| Abstract: | Based on the theory of uniform transmission line and four-terminal net circuit, this paper presents a simulating model of ZPW-2000A jointless track circuit. A kind of numerical algorithm of shunt current is established with MATLAB. The Simulating result is compared with the measured data, which proves that the simulating model and algorithm is correct and practical. |
