摘要:
在高速永磁同步电机谐波分析中,主要有解析和仿真两种方法。解析法则适用于连续系 统,而仿真法适用于离散系统的,但两种方法之间关联性问题研究相对较少,针对此问题,提出一种 基于空间矢量脉宽调制( SVPWM) 技术电枢电流谐波解析法和仿真法内在关联的分析方法。根据 连续函数和离散函数的傅里叶级数公式,分析了这两种方法在谐波计算中偏差的分布规律。分析 结果表明,采样频率和负载是离散电枢谐波计算的主要影响因素,随着采样频率的升高电枢电流谐 波呈现振荡阻尼衰减的特性,并收敛于连续系统的解析值,而负载则能降低振荡幅值和提高收敛速 度。构建了基于 DSP 的永磁同步电机系统实验平台,实验结果验证了该分析方法的有效性。
Abstract:
There are two methods in harmonic analysis of the high speed permanent magnet synchronous motor,and they are analytical method and simulation method. The analytical method is suitable for con-tinuous systems,and the simulation method for discrete system. As the relevance of these two methods has been rarely studied,one correlation analysis method was proposed,which is based on the space vector pulse width modulation ( SVPWM) technology. From Fourier series of the continuous function and the discrete function,the deviation distribution law between these two methods in the harmonic calculation was analyzed. The analysis results show that the main influence factors of discrete harmonic calculation of ar-mature are sampling frequency and load condition. The armature current harmonics oscillate damping at-tenuation with increase in sampling frequency and converge to the analytical results of the continuous sys-tem. The oscillation amplitude is reduced and the convergence speed is improved by load. The permanent magnet synchronous motor system experiment platform based on DSP is constructed,and it is confirmed that the correlation analysis method is effective.
