In view of the noise influence of high voltage shunt reactor on environment and its control requirements at high voltage substation

the influence factor and control measures of the noise of high voltage shunt reactor is studied by experiment. In this paper

the sound power levels of 111 units of 500 kV high voltage shunt reactors in 37 groups of 15 substations in Hubei Province are actually measured by the improved sound intensity method and analysis is performed. Ii is show by the test result that the maximum acoustic power level of the reactor increases gradually with the increase of operation life. Since the increase of rated capacity and voltage of equipment

new insulation materials and design schemes will play a role in reducing vibration and noise to a certain extent. At the same time

adoption of surrounding arrangement of radiator of the reactor can also achieve the noise control. In view of noise control of high voltage reactor

the corresponding control measures from such aspects as sound source control and propagation process control is proposed in this paper. The sound source is controlled mainly by improving material and design. The noise reduction treatment of certain 500 kV substation is taken as an example;the dissemination process control takes the noise reduction treatment of a 500 kV substation as an example. Taking the noise reduction treatment of a 500 kV substation as an example

a noise barrier control scheme is proposed by the use of Sound PLAN noise analysis software to reduce the average noise pressure level by about 6 dB（A）

so as to meet the requirements of noise control. The study content of this paper is of great significance for guiding the design of substation and noise reduction.
