Abstract
The design specification is based on folk music Deqing area for the variable distribution of the main design. Through the design analysis of raw data, the calculation of residential quarters load short-circuit calculation, select the appropriate and the number of main transformer capacity, in order to determine the specific power supply system. Primary system and then its corresponding short-circuit calculations and the choice of high and low voltage equipment check, selection and validation of high low-voltage lines. Combined with the basic knowledge of textbooks, according to our country by changing the operation of distribution and a variety of electrical equipment standards, electrical equipment specific to the security of electricity and energy savings, and come to the residential quarters of the line power supply system Fig. Strictly follow the design of electrical substation design principles.
Graduated through the design, the consolidation of the power supply system design, training and increased the independent analysis and problem-solving skills, also trained by four years of university the comprehensive application of knowledge.
