Abstract

Negative sequence current and three phase voltage balance are the most important power quality problems in the traction power supply system of high speed railway Compared with ordinal electric locality, the traction power required by high speed trains is significantly increased, and the negative sequence current injected into the power system is significantly increased At the same time, the high speed train has the characteristics of high load rate and long power receiving time, which makes the negative sequence current generated by the high speed railway has the characteristics of long duration This paper introduces the power characteristics and load characteristics of high speed rail traction power supply system, studies the calculation of its negative sequence current and three phase voltage balance, and puts forward a new three phase voltage balance compensation device and its matching algorithm, Which is suitable for the treatment of negative sequence current and three phase voltage balance in high speed rail traction power supply system Finally, the expected effect is verified by simulation, which provides its feasibility and correctness.
