Abstract:This paper briefly introduces the high power density modular static var generator SVG power cabinet products. In view of the present domestic and foreign manufacturers of SVG power cabinet. Generally there are complex wiring and so on many defects. Developed a compact structure, Convenient power unit cabinet put oneself in another's position between the attachment, Capacity is advantageous for the extension of static reactive power generator based on high power density modular power cabinet.For high voltage large capacity of reactive power compensation device development in our country has opened up a new road, For high voltage large capacity of power electronic equipment research and development in China provides a valuable experience.
