Abstract The installation environment of wind turbine was tested by using lidar wind meter, and the power test platform of small wind generator was designed and built for field test. The collected wind environment data were analyzed and the wind environment of the test site was evaluated. By monitoring the operating state of off-grid wind power generator in the field, the actual output power, and the wind speed and wind direction data were measured synchronously, and the actual wind speed-power curve of wind turbine was fitted by the least square method. The results show that the laser radar wind meter can provide a selection basis for the installation of the wind turbine, and the prediction of the output power of the wind turbine in the high wind speed region by using the theoretical curve of wind speed and po-wer will cause great errors. Using lidar to monitor the wind environment can select the direction and height of wind turbine installation. It is more accurate to predict the output power of wind turbine by using the sixth degree polynomial curve fitted by the least square method. The actual measurement data obtained in this paper can provide a reference for the field test of wind turbine.
