Embodiment Construction
[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0038] like figure 1 As shown in the figure, the flexible grounding device is composed of a DC voltage source, a single-phase inverter, an LC filter and an isolation transformer. The inverter is composed of four IGBT tubes. It is connected to the neutral point of the distribution network, and the neutral point is led out by the isolation transformer. Among them, U O , I O are the output voltage of the flexible power supply and the current injected into the grid (boost to low voltage side), respectively, Inject the current of the neutral point for the flexible power supply (boost to the high voltage side), is the electromotive force of the power distribution network, is the neutral point voltage; L O , C O Output filter inductor and capacitor for single-phase inverter, C A , C B , C C is the capacitance of the distribution network to ground, r e ...
