Calculation and Application of Tunnel Traction Network Impedance Regarding Direct Power Supply Mode With Return Line Based on the Multi-conductor Loop Circuit System
摘要
Abstract
For the traction network impedance under direct power supply mode with return line in the tunnel section,a calculation method based on the multi-conductor loop system is proposed in this paper.In this method,all the actual loop circuits constituted by transmission and return conductors are considered,as well as the mutual influences of the self and mutual impedance of loop circuits.Each loop circuit's current distribution coefficient and traction network impedance based on established loop circuit impedance matrix is deduced.For the uniqueness of tunnel environment,Tylavsky formula is used to calculate the impedance of loop circuits containing the earth.Then,the actual applications about the multiple line regarding modes of separate,terminal parallel and full parallel are tried and analyzed.In the solutions of terminal parallel and full parallel modes,the constraint equations that satisfy the voltage drop relations are considered,and the iterative method is adopted to obtain the exact solution of impedance.Based on the experimental results at Yu-Li railway line in China,it can beshown that the proposed method can calculate the accurate traction network impedance at tunnel section.关键词
