摘要
提出了一种针对变速恒频电源电压交流畸变的新的检测方法。文中根据傅立叶变换理论 ,设计了采用 TMS32 0 C32 DSP作为 CPU、以 MAX12 0作为 A/D转换器构成的数据采集系统 ;探讨了信号采样频率和截取长度的选取 ;采取了基 2的 FFT变换算法并给出了软件流程图 ;
A new method to detect the extraneous frequency in the VSCF electric power source based on data acquisition is discussed. Fourier analysis theory is used as a foundation. The data acquisition system based on TMS320C32 as a CPU and MAX120 as an A/D converter is designed. The frequency and the length of data acquisition are discussed and the flow chart of the program is also given. The data acquisition is verified by experiments.
