Electromagnetic Environment and Corona Control Measures of UHV Substation

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.
