The Design Of The Standard Distribution110kV Intelligent Substation

The intelligent substation evolves from the digital substation. Among the intelligentsubstations, the standard delivery smart substation is based on the latest technology, withintelligent operation, low carbon release and high efficiency. Especially the standarddistribution110kV substation is an important part of a new generation of the intelligentsubstation developed by the State Grid Corporation. And it has become a hot topicrecently as well.This thesis aims at the design of the standard distribution110kV substation. The mainresearch contents are as follows:First, the design principles of the standard distribution of intelligent substation areintroduced. According to the different types of substation. Prefabricated cabin for thesecond combination is presented in details, including its definition, structure types, thesetting principles, the internal layout and so on.Secondly, combined with the actual background of the engineering, the generaldescription of the regional electric power system around the site of the designed intelligentsubstation is analyzed. Based on the results of load forecasting, the necessity of theengineering construction is discussed. The scale and scope of the substation constructionis clarified, and the short-circuit current is calculated too.Thirdly, according to the status of the regional electric power system， thedevelopment of load, the results of the electrical calculations, the substation is designed indetail, as well as the main electrical wiring and the electrical layout design. The mainelectrical equipments are selected. The system relay protection and the dispatchingautomation are all designed. The communication scheme is described. A full descriptionof the situation of station site, the construction and structure, the water supply anddrainage, heating ventilation air conditioning, the fire control and so on are also given.Finally, the main electrical wiring diagram and the electrical layout drawing arepresented. The standard distribution and the configuration of intelligent system of thissubstation are discussed in detail. The design has been already applied to the engineeringconstruction.
