同杆双回线换位方式的比较

Transposing Manner Comparison for Doubles on the Same Tower

采用精确的分布参数模型和特征模量分解方法 ,通过编程精确计算了同杆双回线在不换位 ,少换位和 2次完全换位的不同架设方式下的有功损耗 ,负序分量 ,零序分量以及双回线间的感应电压和感应电流 ,发现在 2 ,5 ,7三种架设方式下均有一种最佳换位 (排列 )方式 ,使输电的质量最好且损耗最小。通过计算给出了在不同换位方式下的结果并提出同杆双回线换位方式的建议。

By precise model of distributed parameters and by analysis of complex matrix, the loss of active power, negative sequence component, zero sequence component and induced voltage or current between two lines on the same tower are accurately calculated though computer program. The double lines on the same tower maybe use non-transposing span manner, few transposing span manner or two complete transposing span manners for reaching best power transmission quality and lowest power loss. These three manners have their strongpoint and shortcoming, and which transposing manner is selected should accord with the demand of engineering.
