Substation design quality is good or bad, is directly related to power system security, stability and economic operation, to meet the growing needs of urban capacity, improve reliability of supply to consumers and power quality. This study focuses on the design of an enterprise 10kV substation, an overview of the basic process of substation design and methods. First analysis of the power supply system; then introduces the main power supply wiring design and the choice of the main terminal, according to the Machinery Plant Load the raw data and the choice of main transformer and its capacity to identify and model the main transformer capacity; then made on the 10kV substation electrical equipment short-circuit current calculation and the choice of short-circuit current is behind the selection of equipment to provide a basis for short-circuit current can be conducted in accordance with tuning and calibration of equipment; followed by the secondary circuit of the power distribution design and the main t...
