Study of the electromagnetic field distribution inside a HV/MV substation

摘要

The electromagnetic field interferences (EMI) can influence both human health and functioning of electrical appliances. An EMI map is an important instrument for monitoring the health exposure limits versus the standards. In order to draw an EMI map measurement methodologies and advanced computational models are required. In case of high voltage (HV) and or medium voltage (MV) substations the numerical simulation has several advantages because it does not require investment in measurement devices and operative personnel and can easily analyze complex working scenarios covering both substation yard and its neighborhoods. Examples of numerical simulations are presented on the 3D model of the 110/20 kV substation named Biharia in order to visualize the electromagnetic field and to make comparisons with the professional human exposure limits.
