| 摘 要： | 在分析与总结了余热发电机传统功角测量方法的基础上，提出了基于DSP技术的功角测量方法，充分利用在信号分析与处理方面的优势，先进行同步采样得到电压、电流的采样序列，再进行数字滤波和傅氏滤波可以精确得到基于工频分量的功角，最后仿真并证明了此方法的正确性。

| Abstract: | By analyzing the conventional power angle measurement methods, a new measurement method of power angle based on DSP technology is proposed. Making full use of the advantages of DSP in signal analysis and processing, software synchro nous sampling is performed in advance to get the sampling series of voltage and current. Then digital filtering and Fourier filte ring are conducted to gain the accurate power angle based on power frequency fundamental component. Simulation result dem onstrates the correctness of this method. |
