为降低覆冰对低压电网正常运行的影响,提出了一种基于SVG无功控制的线路融冰方法。该方法通过无功补偿控制流过线路的无功电流以增大覆冰线路的总电流,使线路产生功率损耗的热量达到融冰所需的热量,从而实现融冰目的。仔细阐述了该方法拓扑结构及其工作原理,在对SVG控制策略及检测电路深入分析的基础上,考虑覆冰情况对电网电压平衡的影响,构造了新型的检测电路以满足各检测参数的精确性。并通过Matlab对10 kV输电线路融冰模拟系统的仿真分析,其结果证明了该融冰装置能够实现精准调节无功电流来满足融冰需求。

For reducing the impact of ice coating on the normal operation of the low voltage power grid,a kind of ice?melting method of line based on SVG reactive power control is proposed.The method is to control the reactive power current flowing the line by the reactive power compensation so to increase the total current of the ice coating line and keep the heat generated by the line reach the heat required for melting the ice,thus achieving the purpose of ice?melting.The topological structure and working principle of the method are described in detail,the influence of ice coating on the balance of gr...
