Simulation of Current Distribution in Parallel Single-Core Cables Based on Finite Element Method
This paper has presented the current distribution analysis associated with parallel single-core cables.As the current distribution in a multi-phase cable distribution system is determined by the cable impedance,the FEM algorithm of the cable impedance matrix is introduced.Further,by using Maxwell-15,a 2-D model of single-core cables was established.The impedance matrix and current distribution under horizontal,double-row and triangle laying arrangement were then calculated.It is concluded that cables under triangle arrangement have the most balanced mutual inductance parameters,and the slightest electromagnetic coupling effects.Meanwhile,the current unbalanced degree of the triangle laying cables is also the least.The triangle laying arrangement is recommended in parallel single-core cable installations.
