[0026] The present invention will be described in detail below with reference to the drawings and specific embodiments.
[0027] Implementation example figure 1 As shown, a flexible reactive power compensation device is connected to the AC power grid 4 and includes a reactive power acquisition module 1, a control module 2 and an inverter module 3. The reactive power acquisition module 1 is set on the load side of the AC power grid 5 and the output terminal of the inverter module 3. The control module 2 is connected to the reactive power acquisition module 1 and the inverter module 3, respectively. The output terminal of the inverter module 3 is connected to the AC power grid 4 through a reactor 6.
[0028] The reactive power acquisition module generates sampled digital signals through current transformers and voltage transformers, generates corresponding reactive power through calculations, and finally inputs them to the control module for processing. The control module is realize...
