基于EMTP-ATP的330 kV全线同塔双回线路感应电压及感应电流计算建模

Computing Modeling of Induced Voltage and Induced Current for 330 kV Double-Circuit Lines on the Same Tower Based on EMTP-ATP

由于同塔双回线路回路间距减小,停电线路与运行线路间的电磁耦合和静电耦合大大增强,在停电线路上产生较高的感应电流和感应电压。以某全线同塔双回330kV线路为例,基于EMTP搭建了计算模型,分析并计算了静电感应电压、静电感应电流、电磁感应电压、电磁感应电流,为地区电网中330kV同塔双线路的设计、规划以及运行提供了参照依据。

Due to the reduction of loop spacing of double-circuit lines on the same tower, the electromagnetic coupling and electrostatic coupling between the outage lines and the operation lines are greatly enhanced, resulting in higher induced current and induced voltage on the outage lines. Taking 330 kV double-circuit lines on the same tower as an example, a calculation model is established based on EMTP. The electrostatic induced voltage, electrostatic induced current, electromagnetic induced voltage and electromagnetic induced current are analyzed and calculated, which provides a reference for the design, planning and operation of 330 kV double-circuit lines on the same tower in the regional power grid.
