Abstract：With the development of information technology, the demand of national economy for digital city, green and intelligent building is higher and higher, and modern, electrification, high-rise, high-level, dense large building groups are generally built. With the increase of equipment capacity, the substation with high voltage and large capacity is built on the power load center, and the electrical range of building is expanding. This design is the design of power supply and distribution system for No. 1 teaching building, which includes load calculation, reactive power compensation, conductor and cross section selection, substation, relay protection, lighting, lightning protection and grounding. The design must take into account the safety, reliability and economy of the power supply system. Through the design of the main wiring, the calculation of short-circuit current, the determination of the type and parameters of the main electrical equipment, the dynamic and thermal stability calibration of the electrical equipment, the design of reactive compensation, the design of lightning protection and over-voltage protection device, the design of the power system is completed in detail.

Key words: power supply and distribution system design; lighting design; lightning protection and grounding design
