Feasibility Demonstration Of Electrical Part Of 110kV Cuiyun Substation Power Transmission And Transformation Project

With Pu’er Ecological City creating, two large pumping station build for water diversing at Zhonghe river in Liushun area, and the load growing, the existing substation capacity can not meet the needs of the development of the load.In order to meet the new load demand for electricity, strengthening and improving the Liushun area surrounding 35kV Power Grid Structure and improve the area power supply reliability, Cuiyun 110kV power transmission project needs to be implemented.The 110kV Cuiyun power transmission project as the research object, for in Liushun area 110kV substation construction the necessity analysis, the feasibility of the construction of the project in the design of electrical were studied.Firstly, introduced the background of the research project, Pu’er City’s natural and economic survey and current situation of power grid is analyzed and the load development of Simao district are predicted, and the contradictions and problems in the regional power supply and demand of energy is proposed. Secondly, the necessity of building a 110kV substation in the Liushun area is pointed out with the development plan of Pu’er electric power network. Finally, through the present situation on the local power grid analysis, determine the 110kV Cuiyun variable access mode, transformer selection, and through the short-circuit current calculation, electric secondary equipment, communications equipment, to change the selection, of 110kV Cuiyun substation power transmission project electrical part design can line are analyzed in detail.
