Analysis on the Application of DC De-Icer in China Southern Power Grid
摘要
Abstract
Based on the de-icing practice of China Southern Power Grid（CSG） in January 2011,the application of DC de-icers is analyzed,including the allocation of de-icers,and the efficiency and effect of de-icing.The paper concludes that the de-icing devices have played an important role in keeping the 220 kV transmission towers away from falling down and providing power supply to the county and above level cities;but that these devices be able to play a full role under severe ice-storm depends on the further perfection of CSG’s de-icing system.The paper suggests to optimize de-icing schedule,to perfect the process control of de-icing,and thus to make the DC de-icers play role in maximum.Meanwhile,the redundance of these de-icers should be properly increased,and the ability to protect networks should be enhanced by higher line-protecting ability and de-icing efficiency.Finally,it is suggested to further study the problem of ground lines iced.关键词
