Digital simulation of the MFTF power supply system using EMTP

, 1979
The power supply system for MFTF will consist of twenty-four sets of accel, arc, and filament power supplies. The system will be fed from a common source and split into sets of two for the accel supplies and sets of four for the arc and filament supplies.

超高压变电站雷电过电压现场实测与仿真计算

Dianci bileiqi, 2008
简述了电力系统过电压问题的研究方法:TNA具有直观性,实测具有真实性,仿真计算具有灵活性。为研究某超高压变电站雷电过电压与绝缘配合问题,用低压冲击波进行了时间比例尺、阻抗比例尺均为1的现场试验,且用ATP-EMTP仿真计算了设备上的雷电侵入波过电压。试验结果表明,一线一变、一线两变两种运行方式下,降压实测与ATP-EMTP仿真计算结果基本一致,说明将实测与计算结合起来是一种分析此类问题很好的方法。
