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。

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。

Modelling of doubly fed induction generator by using of ATP-EMTP program
This paper presents the simulation results of a grid-connected windmill driven doubly fed induction generator (DFIG) together with some machine performance results. The model was prepared by using of widely known ATP-EMTP program. The construction of a dynamic model of a DFIG is similar to a wound rotor induction machine.
