摘要:
为了在除冰的同时，达到不影响电网连续供电、不改变电网潮流分布、不向电网注入谐波的目标，提出采用高频大电流通过输电线路与外加滤波装置构成回路的方式除冰的方法。高频大电流的集肤效应明显，导线发热功率高。计算及仿真结果表明，提出的除冰方法效果明显，操作方便。
The de-icing method is given that the high frequency large current flow past transmission lines and extra filtering device forming the circuit. The method ensures to remove ice, at the same time not to affect the continuous supply of power, not to change the power distribution network and not to inject harmonics to the grid. High frequency large current has obvious skin effect and wiring heating power high. The results of si-mulation and calculation show that it has obvious effect and easily operates.
