SVG, As the next generation product of SVC, STATCOM has superior performance in response speed, stability of voltage level, reducing system loss, increasing transmission capacity and improving transient voltage limit, reducing harmonics and decreasing occupation area etc. Since 2005, RXPE has begun to research and develop STATCOM with high-pressure large-capacity. In 2006, the STATCOM test platform has been completed successfully using DSP TMS320F2812. In 2007, the first STATCOM used for traction substation in China developed by RXPE.
