| Summary: | A kind of control plan adaptive to serious asymmetry or ZVS of grid voltage is put forward, which can realize uninterrupted operation of the DFIG. It can be fit for small value symmetric drop and unbalanced three-phase control of the grid. The time sequence of whole uninterrupted operation is analyzed in detail, and based on the simulation research with PSIM, the experimental research is implemented for whole uninterrupted operation process through the Back-Back Test Bench and the prototype. The simulation and experiment results show that correctness and effectiveness of the control strategy are fully meet the connected-grid requirements of the power grid companies. |
