Abstract :
This paper proposes a method of power grid mass data preprocessing. It makes depth analysis about characteristics of smart grid mass flow data and historical data. Smart grid knowledge classification models are designed according to their characteristics. And it gives the method of power grid knowledge extraction method. It used the sliding window model, discrete wavelet transform and improved SSWAT algorithm to preprocess stream data; The data are preprocessed has many advantages such as reliability, real time, high transfer speed and so on. The data can be access information integration platform.
