摘　　要：导线经济截面传统上根据导线经济电流密度进行选取,是电网规划设计中的重要内容。而现行的国家颁布的经济电流密度表已经不符合现阶段的需求。通过建立导体总成本的数学模型,进行论证,分析计算得到了新的合乎目前实际的经济电流密度值,据此进行选取导线经济截面,可以提高经济效益。Conventionally, economical conductor section determination, which is an important content of grid planning, is based on conductor economical current density. However, the established national economical current density table does not keep up with current needs. Through establishing total conductor cost mathematic model and calculation, new and practical economical current density values can be obtained. Economical conductor section can be selected using these values, resulting better economic benefits.

关 键 词：经济截面 经济电流密度 导线总成本
