一种线路交流融冰方法及装置
摘要：
本发明提供了一种线路交流融冰方法及装置，线路交流融冰装置连接融冰线路的一端，融冰线路的另一端连接融冰电源，线路交流融冰装置包括控制部分和阻抗补偿部分，阻抗补偿部分包括接于融冰线路一端的感性阻抗补偿支路和容性阻抗补偿支路，控制部分的信号输入取自融冰线路，控制部分的信号输出端至阻抗补偿部分。本发明中，控制部分根据融冰电源和融冰线路的参数情况，预估计出融冰线路的融冰电流，根据该预估计融冰电流与融冰电流目标值的比较结果，对长线路和短线路进行初步判断，然后控制感性阻抗补偿支路和/或容性阻抗补偿支路的投退，通过调节感性阻抗补偿支路阻抗值，使融冰线路中的融冰电流达到融冰电流目标值的预设范围，直到融冰结束。
摘要（英）：

This invention provides a circuit alternating current (AC) ice melting method and a circuit AC ice melting device, the circuit AC ice melting device is connected at one end of an ice melting circuit, the other end of the ice melting circuit is connected with an ice melting power source, the circuit AC ice melting device comprises a control part and an impedance compensation part, the impedance compensation part comprises an inductive impedance compensation sub-circuit and a capacitive impedance compensation sub-circuit which are connected at one end of the ice melting circuit, signal input of the control part comes from the ice melting circuit, and a signal output end of the control part is connected to the impedance compensation part. According to parameter situations of the ice melting power supply and the ice melting circuit, the control part per-estimates ice a melting current of the ice melting circuit, a long circuit and a short circuit are preliminarily judged according to a comparative result of the pre-estimated ice melting current and an ice melting current target value, then the inductive impedance compensation sub-circuit and/or the capacitive impedance compensation sub-circuit are/is controlled to fall in, through adjustment of an impedance value of the inductive impedance compensation sub-circuit, and the ice melting current in the ice melting circuit is enabled to reach a pre-set range of the ice melting current target value until ice melting is completed.
