500kV输电线路电磁环境的matlab仿真分析

运用MATLABGUI平台进行编程仿真，以正三角排列的架空线路为例建立评价模型，对500kV输电线路周围的电磁环境进行仿真研究：分析了相导线对地高度、相间距离、分裂导线根数、分裂间距、分裂导线子导线半径的变化对工频电场、工频磁场、无线电干扰和可听噪声的影响，依据相关的限值要求提出了控制措施。

Matlab Simulation Research on Electromagnetic Environment of 500 kV Transmission Lines

Using the platform of MATLAB GUI to programme and simulate, with the triangular overhead transmission line model as an example, this paper set up an evaluation model to do the simulation study on the electromagnetic environment of the 500kV transmission line. The influence with different conductor height, phrase distance, numbers and spacing of the split conductors, and the diameter of the sub-conductor on the pow- er frequency electric field, magnetic field, the radio interference （RI）, and the audible noise （AN） are analyzed. According to the request of control index, some control methods are proposed.
