Shifted frequency analysis for EMTP simulation of power system dynamics
, 2009 Electromagnetic Transients Program (EMTP) simulators are being widely used in power system dynamics studies. However, their capability in real time simulation of power systems is compromised due to the small time step required resulting in slow ...

Gaoya dianqi, 2017 护套交叉互联双端接地电缆中,3段电缆长度不均等,或电缆排列方式不对称,均会导致金属护套中产生环流。文中分析了排管敷设的单回路交叉互联电缆金属护套感应电压相量和,采用EMTP模型仿真不同的电缆分段长度差下的金属护套环流,得到EMTP仿真数据样本,用来拟合金属护套环流估算公式,最后将拟合的估算公式计算值与EMTP仿真数据进行对比,检验了估算公式的适用性。此外,还分析了不同排列方式感应电压相量,提出并验证了在不等长分段电缆中,采用恰当的混合排列方式可以降低金属护套环流。
