摘要
经济电流密度是选择导线截面时的一项重要参考指标。该指标与线路造价、电价等因素密切相关。由于我国幅员辽阔,各地区能源生产消费特点、工程建设条件等因素存在较大的差异,有必要根据各地区自身特点研究相应的经济电流密度。笔者基于总拥有费用法,提出适合500 kV输电线路的经济电流密度数学模型,根据广东电网的特点,通过分析计算,得到了符合广东实际的经济电流密度,对广东境内的电网规划设计有较大的参考价值。
The economic current density is an important index when choosing the section of conductor.The index is closely related to the line cost,price and other factors.Because our country has vast area and there is a big difference in characteristics of regional energy production and consumption,construction conditions and other factors,the study of economic current density according to its own characteristics of the various regions turns out to be necessary.Based on the total cost of ownership,500kV transmission line for the economic model of current density is proposed in this article.According to the characteristics of Guangdong Power Grid,the feasible economic current density of Guangdong is found.The result is referential for planning and design of Guangdong Power Grid.
