| Cloud Guangxi railway is a national "long-term railway network plan" in the railway,is an important part of Guangkun China high-speed railway planning "eight vertical and eight horizontal" high-speed railway network,railway is an important channel of Yunnan to the eastern coastal areas,is an important part of Yunnan railway eight Yunnan four exit".Cloud Guangxi Railway(Yunnan section)east of Funing County,Guangnan County,Maitreya City,Qiubei County,Shilin County,Yunnan province railway length 434km,along the ten newly built traction substation.Based on the cloud Guangxi railway 220kV external power supply project with traction dragon leather as the research object,according to the operation characteristics and requirement of high speed railway traction,impact analysis,access to the railway traction variable load of power grid in Wenshan at the same time,according to the structural characteristics of Wenshan power grid,the greasy leather dragon traction traction 220kV external power supply feasibility engineering,explores a comprehensive,objective,scientific,combined with all the requirements of the system scheme and engineering scheme is studied and the preliminary design.This paper also combined with environmental protection,energy saving,green line resistance,low carbon concept,put forward the requirements of environmental protection and energy conservation line engineering and technical measures,and from the aspects of route optimization and equipment selection are discussed on the project of disaster mitigation.According to the actual situation that the power supply reliability of the project is higher,the detailed power supply scheme is put forward,and the feasibility of the project is enhanced.Based on the cloud Guangxi railway 220kV external power supply project with leather design and preliminary research on Dragon traction scheme becomes the feasibility of Yun Gui railway 220kV external power supply project with construction drawing design of leather dragon traction laid a solid foundation.At present,the external power supply project of Yunnan Guangxi railway 220kV has been put into trial operation in October 2016,providing a strong guarantee for the debugging and operation of Yunnan Guangxi railway. |
