摘要:
 针对低风速段开关磁阻风力发电机的运动电动势低于发电电动势、导致发电区间小于励磁 区间的问题,将 Z 源网络耦合到励磁电源与不对称半桥功率变换器之间,强化励磁电压,加快励磁 电流上升速度,减小励磁区间,提高低速发电效率; 同时给励磁电容充电,实现快速自励; 并通过 Z 源网络实现滤波,节省成本,减小体积。Matlab 仿真实验表明: 与传统不对称半桥功率变换器相比, 基于 Z 源网络新型功率变换器能明显提高 SRG 在低速段风能利用率和发电效率。20 kW 小功率 样机测试结果也验证了新型 Z 源网络功率变换器能优化开 SRG 低速性能。

Abstract:
 In low wind speed,the motional electromotive force of switched reluctance generation( SRG) is lower than the generation electromotive force,resulting in generate electricity interval less than the excita-tion interval. Aiming at these problems,Z-source network was coupled between the excitation power source and asymmetrical half-bridge power converter. It has many advantages,such as strengthen the ex-citation voltage,accelerating the rising speed of excitation current,shrinking excitation interval,increas-ing the efficiency of low speed power generation,and charging the excitation capacitor to achieve rapid self excitation. The cost can be saved,and volume can be reduced with self-filter by Z-source network. MATLAB simulation result shows that the new power converter based on Z-source network can improve the low speed wind energy utilization and SRG power generation efficiency,compared with the traditional asymmetrical half-bridge power converter. Small power prototype test result also verified that the new Z-source network power converter can optimize SRG low performance.
