摘要
高压输电线路周围的电磁环境是影响线路工程规划和建设的重要影响因素之一。根据井冈山220 kV水电厂送出工程规划情况,建立了220 kV线路以及220 kV和500 kV线路平行段的二维电磁场仿真模型,计算电磁场分布情况并分析其电磁环境对周边居民住房的影响,根据电磁场标准限值要求,确定线路下方建筑的高度限值;根据平行段线路电场计算结果,综合考虑了线路风偏的影响,确定了平行段线路之间的距离。本文计算方法可为输电线路电磁环境分析提供借鉴,计算的结果为实际工程的规划设计提供了强有力的理论支撑。
The electromagnetic environment around high voltage transmission lines is one of the important factors affecting the planning and construction of transmission lines.According to the planning of Jinggangshan 220 kV hydropower plant,the two-dimensional electromagnetic field simulation model of 220 kV line and 220 kV and 500 kV line parallel sections was established to calculate the distribution of electromagnetic field and analyze the influence of electromagnetic environment on the surrounding residential housing.According to the electromagnetic field standard limit requirements,the height limit of buildings below the line was determined.According to the calculation results of the electric field in the parallel section,the distance between the lines in the parallel section was determined by considering the influence of wind deviation.The calculation method proposed can provide a reference for the electromagnetic environment analysis of transmission lines,and the calculation results provide a strong theoretical support for the planning and design of practical projects.
