摘　　要：电网基础数据类型多、变化关系复杂,地理空间、时间周期跨度大,数据追溯困难,该文提出基于区块链技术的电网多源数据追溯方法。根据电网基础数据时空分布及数据流变动性特点,建立了基于区块链的多源数据追溯架构,研究了数据追溯依赖关系及溯源路径结构。提出了基于有限状态机模型的数据溯源的路径结构分析图,及路径构建算法,研究了多源时空数据区块的平行追溯方式。构建了基于有限状态机溯源路径的电网多源时空数据追溯优化流程,研究了多层次溯源数据区块时空序列关联性。工程实例表明,基于区块链、有限状态机可高效灵活追溯电网基础多源时空数据的完整可信分布序列。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 multisource 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.
