AI Technical Summary
Traditional three-phase AC power supply systems lack the ability to assess the subtle power quality of the power grid in real time and from multiple dimensions when faced with complex and dynamic power supply and demand and load characteristics. This makes it impossible to achieve accurate dynamic optimization switching, resulting in insufficient power supply reliability and power quality.
By collecting the line voltage and load current signals of the three-phase power supply, the load type is identified, and the health evaluation value is determined based on the harmonic distortion rate and voltage fluctuation rate. The line with the best health evaluation value is selected as the selected line, and when the safety conditions are not met, a bridge circuit is used to synthesize two-phase voltage output to achieve dynamic optimization switching.
It enables multi-dimensional dynamic assessment of the health status of power lines, improves the system's adaptability to complex power grid environments and sensitive loads, ensures continuous and high-quality power supply to critical loads, maximizes the utilization of available power resources, and enhances power supply reliability and power quality.
