摘要
监测水火电机组状态,需要对水火电机组状态在线测量数据进行预处理。主要就是判断和校正误差,通过改进观测量变化率检验方法处理显著误差和通过基于SURE的小波阈值去噪法处理随机误差。
In order to monitor the status of the hydro thermal generator, it is necessary to preprocess the on-line measurement data. The main method is to judge and correct the error, and to improve the measurement of the change rate by improving the measurement of the apparent error and to deal with the random error by the wavelet threshold denoising method based on SURE.
