弓网离线对高速列车牵引功率的影响研究

Study on Effect of Pantograph Losing Contact with Catenaries to Tractive Power of High Speed Train

随着高速列车速度的不断提高，伴随着的受电弓脱离接触网的故障也越来越频繁地发生，这将严重制约我国高铁的进一步发展。本文通过对弓网离线过程进行分析，利用PSCAD软件搭建了牵引供电系统一一动车组仿真模型。仿真结果表明，弓网离线会对高速列车牵引功率造成较大的影响。

With the speed of high speed train has continuously increased, the faults of pantogTaph losing contact with catenaries also have more and more frequently occurred ahmg with it, that will seriously restrict the further development of high speed rail in our country. By means of analyzing the process of pantograph losing contact with catenaries, the simulation model of the tractive power supply system and high speed motor train unit is constructed by using PSCAD software in this paper. The simulation result indicates that the fault of pantograph losing contact with catenaries may greatly influence the tractive power of high speed train.
