Abstract
With the development of grid and high pressure of the formation of large-capacity power grids, electricity to the national economy and social development has brought about tremendous power and effect, and social development and become indispensable to people's daily lives, one of the energy. Distribution design for industrial production and has become an important power system issues. The main graduation project of the West Industrial Park on a factory 35kv substation design a system, through the design analysis of raw data for the west of the electricity plant construction and inspection, a preliminary program to determine its power supply system. For each workshop, as well as each group to calculate the load equipment, statistics and the total load power factor, as well as the loss of electric power system; calculated, and then to determine the main step-down transformer substation of the number and capacity, power factor compensation package. Determine the basis of design information into the power lines and power sources, the development of the power supply system map. Primary system and then its corresponding short-circuit calculations and the choice of high and low voltage equipment and calibration, the final design of relay protection.
