【摘要】：随着经济社会的发展和科技进步,对电力供应的指标要求越来越高。电网公司在安全生产和电力供应管理等方面经投入了巨大的人力、物力和财力,加快了智能电网的建设步伐。电网设备的检修模式逐步由定期检修向状态检修转变,由带电监测向在线监测转变。因此,电网设备状态参量在线监测技术将有着广阔的应用前景。本文所研究的电网设备状态参量在线监测装置远端控制技术主要通过分析该技术的国内外研究现状、市场需求、总体设计、设备功能实现和现场测试等方面,研制出具有保证作业人员安全、抗干扰能力强、性能稳定可靠的远端控制装置。本文采用光电控制的原理设计出长距离遥控式光电开关,具有抵抗强电场、磁场等干扰能力,在不改变原电网设备接线方式及运行状态的情况下,通过远端控制开启、关闭在线监测装置和无线传输装置进行设备检测,就地显示设备状态参量测试结果。文中将远端控制装置与在线监测装置和无线传输装置进行了匹配优化,进行了现场安装调试,在线监测数据与停电检修试验数据比对分析结果正确。本文设计研制的电网设备状态参量远端控制装置适应电网发展的潮流,主要解决运行中电网设备在线监测系统的远端控制、数据无线传输中的抗干扰等应用技术问题,填补了电网设备在线监测远端控制方式的空白。通过远端控制装置的的应用,不断积累相关的运行、检测、诊断参数,推广应用适应金昌公司变电设备专业巡检的方法,科学的指导变电设备状态检修工作,达到了降低运维成本和保证电网设备安全运行的目的。本文最后对电网设备状态参量在线监测装置远端控制技术未来的发展方向进行了展望。
[Abstract]:With the development of economy and society and the progress of science and technology, the index of power supply is higher and higher. Grid companies have invested huge manpower, material and financial resources in safety production and power supply management, and accelerated the construction of smart grid. The maintenance mode of power network equipment is gradually changed from periodic maintenance to condition maintenance, from live monitoring to online monitoring. Therefore, the on-line monitoring technology of power network equipment state parameters will have a broad application prospect. In this paper, the remote control technology of the on-line monitoring device for power network equipment state parameters is mainly studied by analyzing the domestic and foreign research status, market demand, overall design, equipment function realization and field test, etc. A remote control device is developed to ensure the safety of operators, strong anti-interference ability and stable and reliable performance. Based on the principle of optoelectronic control, this paper designs a long distance remote control optoelectronic switch, which has the ability to resist the interference of strong electric field and magnetic field. It can be opened by remote control without changing the connection mode and operation state of the original power network equipment. The on-line monitoring device and wireless transmission device are closed to detect the equipment, and the test results of the device state parameters are displayed on the spot. In this paper, the remote control device, the on-line monitoring device and the wireless transmission device are matched and optimized, and the on-site installation and debugging are carried out, and the results of comparison and analysis between the on-line monitoring data and the outage maintenance test data are correct. The remote control device designed and developed in this paper adapts to the power flow of the development of the power network, mainly solves the remote control of the on-line monitoring system of the power network equipment in operation, the anti-interference in the data wireless transmission and so on. Fill in the gap of remote control mode of on-line monitoring of power network equipment. Through the application of remote control device, the related operation, detection and diagnosis parameters are continuously accumulated, and the methods suitable for the professional inspection of substation equipment in Jinchang Company are popularized to scientifically guide the condition maintenance work of substation equipment. The aim is to reduce the operation cost and ensure the safe operation of power network equipment. At the end of this paper, the future development of remote control technology of on-line monitoring device for state parameters of power network equipment is prospected.
