Working principlerr
It consists of a B-based voltage source inverter connected to a reactor, a DC energy storage unit and a digital control provider. The basic principle is to use shut-off high-power power electronic devices (such as B) to form a self-switching bridge circuit, which is connected in parallel to the power grid through a reactor, and the amplitude and phase of the AC side output voltage of the bridge circuit are appropriately adjusted, or directly controlled. Its AC side current can enable the circuit to absorb or generate reactive current that meets the requirements, achieving the purpose of dynamic reactive power compensation.
