【摘要】：本文对电力电缆及其管沟的运行现状进行了深入分析,并对电缆及其管沟在运行管理中存在的问题加以量化分析,从而得出了对电力电缆及其管沟在线综合监控系统进行研究的必要性。本文的第二部分主要分析论证了影响电力电缆安全运行的关键因素,包括单芯金属护套接地电流、温度、火灾、电缆沟水位、防盗等,并对各因素的影响展开论证,最终得出“建立电力电缆及其管沟在线综合监控系统”是提高劳动效率及运行管理水平的必然选择。本文的第三部分对在线综合监控系统进行了总体概述,并对系统的组成结构、网络结构、集中监控中心、综合智能数据管理平台、二级远程集控平台、系统主干网络传输线路分别进行了介绍。该系统以REAL-TIME综合智能数据管理平台为核心和基础,由电力电缆线路故障测巡应用系统、电力电缆局部放电在线监测应用系统、分布式光纤测温应用系统、电力隧道井盖及出入口门禁集中监控应用系统电力隧道环境监控及设备自动化控制应用系统、电力隧道智能视频监控及入侵报警应用系统及电力隧道有线应急通信指挥人员定位应用系统组成。本文第四部分对综合监控系统的各子系统进行了详细介绍,分别从系统构成、系统功能、系统组网方式及实施方案等方面进行了论述。本文第五部分介绍了系统的实施情况及效果。本文最后一部分对综合监控系统进行了总结论述。同时,也希望在工程实践过程中能够不断检验和完善本文所探讨的内容,在实践中不断完善系统,使济南供电公司的电网运维管理水平得到提升,最终实现系统的全面推广。
[Abstract]:In this paper, the operation status of power cable and its gutter is analyzed in depth, and the problems existing in the operation and management of the cable and its gutter are analyzed quantitatively. Therefore, the necessity of the research on the power cable and its trench integrated monitoring system is obtained. The second part of this paper mainly analyzes and demonstrates the key factors that affect the safe operation of power cable, including the earthing current of single core metal sheath, temperature, fire, water level of cable ditch, anti-theft and so on. Finally, it is concluded that it is an inevitable choice to establish an on-line comprehensive monitoring system for power cable and its trench to improve labor efficiency and operation management level. The third part of this paper gives a general overview of the online integrated monitoring system, and the system structure, network structure, centralized monitoring center, integrated intelligent data management platform, two-level remote centralized control platform. The main network transmission lines of the system are introduced respectively. The system is based on the integrated intelligent data management platform of REAL-TIME. The system consists of power cable fault detection and patrol system, power cable partial discharge on-line monitoring application system, distributed optical fiber temperature measurement application system. Centralized Monitoring and Control system for well cover and entrance and exit of Power Tunnel Application system for Environmental Monitoring and automatic Control of Power Tunnel, The intelligent video surveillance and intrusion alarm application system for power tunnel and the location application system for emergency communication personnel in power tunnel. In the fourth part of this paper, the subsystems of the integrated monitoring system are introduced in detail, including system constitution, system function, system networking mode and implementation scheme. The fifth part introduces the implementation and effect of the system. In the last part of this paper, the comprehensive monitoring system is summarized and discussed. At the same time, we also hope that in the process of engineering practice, we can constantly test and perfect the content discussed in this paper, improve the system in practice, so that Jinan power supply company's management level of power network operation and maintenance can be improved, and finally the overall promotion of the system can be realized.
