Abstract
Along with environmental consciousness enhancement, conventional energy depletion, wind energy exploitation is expanding gradually due to the renewable merit, clean without any pollution and vast reserve features. Therefore, wind power generation (WPG) system equipped with Doubly Fed Induction Generators is emerging as mushroom. Larger rated capacity of power unit, the higher tower and the variable pitch are the main scope in WPG system. However, latent trouble will bring about likewise. If a fault occurred, it will be catastrophic for WPG system. Consequently, the technology of fault detection will play a more important role in WPG system. Based on the present status, a novel method is proposed in this paper after summarizing and analyzing the lack of previous methods. Then an example for detecting the inverter fault is studied using PSCAD software. Results indicated that the proposed method is effective and feasible.
