Study on Electromagnetic Environment for 1000 kV AC Power Transmission Line

Based on summarizing the domestic and international research results of electromagnetic environment for UHV power transmission line, and combined with the calculation and analysis of electromagnetic environment parameters for major tower and conductor type of preliminary design of UHV power transmission line in China, the suggestions for parameter indexes control of electromagnetic environment for 1 000 kV power transmission and transformation project such as power frequency electric field, power frequency magnetic field, radio influence and audible noise were put forward. The suggestions in the area that public is close to easily show that the limited value of electric field intensity for the line of crossing highway is 7 kV/m, the limited value of electric field intensity for the line of crossing farm is 10 kV/m, the design value of anti-radio-influence is 55~58 dB, the design standard for audible noise control is in 55 dB etc..
