Abstract:With the rapid development of China s national economy and the gradual expansion of power grid scale, power grids in some mining areas are no longer suitable for modern industrial power demand, which leads to poor operation of distribution systems in mining enterprises and drop of power factor and voltage of distribution networks. It is necessary to further optimize the energy distribution system of metal mine power grid and add dynamic energy compensation devices for real-time network tracking, so as to improve efficiency and energy quality and save operating costs.
