摘　　要：近年来铁道建设发展较快,低阻抗、高过载能力的V/V牵引变压器也得到快速推广。电气化铁道电力机车属于单相负荷,具有冲击和非线性的特性,对供电电能质量影响较大,用户投诉时有发生,已经引起电力部门、铁道部门的高度重视。通过对V/V接线牵引变电所接入电力系统的电能质量分和治理方法研究,有助于提出经济合理的治理方案,改善对供电系统电能质量的影响。With the rapid development of the railway construction, V/V wiring traction transformer with low impedance and high overload capacity is widely used in recent years. The electric traction locomotive of the electric railway is a single-phase load, which has the characteristics of shock and nonlinearity. The electric locomotive has great influence on power quality. Complaints caused by power quality have occurred frequently, which have attracted great attention in electric power company and railway department. By studying the simulation on the influence and the control of the V/V wiring traction substation, the purpose is to put forward the economic and reasonable treatment plan and improve the power quality of the power supply system.
