摘要
Abstract
In response to the problems brought by the traction power supply system to the high-voltage power grid,such as negative-sequence,harmonics and reactive power,a novel integrated compensation system for electrified railway pow-er quality is proposed based on Y/>▽balanced transformer.The system makes full use of the trian gular winding tap on the secondary side of the Y/>▽balanced transformer,and directly connects the traditional back-to-back railway power flow controller with the tap.On the one hand,a single-phase coupling transformer can be saved,which makes the sys-tem have an obvious advantage in the cost of investment;on the other hand,the integration degree of the whole system can be improved,thus reducing the cover area of the equipment.In this paper,the structure and characteristics of the system are introduced firstly,and the compensation principle is discussed in detail.Then,a method is given to detect and control the system.Finally,a system simulation model is built by using Matlab/Simulink.Simulation result verifies the compensation performance of the system from the aspects of negative-sequence,harmonics and reactive power.关键词
