Abstract: |
In order to study the power quality of distributed generation system, a power quality online monitoring method is given for the DFIG. The PSCAD simulation software is used to build model, and power quality index curve of grid-connected doubly fed wind turbine is got and the simulation data is analyzed. The simulation results show that the method can accurately response the power quality of grid-connected doubly fed wind turbine and improve the accuracy of the simulation model. |
Key words: distributed generation power quality PSCAD DFIG accuracy |
