摘　　要：四川电网冬季配电网线路融冰需求较为迫切。通过综述在四川电网运用较为广泛的配电网线路交流融冰方法的技术原理、特点、适用范围,经对比:现有交流融冰方法由于融冰电流无法调节,因而存在较大适用局限性;变压器串联交流融冰方法作为其有效补充,提高了现有交流融冰方法的适用性;电容串补交流融冰方法可以调节交流融冰电流,具有较广的工程应用价值。AC ice - melting is in a great demand of distribution network in Sichuan power grid. The principle, characteristics and application scope of AC ice - melting method which is used commonly in Sichuan power grid are summarized. Through comparison , the existing AC ice - melting method has some limitations due to the fixed ice - melting current. As a beneficial supplement to AC ice - melting, the AC ice - melting using transformers in series improves the applicability of the existing method. The AC ice - melting using series capacitor compensation has a wider application prospect because of its adjustable ice - melting current.
