摘　　要：利用多导体传输线模型,建立变电站内多芯屏蔽控制电缆的串扰计算模型。针对实际多芯屏蔽电缆的绞合结构,提出了对多芯屏蔽电缆传输线模型的分布电容及电感参数的修正方法。对KVVRP-22型19芯屏蔽电缆进行了理论计算与试验测量,证明了方法的有效性,为准确分析多芯屏蔽电缆中电磁干扰的传播规律提供了工程计算方法。This paper has established the multi-conductor transmission lines of shielded cable in the substation to calculate crosstalk between core wires. For the twisted structure of the core wires,this paper has proposed a method to correct the distributed capacitance and inductance parameters of the multi-conductor transmission lines. The crosstalk between the core wires of KVVRP-22 19-core shielded cable were calculated by this method. It illustrated the effectiveness of this method to compare computed results with experimental results. This paper provides a more accurate engineering method to calculate the crosstalk between the core wires of shielded cable in the substation.
