Electrical Design Of The Power Supply And Distribution System For 10kV Substation In A University Campus

With the rapid development of economy, Greatly increasing demand for electricity, The requirements and the number of power distribution equipment are gradually improved, The construction of substation is very important. While the design and construction of terminal substation of 10 k V need to consider the construction site of the geographical conditions and other factors.Substation is the key position of electric power system, Whether its reliable operation directly affects the reliability of power supply. This design is mainly to complete the electrical design of the power supply and distribution system in the10 k V substation, Selection of representative buildings in the campus, Come to the specific design of its power supply system. Collect the original information of the school district. Including its geographical environment. The layout of the campus and the use of electricity load etc; The basic survey of load data and substation is analyzed,Comprehensive consideration from the aspects of safety, reliability, economy etc, The main wiring forms of each part are determined, The capacity and the model of the transformer are determined by the load calculation; The maximum continuous operating current and short circuit calculation of the various loops are calculated according to the calculation, To determine the type of electrical equipment, Including circuit breakers, bus, power cables, transformers etc; At last, the relay protection and lightning protection of substation are determined, The electrical design of the power supply and distribution system for 10 k V substation is completed.
