【 摘 要 】

Reasonable assessment of wind farm operation provides reliable wind farm operation information for dispatching, such as theoretical output, and optimization of wind farm control operation is of great significance in improving the full absorption of new energy in the regional power grid. Taking wind farms of Yunnan in the plateau mountain and three-dimensional climate conditions as objects, the theoretical output model of wind power fan is based on the precision of wind speed data. Wind farm of plateau section located in the ridge and wind resources significantly with altitude change greatly, for this situation, it is not representative and scientific to evaluate the wind speed at the wind turbine position by using wind tower, then it directly affects the accuracy of wind turbines theoretical output evaluation. For this reason, first of all, a laser radar device is used to measure the wind speed of wind turbines engine room accurately. Secondly, taking the wind speed data of lidar as reference point, the CFD simulation is used to calculate the wind speed of wind turbines in the wind farm. Finally, the calculation of wind speed and the actual output power of wind turbine which is collected from SCADA fitting, the fitting power curve is compared with the static power curve provided by the manufacturer, and the feasibility of the method is verified. The proposed strategy is applied to a wind farms in Yunnan province, the simulation results show that CFD simulation and calculation of full field wind turbine output based on the data of laser lidar wind measurement instrument, it is feasible and excellent.
