Study On The Optimization Of Shuanglong ± 800 KV Converter Station

The converter station project has the characteristics of large investment,large scale,complicated construction process and cross.The construction of the project has significant political and economic significance.The project will transform the western water resources advantage into the power resources of East China.It is the strategy of implementing the western development strategy,transforming the western resources advantage into economic advantages and realizing energy saving and emission reduction.Sustainable development and promotion of China's power transmission technology upgrade,to achieve a scientific concept of development is an important project,is the rational use of transmission corridors,commutation site,the location of resources and reduce the transmission loss of major measures.The starting point for the project is Yibin City,Yibin City,Sichuan Province Ssangyong town,where the place for the hill slope,the annual rainy,mainly to cohesive soil and mudstone,geological and climate are not conducive to the smooth construction of the project,the progress of control more difficult.Through the optimization of the project preparation period,the network optimization method is used to optimize the project schedule,the optimization of the management process and the optimization of the material security are carried out to optimize the project progress.Xiluodu left bank-Zhejiang Jinhua ± 800 kV HVDC project due to the progress of control measures effective,significant,low-side 3-day advance in advance,pole I high-end 30 days ahead of charge,pole ? high-end 20 days in advance to achieve,from the civil Start to the bipolar low-end put into operation only 13 months to the bipolar high-end put into operation only 16 months of amazing performance,refresh the UHV converter station construction history of the new record.Using the optimization plan proposed in this paper,the progress of the effective control,ahead of schedule,for the State Grid Corporation has brought great economic benefits,with remarkable results.Ahead of the operation to achieve the overall goal of engineering construction,to achieve the national western development strategy,the western water resources into economic advantages,to achieve energy-saving emission reduction,west of water and electricity to the East China load center,to avoid the waste of water resources,to solve the problem of insufficient power supply in East China.
