针对交交变频器 除产生5、7、11、13次谐波外，还产生旁频，谐波内容多的主要特点，进行了 滤波器装置方案选择，确定滤波器形式，并对滤波器参数进行了工程设计计算。 TCR+FC型Svc通过采用单独的相一相控制能调节三相电源的容抗和感抗来 补偿轧机系统的不平衡，从而降低35KV供电电网的损耗。(In addition to produce5,7,11,13 harmonic, also produced by frequency, harmonic content of main feature, undertook Filter device selection, determine the filter, and filter parameters for the calculation of Engineering design. TCR+FC Svc through the use of separate phase to phase control can adjust the capacitance and inductance for three-phase power supply Compensation system of rolling mill of imbalance, thereby reducing the power consumption of 35KV. )

傅 立叶变换是数字信号处理领域一种很重要的算法。要知道傅立叶变换算法的 意义，首先要了解傅立叶原理的意义。傅立叶原理表明：任何连续测量的时序或 信号，都 可以表示为不同频率的正弦波信号的无限叠加。而根据该原理创立的 傅立叶变换算法利用直接测量到的原始信号，以累加方式来计算该信号中不同正 弦波信号的频 率、振幅和相位。 (The goals for the course are to gain a facility with using the Fourier transform, both specific techniques and general principles, and learning to recognize when, why, and how it is used. Together with a great variety, the subject also has a great coherence, and the hope is students come to appreciate both. )
