Modelación de un cañón electromagnético mediante ATP-EMTP y ATPDraw

open access: yes
Este trabajo presenta un modelo de cañón electromagnético desarrollado en la herramienta ATP-EMTP y su entorno gráfico ATPDraw. El diseño se basa en varias etapas de bobinas circulares a través de las cuales se desplaza una armadura metálica cilíndrica.

35kV变电站电缆护套过电压保护研究

open access: yesDianci bileiqi, 2008
分析了一起雷电波入侵电缆造成护套保护器损坏的原因,运用ATP-EMTP搭建了雷电侵入波作用下架空线与电缆相连(包括母线侧的各种电器设备)的简化模型。通过仿真计算,电缆护层末端接地和首端直接接地两种接地形式下的过电压分别为10kV和9.3kV,选出适合的国产保护器型号为Y5WC-5/13.5。

一种输电系统接地故障定位的新方法

open access: yesDianci bileiqi, 2016
提出了一种利用接地故障产生的高频暂态电压进行故障定位的方法,该方法仅利用初次到达测量端的高频暂态波,而完全不需要反射波,从而可以有效避免故障点和对端母线的反射波之间的区别问题。大量的ATP/EMTP仿真分析验证表明,该方案精度较高,故障定位误差在线路总长度的1%之内。

Modelación de sistemas eólicos (WECS) utilizando la herramienta ATP-EMTP y MODELS

open access: yes, 2023
In this research we will make the modeling of a wind power system by using the ATPDraw platform. Starting from the modeling of the wind turbine, AC/DC-DC/AC converters until to reach to the power grid. A DTC controller is used for the generation part and a DPC control for the load.
