Study on the Power Frequency Electromagnetic Environment of Accessory Substation and the Relevant Shielding Measures
Abstract: As a novel type of substation, the accessory substation puts forward strict requirements to the power frequency electromagnetic environment. In this paper, the novel accessory substation was taken as the research project. Transformer and bare busbar were confirmed as main electromag-netic disturbance sources. Simulation by using of Ansoft/Maxwell was developed to describe the spatial distribution of the power frequency electromagnetic field and its property that the filed intensity delays with the increase of the distance. In order to further weaken the electromagnetic field, some shield materials were set inside the wall of substation. The shielding effectiveness of the different structures and different electrical characteristics of shield materials were compared and analyzed. Eventually the guidances for the design of power frequency electriomagnetic shielding of accessory substation were proposed.
