| Abstract:Because of its numerous types and complex changing relationships， large geographical span， complex environment and long cycle， the power grid foundation data provenance-tracing is very complex. This paper proposes a data tracing method for power grid projects based on blockchain technology. According to the spatiotemporal distribution of power grid foundation data and the variability characteristics of data flow， a data tracing architecture based on blockchain is established， and the traceability dependence relationship and path structure are studied. The path structure analysis diagram of data tracing and path construction algorithm is proposed based on the finite state machine model. In addition， the parallel tracing method of multi-source spatio-temporal data block is studied. Based on data tracing path of the finite state machine， the optimization traceability process of power multi-source spatio-temporal data is constructed， and the multi-level correlation under multi-traceability spatio-temporal data block sequence is studied. The analysis of engineering examples shows that the traceability method based on blockchain and finite state machine can trace the required complete trusted multi-source spatio-temporal data series efficiently and flexibly. |
