摘要
我国西北沙漠地区能源丰富,是我国重要的能源基地和电力送端,但是区域内存在的沙尘暴极端环境,给电网建设及运行维护带来了巨大的挑战。为此整理并总结了沙漠区域与输电相关的研究现状,提出了沙漠区域输电亟需解决的关键问题,主要包括:回顾了沙漠区域电力外绝缘的研究进展,分析表明沙漠区域强风和强污秽仍是电力外绝缘的重要影响因素;综述了沙尘暴对输变电设备损伤的研究现状,提出了建立沙漠模拟环境来研究风致振动、风沙侵蚀等对电力设备的可靠性影响;总结了沙尘暴监测的技术发展,建议发展卫星遥感、雷达监测以及光纤传感等技术来建立沙尘暴的电网监测预警机制以及应急防御体系。
Possessing abundant energy in northwest desert regions of China, these regions become energy bases and power sending end, but severe storm in the regions brings the challenge to the construction and safety operation of regional power grid. On the basis of summarizing the status of technical research on power transmission in desert areas, we put forward the key prospect of power grid that should be resolved urgently. Firstly, the research progress in external insulation is reviewed to find the focus of power delivery in desert areas, and it is found that the important influential factors on the external insulation are high wind and heavy pollution. Secondly, the comment of research status is highlighted on the damages of sandstorm on transmission and transformation equipment. It is proposed that the laboratory of desert environment simulation should be established to research the wind-induced vibration of power equipment, and a synthetic effect of wind and sand dust should be considered. Finally, technological development is summarized on sand storms monitoring, and the suggestion is presented that applications of remote sensing, radar monitoring, and optical fiber technology should be reinforced in the power monitoring and warning mechanism for sand storm and emergency defense system for power grid in desert areas.
