配电网单相接地故障消失后PT饱和过电流分析
Analysis of PT Saturation Over-Current After Single-Phase Ground Fault Disappears of Distribution Network
【摘要】 通过瞬时对称分量法分析了单相接地故障消失后,电压互感器电荷流动的暂态过程与引起过电流的影响因素,基于ATP-EMTP电磁暂态仿真软件对10kV配电网系统单相接地故障模型进行了仿真分析,并提出相应的抑制措施。
【Abstract】 The transient process of the voltage transformer charge flow and the factors caused overcurrent are analyzed by the instantaneous symmetric component method after single-phase ground fault disappears. A single-phase ground fault model of 10 kV distribution network system is anslysed based on the ATP-EMTP electromagnetic transient simulation software, and the corresponding suppression measures are put forward.
