| 摘 要： | 电网的经济技术指标是选择最优电压组合的重要依据。因此，如何科学地计算出不同电压组合的待建农村电网的相关经济技术指标，就成为研究此类问题的关键所在。提出一个基于统计数据，辅以《农村电力网规划设计导则》的电网模型来研究经济技术指标。该模型是出线、变电站容量和导线截面都随负荷密度变化而变化的动态模型。该方法避免了采用固定值建立适应性差的模型，使模型更加合理、更加符合实际情况。实例证明该方法是有效和可行的。

| Abstract: | The economically technical index is an important factor for choosing the best voltage level for the power network.The calculation of the correlation network index is the key.A mathematical network model is built based on the statistic data and the 'plan design guide for the rural electric power network'.The economically technical index can be calculated through the model.The best voltage configuration can be chosen according to the result.Transformer's out lines and capacitance change along with the charge density,so does the section of the lines.Therefore,the dynamic model is more scientific and reasonable than others.The example can prove this method is effective and feasible. |
