摘　　要：电网调度自动化系统中存在着大量的图形展示文件、断面数据文件等,必须考虑如何方便、可靠地管理这些文件。分析了调度自动化系统中文件的类型及特点,提出一种轻量级分布式文件管理,通过冗余存储保证数据可靠存储,采用基于日志的增量同步维持冗余节点之间数据一致性,利用同步锁解决文件同步过程中主备机切换可能导致数据不一致问题,通过该技术可以轻便、可靠地管理文件。该文件管理已在多个省调、地调自动化系统中得到应用。The existence of large numbers of files in a dispatching automation system asks for easy and reliable management. Based on an analysis of the types and characteristics of the dispatch automation system files ways of their a lightweight method for file management using the local file system directly to manage files is proposed. A strategy based on log files is engineered to maintain file consistency while a synchronous lock is adopted in the file synchronization process to resolve standby machine switching that may lead to data inconsistencies. This method is applied in a dispatching automation system.
