导线是飞机电源系统电能传输的主要载体。由于邻近效应，并排敷设相邻导线的电流有效值、频率等因素会影响导线阻抗值发生变化。为确定由于邻近效应引起的导线阻抗参数的变化，利用仿真软件Maxwell 2D/Simplorer 建立并排敷设导线仿真模型，分析在邻近导线电流有效值、频率变化时，被测导线电阻、电感的变化规律，并对引起阻抗变化的原因进行了分析。结果表明：由于邻近效应和趋肤效应，被测导线的电阻值会随邻近导线电流频率和有效值的增大而增大；被测导线的电感值随邻近导线电流有效值的增大而增大，随邻近导线电流频率的增大而减小；在相同频率下，并排敷设时被测导线电阻、电感比单根敷设时大。

The wire is the main carrier of aircraft power supply system power transmission. Due to the proximity effect, adjacent wires laying side by side ,current amplitude, frequency and so on ,will affect the impedance value.In order to determine the changes of impedance parameters caused by the proximity effect,using simulation software Maxwell 2D/Simplorer set up parallel wires simulation model,analyze the variation of the measured conductor resistance, inductance with the change of adjacent conductor current amplitude, frequency,and analyze the causes of impedence change.The results show that:Due to its proximity effect and skin effect,the measured wire resistance increases with the increasing of the adjacent conductor's current frequency and effective value;the measured wire inductance increases with the increasing of the adjacent conductor's current effective value, decreases with the increasing of the adjacent conductor’s current frequency;the measured wire,laying side by side,resistance and inductance is larger than the measured wire laying signal.
