Abstract: |
A voltage compensation method of an electrical energy quality compensator in series is realized by rotating the phase angle of a loaded voltage as follows: 1. to determine the rotating range of the angle of the load voltage refernece vector according to the system fault voltage and the voltage compensation limit. 2. to calculate the energy optimization angle by using the load power factor and system fault voltage plus sequence components. 3. to combine the optimized angle determined in 2 and the angle rotating range determined in 1 to select the rotating angle of load voltage reference vector to enlarge the voltage compensation range to reduce the energy insertion. |
