可调电容串联补偿式交流融冰装置在湖南电网的应用
摘要
传统的交流融冰技术需多条线路串接
融冰时存在负荷转移困难、倒闸操作复杂等不足。文中提出了串联补偿式交流融冰技术
研制了可调电容串联补偿式交流融冰装置。装置在浏阳集里220 kV变电站完成试验
试验电流810 A
15 min后
导线温度由17℃上升至35℃。装置的成功研制为应对大规模冰雪灾害提供了一种有效的手段。
Abstract
Conventional AC de-icing technique needs several power lines to be connected in series
which could cause many problems such as load transferring difficulty
complicated breaker operation and so on.Series-wound compensation AC de-icing technique was introduced in this paper.Regulative capacitor in series compensation AC de-icing equipment was developed and testes at Liuyang Jili 220kV substation.When test current was set at 810A
the temperature of test conductors rose from 17℃ up to 35℃ in 15 minutes.The device was proved to be an effective way for resisting large scale ice storm.
