摘　　要：由于现行方法在变速风力发电机组最大功率追踪模糊控制中效果不佳,发电机组输出电压超限值较高,而且输出功率偏差也较大,无法达到预期的控制效果,为此提出变速风力发电机组最大功率追踪模糊控制方法。描述风机能量捕获,确定模糊控制输入变量与输出变量,根据风机能量与发电机组输出功率关系识别误差,利用模糊控制理论对误差模糊化和反模糊化处理,得到模糊控制输出向量,实现变速风力发电机组最大功率追踪模糊控制。经试验证明,应用设计方法,发电机组输出电压超限值不超过0.1 V,功率偏差不超过0.1 W,能够有效追踪控制发电机组最大输出功率。Due to the poor performance of current methods in maximum power tracking fuzzy control for variable-speed wind turbines,the generator set’s output voltage exceeds the limit value,and the output power deviation is also relatively large,which cannot achieve the expected control effect.Therefore,a fuzzy control method for maximum power tracking of variable-speed wind turbines is proposed.This method describes the energy capture of wind turbines,determines the input and output variables for fuzzy control,identifies errors based on the relationship between wind turbine energy and generator output power,and uses fuzzy control theory to fuzzify and defuzzify the errors,obtain fuzzy control output vectors,and achieve maximum power tracking fuzzy control of variable speed wind turbine generators.Experimental results have shown that under the application of the design method,the generator set’s output voltage does not exceed 0.1 V,the power deviation does not exceed 0.1 W,and it can effectively track and control the maximum output power of the generator.
