| description | The invention relates to a virtual reactive power compensator. A reactive power compensation capacitor C3 is connected with a power grid through two low-voltage large-current MOS transistor switchingcircuits connected in parallel, wherein one circuit charges the C3, and the other circuit performs discharging on the C3. When the C3 is charged, and the inductive reactive current and various kinds of non-linear current of the power grid can be absorbed. When the C3 carries out discharge, the charges of the C3 are injected into the power grid in the form of sine wave current according to the magnitude of charging current, the frequency and phase angle of the sine wave current being the same as the frequency and phase angle of the voltage of the power grid; the power grid, replacing the C3, stores the charges; and therefore, the capacity of the C3 becomes virtual capacity, and the reactive current of the power grid can be absorbed infinitely and converted into active current, and the active current is returned to |
