Through the method of experiment analysis to a 400W direct drive permanent magnet wind turbine prototype in this paper, as to the permanent magnet wind generator output voltage stability, taking the changing rate of voltage(voltage regulation) as stability parameters, we sample different speeds, different loads and different tip-speed ratios of the output voltage by two kinds of operating mode. One...
According to wind resource data in different parts, the characteristic wind speeds of wind turbine were calculated. From low cost considerations, the characteristic wind speeds of wind turbine were optimized, the diameters of wind wheel were shortened and the difficulty of technology was reduced, in order to design the wind turbine. Finally the thesis contrasted and validated by Experimental analysis...
In this paper, the wind atlas was presented using the WAsP software based on the wind resource data of four regions in Inner Mongolia during 1998-2008, which were provided by the China meteorological date sharing service system. The scale parameter A and the shape parameter k of Weibull probability density distribution function could be calculated. Furthermore, the cut-in wind speed and rated wind...
As far as the currently used lead-acid battery has poor abilities of self-resistance to overcharge and over-discharge, it is unsuitable for a dedicated storage device of wind turbine. This paper proposed a control strategy of storing and releasing energy about off-grid wind turbine by analyzing and studying the ideal characteristic curve of charging voltage and current of lead-acid battery. The strategy...
