【摘要】：輸電線路分布區(qū)域廣、傳輸距離長、地形條件復雜,超高車輛線下通行或超高機具線旁作業(yè)等外力破壞引發(fā)線路斷裂、短路,造成設備跳閘、停電等事故時有發(fā)生,既給用電企業(yè)造成了經(jīng)濟損失,也對電網(wǎng)安全運行構成了嚴重威脅。由于這些外力破壞事件的發(fā)生具有經(jīng)常性、隱蔽性、突發(fā)性,致使供電部門日常巡視難以達到理想的管控效果。為了保護輸電線路的安全,預防輸電線路外力破壞隱患,本文設計和開發(fā)了一套輸電線路防外力破壞預警系統(tǒng),旨在有效減少或消除外力破壞事故,提高輸電線路安全運行和智能化管理水平。主要內容包括:①總體方案設計:為了降低距離檢測裝置的體積、重量和功耗,將距離檢測和自動報警分開部署,利用短程無線傳輸方式將二者關聯(lián)。結合系統(tǒng)功能需求分析,闡述總體結構以及測距單元、短程無線傳輸和遠程無線傳輸方案選擇,并介紹信息融合處理技術及其算法。②硬件電路設計:依據(jù)輸電線路防外力破壞預警系統(tǒng)整體結構,確定主控芯片選型,詳細闡述線上測距裝置、現(xiàn)場告警終端、短程通信單元和遠程通信單元等硬件電路的設計思想和實現(xiàn)方案。③軟件程序設計:根據(jù)輸電線路防外力破壞預警系統(tǒng)的功能特點,闡述軟件設計原則和思想以及線上測距裝置、現(xiàn)場告警終端和后端預警平臺涉及的軟件程序設計流程。通過實測驗證了本文研發(fā)的輸電線路防外力破壞預警系統(tǒng)的主要功能和技術指標,結果表明,該系統(tǒng)預警功能響應快、準確率高、運行可靠,能對輸電線路線旁和線下外力破壞隱患目標進行有效的距離探測,對超過安全距離的行為做出準確判斷并及時告警,后端預警平臺能實時獲取危險點隱患信息,達到了設計目標。
[Abstract]:Transmission lines are widely distributed, long transmission distance, complex terrain conditions, ultra-high vehicles under the line or ultra-high machine line side operation and other external force damage caused by line breakage, short circuit, resulting in equipment tripping. Power outages and other accidents occur from time to time, which not only cause economic losses to power enterprises, but also pose a serious threat to the safe operation of power grid. In order to protect the safety of transmission line and prevent the hidden trouble of power transmission line damage, the daily inspection of power supply department is difficult to achieve the ideal control effect. This paper designs and develops a set of early warning system against external force damage of transmission lines, which aims to effectively reduce or eliminate external force damage accidents. In order to reduce the volume, weight and power consumption of the distance detection device, the distance detection and automatic alarm are deployed separately. Combined with the analysis of the system functional requirements, the overall structure, ranging unit, short-range wireless transmission and remote wireless transmission options are discussed. The information fusion technology and its algorithm .2 hardware circuit design are introduced. According to the whole structure of the transmission line anti-damage warning system, the selection of the main control chip is determined, and the on-line ranging device is described in detail. The design idea of the hardware circuit such as alarm terminal, short range communication unit and remote communication unit, and the design of software program. 3. According to the function characteristic of the transmission line anti-damage warning system. The principle and idea of software design and the on-line ranging device are described. Field alarm terminal and back-end warning platform involved in the software design process. Through the actual test to verify the transmission line anti-damage warning system of the main functions and technical indicators, the results show. The system has the advantages of fast response, high accuracy, reliable operation, and can effectively detect the hidden danger target by the external force along and below the transmission line. When the behavior over the safe distance is judged accurately and alerted in time, the back-end warning platform can obtain the hidden danger information in real time and reach the design goal.
