摘要
为改善电网质量并实现异步电动机的四象限运行,将矩阵变换器作为变频调速系统的功率变换电源,结合异步电动机矢量控制策略,构成高性能的"绿色"交流调速系统.采用空间矢量调制作为矩阵变换器的控制策略,综合异步电动机转子磁场定向理论,搭建系统仿真模型,对系统优质的抗扰能力及四象限运行特性进行分析验证,展现了该新型交流调速系统的广阔发展前景.
In order to improve the quality of the grid and realize four quadrant operation of induction motor, matrix convert was used as power supply, combined with vector control strategy to compose high performance and non-pollution AC speed regulation system. Using space vector modulation strategy to control matrix converter, synthesized with rotor flux oriented theory to build simulation model, anti-disturbance capability and four quadrant operation characteristic is analyzed to show the extremely broad development in the future,
