power network accidents. In order to ensure the safety, reliability and stability of transmission lines, the construction of on-line monitoring of transmission lines is very important to avoid power network accidents and ensure the safety of transmission lines. According to the typical engineering application experience of on-line monitoring of transmission network in China, this paper probes into the relevant technology support of smart grid, and studies the key technology of long-distance on-line monitoring of transmission line. In order to monitor the real-time transmission line body and surrounding conditions. This paper mainly includes the type selection design of monitoring device, the power supply design of front end monitoring device and main station, the transmission and communication design of monitoring data, and the field survey of key hidden trouble lines and the application design of related on-line monitoring device. Finally, the concrete application effect after the system pilot construction is analyzed in detail. Through accessing the system, a large number of actual operation data of transmission line are accumulated, and the safety management level and operation level of transmission line are improved significantly. The hidden trouble of high voltage key lines is controllable, controllable and in control, which provides an important practical basis for the development of smart grid and the continuous deepening of on-line monitoring.
