摘　　要：文章基于低水头流水发电的工况特点和并网原理,建立了永磁同步发电机的数学模型,并提出了相应的解析算法。采取场路结合的方法,分析不同磁极结构对凸极率、磁阻转矩、电感和波形畸变率等参数的影响。利用上述设计分析方法,对一台30 kW的小型低水头永磁同步发电机进行了优化设计,试验结果表明,该优化设计方案具有可行性和正确性。Based on the operation characteristics of the low head hydro power generation and grid connection principles,a mathematical model of the permanent magnet synchronous generator is established and the corresponding analytical algorithms are proposed either.By means of the field-circuit coupling method,the influenced parameters such as the saliency ratio,magnetic resistance torque,inductance,and waveform distortion rate because of the different pole structure are analyzed.Utilizing the above design and analysis methods,an optimized design for a 30 kW smallscale low head permanent magnet synchronous generator is carried out.Experimental results show that the optimized design scheme is feasible and correct.
