【摘要】：电力系统是当今社会经济发展的重要支柱,随着社会经济的不断发展,对电力供应提出了更高的要求,保障电网及电力设施的安全运行成为电力工业的首要任务。但是一直以来电网事故的频发导致国家和人民产生了诸多的经济损失。之所以频发的最主要原因是电力设备触点温度过高易引起火灾,因此对电力设备的触点温度进行有成效的监控是减少安全隐患的重要措施。本文依据电力电网设备温度测量之切实情况,对以新型的光纤温度传感器为基础的电网温度监测应用系统进行研究。主要研究内容如下:阐述了以热致色变技术实现温度监测为基础的光纤温度传感器的原理;完成了高电场强度及高磁场强度下光纤温度传感器的设计及研制;同时以物联网技术为基础,制定电网温度监测应用系统的设计方案,完成温度监测应用系统软件的初步开发工作;完成温度监测应用系统在变电站的软硬件部署;对回传数据、可视化显示、智能分析、数据监控等进行研究,从而起到预防电网安全隐患的作用。
[Abstract]:Power system is an important pillar of social economic development. With the continuous development of social economy, higher requirements for power supply have been put forward, and ensuring the safe operation of power grid and power facilities has become the primary task of power industry. However, the frequent occurrence of power grid accidents has caused a lot of economic losses to the country and people. The main reason for frequent occurrence is that high contact temperature of power equipment can easily lead to fire, so effective monitoring of contact temperature of power equipment is an important measure to reduce the hidden danger of safety. According to the actual situation of temperature measurement of power grid equipment, the application system of power network temperature monitoring based on new fiber optic temperature sensor is studied in this paper. The main research contents are as follows: the principle of optical fiber temperature sensor based on thermochromic technology is described, and the design and development of optical fiber temperature sensor under high electric field and high magnetic field intensity are completed. At the same time, based on the technology of Internet of things, the design scheme of the temperature monitoring application system of power network is established, and the preliminary development of the temperature monitoring application system software is completed, the software and hardware deployment of the temperature monitoring application system in the substation is completed, and the data is transmitted back to the substation. Visual display, intelligent analysis, data monitoring and other research, so as to prevent potential security problems in power grid.
