Electromagnetic transient modeling and verification of DFIG unit and wind farm based on RTLAB

Electromagnetic transient modeling and verification of new energy unit and wind farm is becoming more and more important for new energy grid connection. This paper takes DFIG unit and DFIG wind farm as the research object. A new wind turbine generator modeling way of ‘ filed test - control hardware in the loop(CHIL) - dynamic link library(DLL) ’ is proposed, the two level time domain consistency verification proves the feasibility and accuracy of this modeling method. Furthermore, the multiplication equivalent model of wind farm is established, and the accuracy of wind farm model is verified.
