摘要：To solve the data management problems of the operation monitoring center of power grid enterprises: the lack of a unified management standard, information island and privacy protection, we propose a data asset space model of power grid-DAEVP to organize the power grid data asset more efficiently. The model can uniformly represent the heterogeneous data asset distributed in different business departments of the power grid enterprises, thus make the operation monitoring center own the control right as well as protect the privacy of the power grid data asset; At the same time, a power grid data asset algebra is proposed to solve the operation problem of the power grid data asset. A set of power grid data asset operators defined by the power grid data asset algebra can represent the behavioral semantics of the power grid data asset; in the meanwhile, the orthogonality and closure properties of the data asset operators are proved.
