Optimal Design of the Pole Structure of Low Head Permanent Magnet Synchronous Generators
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,induc-tance,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 small-scale low head permanent magnet synchronous generator is carried out.Experimental results show that the optimized design scheme is feasible and correct.
