| 摘 要： | 从电力电缆传输中存在的谐波电流出发,对电缆谐波阻抗模型的主要参数进行了估算,建立了电缆供电的等效电路和等效电路参数计算,并按照电缆供电中存在的谐波电流范围以及漏电容可能的变化范围,对谐波漏电流进行了Matlab仿真。仿真结果表明,在系统参数和电缆漏电容巧合的情况下,流过电缆漏电容的谐波电流被放大,高次谐波电流致使电缆绝缘介质发热并烧焦起火。

| Abstract: | Focuses on the two aspects that the analysis of the cable leakage capacitance and harmonic current amplified from the point where there is harmonic current heavily existed in the power cable transmission system.The main parameters in the cable harmonic impedance model are estimated.The equivalent circuit based on the cable power supplying is established as well as parameters included in the equivalent circuit are estimated.Finally,the harmonic leakage current is simulated by Matlab based on harmonic current... |
