电能质量扰动信号信号通过hilbert变换得到瞬时频率，瞬时幅值，hilbert谱，边际谱等重要特征，从而实现特征提取。(Power quality disturbance signals are obtained by hilbert transform to obtain instantaneous frequency, instantaneous amplitude, hilbert spectrum, marginal spectrum and other important features, in order to achieve feature extraction.)

说明：  将源码中的地址目录改成所要分析的数据（数据可以使txt格式的），在MATLAB中运行就可以分析出数据的时域和频域图像，自相关互相关函数，以及功率谱图像(The source address in the directory into which to analyze the data (data can txt format), run in MATLAB can analyze the data in time domain and frequency domain image, from the relevant cross-correlation function, and the power spectrum image)

短路电流计算 短路电 流计算 短路电流计算(short-circuit current calculation of short-circuit power flow calculation of short-circuit current calculation of short-circuit current calculation)

说明：  转速、磁链闭环控制的矢量控制交流调速。控制电路是由滞环脉冲发生器、电流变换与磁链观测的封装模块、比例放大器模块、函数模块、常数模块（用于额定转速和转子磁链信号的给定）、转速调节器ASR、转矩调节器ATR、磁链调节器APR、以及三二变换器模块。(Vector Control AC Speed Regulation with Closed Loop Control of Speed and Flux Link)

this is useful to generate noise in communication channels at the time of simulation

说明：  这是个关于图像迭代法分割算法的源程序，在matlab上实现(This is iterative image segmentation algorithm on the source, to achieve in matlab)
