| 摘 要： | 为应对大型能源基地输电走廊紧张的问题，出现了一些相对复杂的发电厂、变电站接入方式，导致传统的分析经验难以适用，以一种利用同塔双回输电线路将发电厂密集接入电网的设计方式为场景，针对该方式下输电线路的感应特征来自于线路中不同同塔分段耦合叠加的问题，在 ＥＭＴＰ程序中建立了仿真模型，通过计算线路整段及各分段的感应电压和感应电流，分析了这种接入方式下输电线路的感应特征。

| Abstract: | Based on the design method of intensively connecting power plants into the power gridusing twin transmission lines of the same tower, the simulation model is established in the EMTPprogram. By calculating the inductive voltage and current of the whole lines and segments of the line,the inductive characteristics of the transmission lines under the access mode are analyzed. |
