Example Embodiment
[0057] figure 1 Inside the dashed box is a grid power oscillation suppressor 8 based on photovoltaic cells, which consists of photovoltaic panels 1, photovoltaic inverters 2, filters 3, grid-connected transformers 4, controllers 5, voltage transformers 6, and current transformers 7. and other components, the following describes each component in detail:
[0058] 1 is a photovoltaic panel, which can be composed of multiple photovoltaic cells, converts solar energy into electrical energy, and outputs DC voltage;
[0059] 2 is a photovoltaic inverter, which converts direct current into alternating current and transmits it to the power grid. The inverter is composed of voltage source type fast turn-off devices, which have fast active and reactive power regulation capabilities;
[0060] 3 is a filter, which filters out the high-frequency harmonics output by the photovoltaic inverter, so that the voltage waveform output by the inverter is basically consistent with the grid voltage ...
