摘　　要：我国冬季出现的输电线路覆冰的情况严重影响电力系统的可靠运行,文章针对此情况联系前期研究的同期并网装置转换为统一潮流控制器后具有控制潮流的功能,提出了一种基于电网间同期并列的统一潮流控制器通过传输功率使覆冰线路过负荷、负载电流增大而融冰的方法。并通过PSCAD/EMTDC进行仿真,实验结果表明进行一定的功率传输后,覆冰线路上的负载电流能够达到融冰效果,从理论上说明了通过功率传递进行线路融冰的可行性和有效性。The ice-coating of transmission lines occurred in winter seriously affects reliable operation of power grids in China. In allusion to this situation and considering the result of earlier research that after the synchronizing device turned into unified power flow controller （UPFC） the synchronizing device possesses the ability of power flow control, such an ice-melting approach that the ice-melting is carried out through enlarging the load current of ice-covered tie line to make the tie line overloaded by the UPFC based on the synchronizing device is proposed and simulated by PSCAD/EMTDC and simulation results show that the load current of the ice-covered tie line can play the role of ice-melting. The feasibility and effectiveness of ice-melting by power transmission are theoretically explained.
