The forces on a turbine at extreme wind conditions when the turbine is parked is one of the most important design cases for the survivability of a turbine. In this work, the forces on a blade and its support arms have been measured on a 12 kW straight-bladed vertical axis wind turbine at an open site. Two cases are tested: one during electrical braking of the turbine, which allows it to rotate ...

in this research paper, a 10 minute period measured wind speed data at 10 m, 30 m, and 40 m heights are presented for one of the major provinces of iran. four stations in khuzestan- abadan, hosseyneh, mahshahr, and shushtar- are analyzed to determine the potential of wind power generation in this province. from the primary evaluation and by determining mean wind speed and also the weibull funct...

Wind turbines are increasingly becoming significant components of power systems. To evaluate competing wind energy conversion technologies, a real-time Wind Turbine Emulator, which emulates the dynamic torque produced by an actual turbine has been developed. This is necessary since the real world performance of a wind turbine, subjected to variable wind conditions is more difficult to evaluate ...

Based on the analysis of operation characteristics fault direct-drive permanent magnet wind turbine and existing protection strategies, in order to improve low-voltage capability turbine, a new coordinated control strategy for crossing is proposed this paper, which includes DC brake system unloading circuit, double second-order generalized integral phase-locked control, extracting positive nega...

This paper presents the dynamic model and Detail Analysis of a Wind energy conversion system equipped with permanent magnet synchronous generator (PMSG). There are different types of synchronous generators, but the PMSG is chosen, in order to obtain its dynamic model. It offers better performance due to higher efficiency and less maintenance since it does not have rotor current and can be used ...

Abstract The drivetrain as an important part of wind turbines needs to be improved in order deal with today’s high development and cost pressure. One step towards enhanced drivetrains is identify the most suitable concept for a targeted onshore application early design stage. With this purpose, holistic lifecycle system evaluation approach relying on minimum input information presented. In domi...

This paper presents the design and an analysis of a surface PM vernier generator (SPMVG) for MW-scale direct-drive (DD) wind turbine application. An SPMVG has advantage higher torque density; however, especially at power ratings with increased electrical loadings, factor worsens there are some serious concerns including magnetic saturation cores demagnetization. These issues directly related to...
