By analyzing a variety of capacitor bank switching circuits, a new high voltage reactive power compensation device was developed based on improvement of part circuits. The new device has some distinct advantages, such as quick tracking of change of capacitive reactive power, current impact can be avoided effectively, and retriggering can be effectively prevented when switching off. Working characteristics are like as thyristor, but using cost and energy consumption are lower than thyristor.
