四川电网配电网交流融冰方法应用研究

Application Research on AC Iee melting Method to Distribution Network in Sichuan Power Grid

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。

Abstract:

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．
