This paper presents a control method for output power smoothing of a wind energy conversion system (WECS) with a permanent magnet synchronous generator (PMSG) using the inertia of wind turbine and pitch control. The WECS used in this paper adopts an AC-DC-AC method with voltage-source converters (VSC). The generator-side converter controls the generator torque of the PMSG, while the grid-side inverter...
A small scale wind energy conversion system has tremendous diversity of use and operating conditions, and consequently is evolving rapidly along with the large scale wind energy conversion system for generation of electricity in either stand-alone or grid connected applications. In recent years, the grid connected small wind turbine industry is primarily dominated by the Permanent Magnet Generator...
Large-scale permanent magnet generators with full power electronic converters are of increasing interest to many wind turbine manufacturers. These systems offer an efficient and reliable solution for offshore and low wind sites. However, the advantages of these generators necessitate a system design approach when selecting a power electronic drive and designing to meet the toughest grid code elements...
This paper encompasses the study of modelling and design of WECS, using a wind turbine with known dynamic characteristics and a permanent magnet synchronous generator driven by a back to back power converter topology. The dynamic modeling allows to know the response of the turbine generator system in the whole range of operation. In this study, it is proposed a variable structure control scheme with...
This paper proposes a control strategy for variable speed wind energy conversion system (WECS), incorporating maximum power point tracking (MPPT) algorithm, using direct driven permanent magnet synchronous generator (PMSG). The generator is operated in the speed control mode below the base speed by controlling the terminal voltage using three phase front-end active-rectifier feeding power to the DC...
