Abstract

In this paper, as the main contribution, three sensorless control structures are presented for the control of the grid-connected PMSG-based wind turbine (WT) employing boost converter and diode rectifier as the machine-side converter. Then, detailed control structures of the boost converter and grid-side converter at the three mentioned control strategies are extracted, and next, features of the abovementioned control strategies are investigated and compared against wind speed variation and grid voltage dip. The boost converter, in the first control strategy, controls the generator speed at the MPPT mode, and in the second control strategy, it regulates the PMSG active power to its set point value. Also, the boost converter, in the third control strategy, adjusts the voltage of the dc link capacitor to its set point value. In this paper, steady-state performance and transient/LVRT behavior of the WT system are examined for each mentioned control strategy in the Matlab-Simulink environment. It is shown that WT steady-state responses are relatively identical for all three control strategies. However, as an interesting result, at the fault conditions, the third control strategy has superior performance, and thus, the WT fault ride-through behavior enhances significantly with the third control structure without any hardware protection.
