天然气热电联产升压站工程电磁环境监测与评价

Electromagnetic Environmental Monitoring and Evaluation on Booster Stations of Natural Gas Cogeneration Project

依据国家相关标准对近三年内投运的三座220kV天然气热电联产升压站周围电磁环境进行监测与评价。通过监测结果评价得出了上述升压站周围工频电场、工频磁场和无线电干扰水平符合标准要求。结果表明:随着与升压站距离的增加,工频电场、工频磁场递减趋势明显,无线电干扰随距离衰减趋势不明显。天然气热电联产升压站工程对环境的电磁影响是可以接受的。

According to the national standard,the article aims to monitor and evaluate the electromagnetic environment of the three 220kV booster stations of natural gas cogeneration project which are put into operation in three years. The measurement results show that the levels of electric field, magnetic field and radio interference are all lower than the limits defined by environment protecting standard. As the distance to the booster increases, the decline trend of electric field and magnetic field is obvious while that of the radio inter-ference is not that obvious. The electromagnetic impact of the booster stations of natural gas cogeneration project is acceptable.
