高海拔地区紧凑型输电线路的无线电干扰研究

以500 kV德宏紧凑型输电线路为例,分析了其可能采用的导线型号、分裂方式和导线排列方式。采用国际公认的、经过实际工程验证且广泛使用的计算分析方法,研究了高海拔地区条件下,改变导线排列方式、导线型号以及导线分裂间距时,线路导线表面最大电位梯度和无线电干扰的横向分布水平。根据计算结果,确定了满足无线电干扰水平的导线排列方式、导线型号和导线分裂间距。

Radio Interference Research of Compact-type Transmission Line in High Altitude Localities

This paper takes the 500 kV Dehong compact-type transmission line as the example to analyze the possible conductor type,conductor splitting spacing and conductor arrangement.The internationally accepted and verified computation methods are adopted to study the maximum electric potential gradient of conductor surface and radio interference under different conditions of conductor arrangement,conductor type and the conductor splitting spacing in high altitude localities.According to the calculation results,the conductor arrangement,conductor type and conductor splitting spacing are determined which are suit for radio interference level.
