【摘要】 线路电感计算对于网络分析至关重要,针对同轴电缆和双导线回路两种基本线路形式,分析电感传统计算方法的有效性,并通过有限元数值法计算电感值。对比结果表明,随着双导线回路导线间距的减小,传统方法计算误差逐渐增大,分析了误差产生的原因。在此基础上,提出了在传统计算公式中加入修正因子来减小计算误差的方法,并给出了修正因子表达式。研究成果可为电力电子网络计算提供更准确的参数计算理论与方法。更多还原

【Abstract】 This paper focuses on the calculation of circuit inductance. The validity of the traditional calculation method is analyzed in the two basic forms of the coaxial cable and the double conductor circuit,and the inductance values are calculated by the Finite Element Analysis( FEA). The comparison results show that the error of the traditional method increases gradually with the decrease of the distance between two conductors,and the cause of the error is analyzed. On the basis of this,a correction factor is proposed to be added into the current calculating formula to reduce error,and the correction factor expression is given. The research result provides a more accurate parameter calculation theory and method for power network parameter calculation.更多还原
