| Abstract: | The environment electromagnetic field pollution problems caused by indoor distribution substation busbars and its research situation around the world are described. A simplified calculation model of magnetic field from substation busbars is established. Analytical method and 2D finite element method are used in the calculation, considering the busbar structure such as its length, spacing and height in detail. The calculation results of these two methods are compared; and the applying limit of 2D finite element method is proposed. The research results are useful to protect environment from magnetic field risks. |
