中文摘要:

提出了一种基于链式STATCOM的线路防冰融冰方法，分析了输电线路覆冰时的等效模型并研究了融冰时的热交换过程，针对6kV输电线路计算出了线路融冰所需要的保线电流和最大融冰电流值，根据计算结果设计了融冰系统的主电路拓扑，并对相关的融冰控制策略进行了分析和研究，最后采用MATLAB对模拟系统进行了仿真，仿真结果表明，该融冰装置可以对无功电流进行柔性调节，能够满足融冰的需求。

英文摘要:

To improve the application of AC ice—melting technology in power grids,a new type of based on cascaded STATCOM ice—melting technology was proposed.Based on analysis on the equivalent model of frozen transmission lines and the heat exchange during ice-melting,the necessary anti—icing current and maximum current were calculated for a 35 kV power line,according to the calculation results.The main circuit topology was designed,mathematical model and control strategy of the power unit module were introduced and discussed.Finally By using matlab ,the simulation is made.,Test results show that the ice—melting device can regulate reactive current output flexibly。
