Design And Application Of The 110kV Tangshan Bubuchuan Smart Substation

As an important support and foundation of strong smart grid, smart substation is an important part of the whole power grid construction. A new generation of intelligent substation in the system is highly concentrated, structure, rational layout, equipment is advanced and applicable, economy energy conservation and environmental protection, support regulation of various "as the goal, can solve the intelligent substation installation of complex, long construction period, operation and maintenance difficulty, high cost, is the future direction of the development of Smart Substation. Therefore, the construction of a new generation of smart substation has a very important theoretical and practical significance.In this thesis, the design and application of a new generation of 110 kV substation in Tangshan is studied. First completed the demand analysis and the overall planning, gives the scheme of the overall design scheme and system, to meet the general design specifications, in line with the basis of a new generation of intelligent station requirements, combined with operation conditions in the local area, by choosing the new intelligent equipment, so as to raise the overall substation intelligent level. Then, a system of 110 kV substation in Tangshan is designed and the equipment selection is carried out.Combining with the present situation of the development of equipment, the GIS Engineering pass in and out line in the spacers of the electronic current and voltage combined type transformer; 110 kV and 35 kV and 10 kV main transformer wire spacing using electronic transformer and intelligent components to realize the intelligent primary equipment. Finally design the Tangshan step by step Sichuan 110 kV substation secondary system, intelligent selection of secondary equipment, station utility, 110 kV and main variable interval at the bay level equipment layout in type II prefabricated cabin, cabin equipment used before connection of display device, to realize the design idea of the prefabricated cabin layout. Use of prefabricated cable technology, to achieve a two equipment and equipment of cable, cable connection standard, improve the two cable construction neat and beauty, and greatly shorten the construction period.Currently the substation has entered the commissioning phase, due to the design according to the State Grid Corporation of the new intelligent substation design specification requirements, and give full consideration to the influence of the local natural environment of equipment layout, in order to meet the demand of intelligent station based on the requirements of design and reasonable layout and save the area, reduce the construction investment.Area where the project for high pollution level area, of polluted areas have certain reference significance and station for a new generation of intelligent design provides a reference and can provide for the later construction of Smart Substation to exemplary role.
