SVG Admittance Testing System OPAL-RT TECHNOLOGIES 1 1. Challenge With the rapid development of modern grid, the integration of new energies, the operation of AC/DC hybrid power grid, and the widely use of non-linear loads and impact loads like high-voltage large-capacity power electric devices, the dynamic reactive problem of power grid is becoming more and more obvious. SVG (STATCOM: Static Synchronous Compensator) has recently been widely used, since it has the advantages of high-speed dynamic response and the excellent ability of voltage flicker suppression, etc. However, there is no effective means or system of testing for SVG devices produced by different manufacturers. To solve the problem, Shanghai KELIANG Information Tech. &
