Sustainable Mining and Metallurgy

Most mining enterprises, with large electricity loads, are located in areas without electricity which are difficult to be covered by power supply network or economically underdeveloped, hence they adopt the isolated grid self-supply mode of diesel generator unit, bringing problems such as low power generation efficiency, high power generation cost, large operation and maintenance workload and environmental pollution. By making full use of the characteristics of the energy storage system and with a view to the needs of overseas mining enterprises, a new energy storage diesel generator power supply network was built, and its network architecture, system composition and working principle were introduced. In this paper, several project cases were given to illustrate that the power generation efficiency is significantly improved, the fuel consumption per unit of power generation is reduced, the air and noise pollution to the environment is reduced, which means that it can achieve energy saving with reduced emission, increased efficiency with reduced cost as well as more environment-friendly benefits.
