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.
Taking the wind turbine in off-grid wind power-grid complementary power supply test system of pumping unit as the research object, according to the operating characteristics of the wind turbine, the similar conditions to be satisfied in the model test with the wind turbine are obtained by the similarity theory, The actual parameters of the actual wind turbine in the corresponding operating conditions of the model wind turbine.On this basis, to establish a test model consisting of inverter drag motor to simulate the operation of the wind turbine to ensure that the experimental model is of practical significance.
