Environmental impact assessment of electromagnetic radiation of power transmission and transformation projects in some areas of Xinjiang

目的为了进一步监管电磁辐射对环境的影响,对新疆部分地区做了电磁辐射评价。方法选取新疆维吾尔自治区已经建成的110、220和750 kV变电站及输电线路,跟据HJ 681-2013《交流输变电工程电磁环境监测方法》的要求,分别监测其距地面高1.5 m处的电场、磁感应强度。结果电场和磁感应强度测量结果的最高值为110 kV输变电工程变电站292 V/m、1.397μT。输电线路1 282.6 V/m、0.085μT;220 kV输变工程变电站1 784 V/m、2.506μT,输电线路1 507 V/m、0.567μT;750 kV输变电工程变电站1 144.88 V/m、0.422μT,输电线路5 952.4 V/m、2.523μT。结论监测结果表明新疆地区不同高压输变电工程的电磁辐射水平符合国家环境电磁波卫生标准。

Objective To further monitor the impact of electromagnetic radiation on the environment,conduct electromagnetic radiation evaluation in some areas of Xinjiang. Methods The established 110,220 and 750 kV power transformer and transmission lines in Xinjiang Uygur Autonomous Region were selected,to detect the intensity of electric fields and magnetic fields from the ground height 1.5 m respectively according to the requirements of the Electromagnetic environmental monitoring method of AC transmission and transformation project(HJ 681-2013). Results The maximum measurement values of electric fields and magnetic fields were as follows:292 V/m and 1.397 μT for substation,1 282.6 V/m and 0.085 μT(110 kV) for transmission line,1 784 V/m and 2.506 μT for substation,1 507 V/m and 0.567 μT(220 kV) for transmission line,1 144.88 V/m and 0.422 μT for substation,5 952.4 V/m and 2.523 μT(750 kV) for transmission line. Conclusion The results show that the electromagnetic radiation level of different high voltage lines in Xinjiang region is in good agreement with the health standard of national environmental electromagnetic wave radiation.
