The invention relates to an adaptive rapid determining method for multi-medium power frequency electric field distribution, which comprises the following steps: 1, acquisition of parameters, namely, acquiring a geometric parameter, a geometric size and a space coordinate position of each medium arranged close to a working corridor in a transformer substation, and measuring relative dielectric constants of each medium; 2, determination of a power frequency electric field, namely, establishing and dividing a power frequency electric field physical model, constructing a data storage structure, determining the electric field value of each node in the power frequency electric field physical model and the like; and 3, drawing of a space electric field contour distribution map. The invention can judge whether the power frequency electric field value in the area which is 1.8 meters away from the ground or below exceeds a national regulated limit value 4KV / m; compared with a conventional method, the adaptive rapid determining method has the advantages of reducing memory demand by 70 percent, shortening calculating time by 50 percent and improving calculating precision by 5 percent. The adaptive rapid determining method for the multi-medium power frequency electric field distribution is applied to rapid determination and estimation of an on-site power frequency electric field, and a safety design of power transmission and transformation.
Description
technical field [0001] Aiming at the bottleneck problem of the current determination method of power frequency electric field distribution under the coexistence condition of multiple media such as a substation, the present invention invents a self-adaptive and rapid determination method of multi-media power frequency electric field distribution. Background technique [0002] With the continuous development of the electric power industry and the increase of the voltage level of transmission lines, the damage of power frequency high-voltage electric field to human health has aroused widespread concern. At present, there is no practical and effective method to quickly determine the power frequency electric field distribution under the coexistence of multiple media in substations. Due to the existence of multiple media in the substation, the determination of the distribution of the power frequency electric field in the substation is a complex problem that is affected by multiple...
