Model prediction control method for voltage source-type rectifier when grid voltage is unbalanced |
| abstract |
A model prediction control method for a voltage source-type rectifier when the voltage of a grid is unbalanced, comprising: (1) three-phase grid voltage and current are converted via abc/αβ coordinates into grid voltage and current in a two-phase static coordinate system; (2) a positive and negative sequence coordinate separation is performed on the grid voltage in the two-phase static coordinate system to acquire a positive sequence voltage and negative sequence voltage of the grid; (3) an active power reference value is calculated; (4) a current reference value of the rectifier in the two-phase static coordinate system is calculated; and, (5) a model prediction current control is performed to select the optimal switch state. The method, while ensuring rapid and accurate tracking of a current in two phases of static coordinates, effectively eliminates voltage fluctuations at an alternating current side, and improves the quality of electric power of the system. |
