【正文】 r a machinery factory in the Yellow River for distribution design. The electric power plants to some, highvoltage technology, such as protection for the theoretical basis of professional knowledge, high Voltage Substation on the main part of the plant design graduate training. Design steps include: load statistics, the load calculation, the programme, the established power, shortcircuit current, the electrical equipment selection and relay coordination and Lightning Protection, and so forth. Energy modern industrial production is the major energy and power. With the development of modern civilization and progress, social production and life to the quality of power supply and management of the increasingly high demands. Factories power supply system is the core of the substation. Therefore, the design and construction of a security, economic substation, is extremely important.
