摘要
Abstract
Power transmission lines of high speed railway usually adopt full cable laying, and the traction power supply system will generate induced voltage when the working current acts on the metal protective layer of power cable. With the increase of locomotive operating speed, it is urgent to improve the working current of traction power supply system when the induced voltage of metal layer of power cable may endanger the safety of person-nel and equipment. In this paper, the influence of traction power supply on the induced voltage of power cable was analyzed. Besides, a simulation model combining the traction power supply system and power cable was es-tablished by using unified chain circuit model. Then, the induced voltage of power cable under different working currents of traction power supply system was simulated and calculated, and the calculation results were consis-tent with the theory. Research results show that the increase of working current of traction power supply system has little influence on the induced voltage of power cable, and the simulation model and data can provide rail-way electric power professionals with reference for design and construction.关键词
