The Design And Implementationof Chang Chun Shuang Long Substation 66kV

Changchun Shuanglong start construction planned area 8.25 square kilometers, at present, a new 66kV substation west of the region away from the power supply area 8.9km, unable to provide adequate and reliable power supply for the region, so the development of the feasibility study report and Shuanglong 66kV substation design implementation to meet the power supply in the area.Changchun is introduced after Shuanglong substation project construction significance and the necessity, for domestic and foreign research status quo of substation do the induction and summary of the system. First systematically introduces the substation of basic theoretical knowledge, including the concept of substation and its effect, can use the methodology of substation construction. Secondly analyses the present situation of power grid construction in Changchun and the recent power grid construction projects, and about the present situation of Changchun substation load and made detailed analysis of load forecasting. Again to Changchun Shuanglong 66kV substation design principles, at the beginning of the main transformer, selection of main wiring and fitting scheme and technical analysis to introduce the system. Then analysis is introduced in Changchun 66 kv substation implement solutions, including the selection of circuit form and conductive area analysis, the choice of the main transformer, secondary system of power system relay protection analysis, system analysis and short circuit current calculation of communication. Finally stressed the Changchun Shuanglong 66kV substation matters that should be noticed in design and construction as a whole.66kV substation cable fault, vacuum breaker failure, voltage transformer failure, should pay attention to the maintenance of transformer substation in the process of construction, strengthen the substation equipment reformation, improve the system of equipment maintenance regularly tour, combined with other areas of the operation situation of 66kV substation and experience, to protect the construction and maintenance of Shuanglong 66kV substation.
