Abstract
In this paper, the active front-end (AFE) converter topology for the total harmonic distortion (THD) reduction in a wind energy system (WES) is used. A higher THD results in serious pulsations in the wind turbine (WT) output power and several power losses at the WES. The AFE converter topology improves the capability, efficiency, and reliability in the energy conversion devices; by modifying a conventional back-to-back converter, from using a single voltage source converter (VSC) to use pVSC connected in parallel, the AFE converter is generated. The THD reduction is achieved by applying a different phase shift angle at the carrier of digital sinusoidal pulse width modulation (DSPWM) switching signals of each VSC. To verify the functionality of the proposed methodology, the WES simulation in Matlab-Simulink® (Matlab r2015b, Mathworks, Natick, MA, USA) is analyzed, and the experimental laboratory tests using the concept of rapid control prototyping (RCP) and the real-time simulator Opal-RT Technologies (Montreal, QC, Canada) is achieved. The obtained results show a type-4 WT with a total output power of 6 MVA, generating a THD reduction up to 5.5 times of the total WES current output by Fourier series expansion.
Highlights
Nowadays, the number of wind energy systems (WES) has increased dramatically, as evidence of this; in 2013, WES were installed in more than 80 countries, generating a power of 240 GW [1], in 2014, the generation reached a capacity of 369.9 GW [2], in 2015, a production of 432.883 GW was generated [3]
MSC and GSC are connected to wind turbine (WT)-PMSG and the AC grid through RL filters, both converters are formed by three voltage source converter (VSC) connected in parallel and each one is designed to possess a power and voltage of 2 MVA and 2.5 kV, respectively
