An Investigation of Power Performance of Small ...

In this study the power performance of two small grid connected wind turbines have been investigated. The objective was to study impact of load power factor on the wind turbine power curve. Two small wind turbines were tested in a number of load conditions and test data were collected for about two months. A set of resistors, inductors and capacitors were used as load in addition to grid connection. The every second test data was collected for at least two days in each load condition. Data was analyzed for active power, power factor and reactive power. Wind turbines power curves are plotted with load and without any load connected between the wind turbine and the grid. Results indicate that type of load does not significantly effects the power curve of a small wind turbine. It was also observed that above 200W power factor of small grid connected wind turbine was also constant.
