基于风-网互补供电试验的风力机模拟研究

Wind Turbine Simulation Research based on the Test of Off-grid Wind Power-Grid Power Complementary Power Supply System

以抽油机离网风电-网电互补供电试验系统中的风力机为研究对象,根据风力机的运行特性,运用相似理论得到了模型试验中与风力机相似应满足的条件.计算了与某实际风力机在对应工况下相似的模型风力机的相关参数.在此基础上,建立一个由变频器拖动电机组成的试验模型来模拟风力机的运行,保证了试验模型具有实际意义.

Wind turbines used in the off-grid wind power-grid power complementary power supply system for pumping unit were selected as the research object. According to the operating characteristics of wind turbines, the pre-conditions of wind turbines similarity in the model test were obtained by using similarity theory. The parameters of the model wind turbine were calculated under the condition which was corresponding to a real wind turbine. On this basis, a test model composed of in- verter-driven motor for the simulation of wind turbine was established to guarantee that the test model was feasible and effec- tive.
