Abstract: SVG plays a crucial role in the operation of new energy stations, not only regulating the reactive power of new energy stations and improving their power factor, and Moderate regulation and control of the voltage at new energy stations can effectively suppress voltage fluctuations, voltage flicker, and current harmonics. This article takes the SVG grid connection performance test of a certain station as an example to introduce the test requirements and contents, and elaborates on the test results. Typical problems in the test process are analyzed. This article has certain guiding significance for the development of new energy SVG.
