Novel applications of data Hubfor electrical devices evaluation experiments in power grid

This paper introduces a new kind of data hub that is used for evaluation experiments of electrical devices. The hubs not only bridge the real-time data flow between on-site experimental equipment to central servers, but also solve the problem of data normalization. The design of the hub also considers the security issues and data protection in power grid internal network. According to the result of its implementation in several provinces, the usage of this data hub can improve the effect of operation and maintenance service for power grid.
