Data assets have gradually become one of the core assets of power generation enterprises. The power plant is facing the problems of various information systems and data volume multiplying, Data redundancy, data coding inconsistency, data dispersion, data idleness, etc. The huge data of the power plant has not been effectively used. In order to efficiently manage and use these data, an integrated Big data platform built according to the characteristics of power generation enterprises came into being. The platform will use data as a valuable asset in core application scenarios such as equipment monitoring and early warning, equipment diagnosis, unit operation optimization, and enterprise business decision-making, which can bring great value to the work of power generation enterprises in the fields of operation, production, operation, safety, and environmental protection.
