Popis: | This paper presents a wind power system using a Per manent Magnet Synchronous Machine (PMSM). The whole system consists of a wind turbine, a permanent magnet synchronous machin e, a three phase diode rectifier, a boost converter , a transformer-less step down circuit, an H-bridge inverter and a T-LCL filter. T he 3-phase AC output from the PMSM is sent to the 3 -phase diode rectifier for conversion to DC and a boost regulator is used to s tep-up this DC voltage to the desired level. This s tep-upped DC voltage is then converted into AC output by the H-Bridge inverter. The switching technique of the proposed inverter co nsists of a combination of Sinusoidal Pulse Width Modulation (SPWM) and a squa re wave along with grid synchronization conditions. As the suggested method is entirely transformer-less, it significantly reduces Total Harmonic Distortion (THD) to less than 0. 1% and minimizes its size. The TLCL Immittance Converter not only reduces the harmo nics of the inverter output but also provides a nea rly constant output current thereby stabilizing the system. The system setup an d the simulation results were obtained using the PS IM software. |
