阐述针对架空线与电缆的暂态特性差异大,导致混合配网的雷击暂态过电压波特性趋于复杂的特点,提出搭建PSCAD/EMTDC计算模型,对混合配网雷击暂态过电压波的时域和时频域特性进行分析.
Analysis of Transient Overvoltage Waves Characteristic Caused by Lightning Strikes in Hybrid Distribution Networks
This paper expounds the significant differences in transient characteristics between overhead lines and cables,which lead to the complexity of transient overvoltage waves caused by lightning strikes in hybrid distribution networks.A PSCAD/EMTDC calculation model is proposed to analyze the time-domain and time-frequency domain characteristics of transient overvoltage waves caused by lightning strikes in hybrid distribution networks.
