Abstract Because of industrial restructuring and relocation of some factories in a metallurgical research institute，the improvement on the power supply and distribution system needs to carry out. The energy-saving design in the improvement of the power supply and distribution system is expounded. Electric energy loss of the power supply and distribution system is analyzed. Three energy-saving technical measures such as reasonable choice of the transformer，line loss reduction，and power factor improvement are introduced. Electric energy loss and operating costs are analyzed.

Key words Power supply and distribution system Energy-saving Power loss Electric energy loss
