摘　　要：调度自动控制软件是调度自动化系统的核心。近年来,发生了一些运维人员在工程现场随意变更调度自动控制软件版本,导致现场运行版本与测试通过版本不一致,进而造成软件运行异常的不良后果,严重影响了系统安全稳定运行。针对软件版本一致性问题,提出了一种基于改进默克尔树与区块链的电网调度自动控制软件版本一致性管控方法。设计了基于区块链的调度自动控制软件版本管控流程,结合调度自动控制软件特点,提出改进默克尔树对软件版本标注算法,提高了软件版本标识的安全可靠性;运用区块链技术进行软件版本信息上链存储,确保版本信息可核查、可追溯;设计了软件版本切片一致性校验方法,解决了调度自动控制软件测试和现场运行环境不一致导致无法校验的问题。最后,以自动电压控制软件为例,验证了所提出的软件版本一致性管控方法的有效性。The dispatching automation control software is the core of the dispatching automation system.In recent years,some operation and maintenance personnel have changed the software version at will on the project site,resulting in inconsistency between the on-site running version and the tested version.This kind of problem causes abnormal software operation and seriously affects the safe and stable operation of the system.Aiming at the problem of software version consistency,a version consistency control method of power grid dispatching automatic control software based on improved Merkel tree and blockchain is proposed.This paper designs the version control process of dispatching automatic control software based on blockchain.Combining with the characteristics of dispatching automatic control software,it proposes an improved Merkel tree algorithm for software version labeling,which improves the security and reliability of software version information identification.Then,blockchain technology stores software version information on the chain to ensure that the version information can be checked and traceable.Then,a software version slice consistency environment.Finally,taking automatic voltage control software as an example,the effectiveness of the proposed software version consistency control method is verified.
