چکیده
Energy is the foundation of economic development and technological development. Facing present situation non-renewable energy decline, wind power generation has been developed rapidly. However, problem unstable output voltage due to speed needs be solved, traditional solutions cannot make generated electric meet national standards for grid-connected off-grid operation. In this paper, by turbine rectified bridge rectifier circuit using large capacity capacitor filtering generate DC with flat waveform. Then, SPWM inversion technology, normal rotation wave same frequency as grid used modulation according required amplitude, triangle appropriate duty ratio calculated smoothing control theory carrier wave. Subsequently, accurate carried out operation through self-aligning device. Finally, help MATLAB simulation platform, simulated work under different conditions, whether meets judged, which further determines reliability authenticity theory.

In this paper a compensation strategy based on a particular CUPS device, the Unified Power Quality Compensator (UPQC) has been proposed. A customized internal control scheme of the UPQC device was developed to regulate the voltage in the WF terminals, and to mitigate voltage fluctuations at grid side. The voltage regulation at WF terminal is conducted using the UPQC series converter, by voltage...

Wind Farms (WF) employing squirrel cage induction generator (SCIG) is directly connected to the grid, it represent a large percentage of the wind energy conversion systems around the world. In facilities with moderated power generation, the WF are connected through Medium Voltage (MV) distribution headlines. A situation commonly found in such scheme is that the power generated is similar to the...

This paper proposes a new method for direct control of active power and stator flux of permanent magnet synchronous generator (PMSG) used in the wind power generation system. Active power and stator flux are controlled by the proposed discrete time algorithm. Despite the commonly used vector control methods, there is no need for inner current control loops. To decrease the errors between refere...
