| With the extreme global climate frequent comes,transmission line regulation harm caused by the more and more serious.All along,Domestic power enter prices and research institutes and other anti-icon the grid,had a long anti-icing technology research and exploration,and gradually formed a comprehensive system office disaster prevention technology.And because HVDC transmission has a big transmission capacity and flexible business model,its transmission distance is long,it is becoming an important national grid back bone grid component.HVDC is a transmission project that they are repeated for long-distance transmission lines to increase the probability office road.Icing on the safe operation of the DC transmission lines has a certain impact.It is becoming one of the most important reasons to determine the cost of the project.The DC transmission line icing,ice melting of ice prevention,improve HVDC project,ice resistant ability,has the important meaning for protecting the safe and stable operation of HVDC transmission project and the whole power system.But if the transmission line especially UHV transmission line with ice resistant measures to improve the design ice thickness,investment per km on the need to increase the cost of millions,a line investment increase costs at least billions.Therefore,we need to design standard of ice protection of UHV transmission lines analyzed and optimized,to achieve maximum safety and economic efficiency.The safety and technical point of view,considering the different requirements of each region and their own conditions,the economy of the transmission line,we design a low cost and high reliability,manufacture of UHV transmission system optimization design with the most preferential price. |
