1000 kV晋东南-南阳-荆门特高压交流试验示范工程已投入商业运行,3个特高压变电站集成了大量高压和二次设备,电磁环境复杂.如果变电站电磁环境影响严重,就可能会影响附近无线电台站的工作及周围居民和变电站工作人员的工作和生活.基于此,对特高压交流试验示范工程2个变电站及1个开关站电磁环境作了实测.结果表明:3个特高压变电站围墙外的无线电干扰水平满足环保要求、围墙外可听噪声与500 kV变电站水平相当、工频电磁场水平比500 kV变电站水平略大.通过数值计算及试验研究,提出了变电站可采用合适尺寸的管母或软母线型式,合适的金具型式等方法降低特高压站内电晕放电引起的无线电干扰水平及可听噪声.

The 1000 kV Jindongnan-Nanyang-Jingmen UHV AC demonstration project have been on commercial run.UHV substation integrates a series of high-voltage and secondary electrical equipments which bring out electromagnetic environment deserving more attention.If the electromagnetic environment of substation is severe,it will affect the neighboring radio stations' normal work and also the residents around and workers at the UHV substation.So we test the electromagnetic environment parameters of Chinese UHV AC substation,and test results indicate that the radio interference data 20 m away from UHV substations satisfies requests of environment protection,audible noise data is equivalent to 500 kV substations.Electromagnetic field is a bit larger than that of 500 kV substations.Paper puts forward some measurements, for instance,suitable pipe bus dimension and fittings model,to achieve electromagnetic environmental amendatory.
