Abstract
Since the last decade, the number of grid-connected wind farms (WFs) has increased. Conventionally, a horizontal axis wind turbine (HAWT) with single rotor is widely used in WF applications, and the blade root region (adjacent to the hub) of a HAWT suffers from aerodynamic incompetence due to various non-aerodynamic limitations. WF performance is also significantly reduced due to aerodynamic interactions between turbines. To address this problem, a dual rotor wind turbine (DRWT) for permanent magnet synchronous generator (PMSG) and squirrel cage induction generator (SCIG) is built in this paper to improve the WF's performance. The DRWT is made up of two types of rotors: main and secondary. In comparison to HAWT, the proposed DRWT mechanism will extract more mechanical resources. When the wind speed is poor, the overall architecture will function properly. The PSCAD/EMTDC software is used to build and evaluate a hybrid power system that includes a robust DRWT-PMSG, DRWT- SCIG model, and a traditional power plant. According to simulation results, the built DRWT can extract more power than a traditional single rotor HAWT.
