For a variety of reasons, the power industry and the Internet after the integration of a large number of data. In the era of big data, how to effectively mine, efficiently process and manage the massive data has become the focus of attention. With the development and application of information technology and Energy Internet, a large amount of information is gathered together to form a mass of data, which needs to be mined, cleaned and analyzed to be effectively applied.
