Research On Unified Information Platform Of Hydropower Plant Based On Multi-source Data

With the information construction of the power system for many years,China's power grid is evolving from the traditional power grid to the smart grid.Compared with the traditional physical system,the smart grid is more open and complex,and it is an information system with multi-user,distributed and intelligent features.The smart grid generates a large number of complex and complex data with complex correlations at all times.However,due to the closedness of each system,the problem of “information islands” in the power system leads to the use of these data to mine its value.Become a huge challenge for the power industry now and in the future.In view of the above problems,this paper designs a unified information platform for hydropower plants based on multi-source data,aiming at solving the problem of “information islands” of power systems,breaking through the limitations of traditional information for specific applications,and penetrating the data of all links in hydropower plants.Efficient collaboration between businesses.This paper firstly combines the existing hydropower plant business functions to complete the hydropower plant business function design.Secondly,it is driven by business needs and uses technology exploration as a means to complete the hydropower plant unified information platform technology architecture,realize the heterogeneous multi-source data,and put data resources.Transforming data assets to provide accurate information for data mining and numerical analysis using big data artificial intelligence technology.At the same time,the key technologies in the construction process of the unified information platform of hydropower plants are analyzed,including:(1)An object-oriented unified coding scheme is proposed,and the design of coding rules is completed,aiming at solving the problem of system coding failure;(2)The unified information platform synchronous clock technology is studied,and the IEEE 1588 protocol is adopted to solve the synchronization problem between the system and the device.The simulation accuracy proves that the synchronization accuracy of the scheme can reach sub-microsecond level,and the IEEE 1588 protocol implementation scheme is proposed to meet the current power system.Finally,this paper uses the school dynamic model laboratory to simulate the transformer interphase shortcircuit fault,carries on the experiment verification to the unified information platform fault diagnosis module,proves the rationality and the practicability of the unified information platform.
