Reduction Of High-speed Electrified Railway Rail Potential Technical Measures

The paper firstly analysis the generating mechanism of rail potential, and give much simplified qualitative analysis for kinds of technical measures which are used to reduce the rail potential. Then it gives a brief illustration about the traction network mathematical model, the computer solution method, and the software development. Thereafter, it lists a lot of results which are combined with engineering practices. These results show the effect about kinds of technical measures that are used to reduce the rail potential. In the end, we can get conclusions from the academic analysis and the analysis about numerical computing results.The paper has finished the software TRANAS1.0 of analyzing traction network on the basis of establishing traction network mathematical model. Combined with the real instance of WU-GUANG passenger dedicated line, it utilized the software to carry out a mess of calculation, and get new cognitions about rail potential distributing rule and the effects from the primary electrical parameters of traction network.The paper has developed a suit of analyzing traction network software TRANAS1.0,a lot of calculation which is finished by the software shows that it can be used to choose the relational equipment parameter.
