The article presents a method of calculating geoindutsirovannyh currents at high geomagnetic storms in the power lines power supply systems. The flow geoindutsirovannyh currents in power lines can lead to saturation of the magnetic system of power transformers, tripping of relay protection and automatic shutdown and power lines. To calculate geoindutsirovannogo current was used straight section transmission line between two transformer substations. The estimation of the values obtained geoindutsirovannyh currents in power lines voltage class 110-330 kV at different levels of intensity of the geoelectric field, through which established that the value geoindutsirovannyh currents in power systems can be compared with operating currents of power lines. The method developed can be applied in practice to estimate the values geoindutsirovannyh currents in power lines and their effect on the operation of power supply systems.
