适用于电气化铁道的静止无功发生器SVG的研究

Research of the Static Var Generator(SVG) Suitable for Electrified Railway

静止无功发生器SVG(Static Var Generator)相对于传统的无功补偿装置具有明显的优越性。现根据电气化铁道供电的实际情况,从SVG装置的主电路结构、电流检测方法、控制系统等各个方面进行研究,设计出适合于电气化铁道的SVG装置,并进行了仿真验证。

Compared with traditional reactive power compensation device, static var generator （SVG） has obvious advantages. This paper studies the main circuit structure, the current detection methods, control system and other aspects of the SVG device according to the actual situation of the electrified railway power supply, designs SVG device suitable for electrified railway, and makes simulation.
