Abstract: Purpose/significanceWith the development of the new power system, the power quality problem is becoming increasingly complex and changeable. The importance of accurate traceability of power quality data is becoming increasingly prominent. Efficient and stable storage and traceability methods of power quality data in distribution networks have become a technical problem to be solved.Method/processThis research takes the power quality data of the distribution network as the research object, analyzes the integration mechanism of the power quality data of the distribution network and the alliance chain technology, and combines the alliance chain and cloud computing technology to build the storage and traceability model of the power quality data of the distribution network based on the Alliance chain, and expounds the operation mechanism of the model. Finally, the simulation is carried out with the help of python, remix and other development tools.Result/conclusionThe results show that compared with the traditional centralized system and the conven⁃tional blockchain system of the same type, the proposed scheme can effectively reduce the system time delay and improve the quality of power quality data while achieving efficient storage and traceability of power quality data.Innovation/limitationHowever, with the accu⁃mulation of information base, the processing efficiency of each link will be limited when the alliance chain technology is used to process the power quality data of the distribution network, and it needs to be continuously improved in the future.
