Abstract: This paper introduced the current state of the automatic safety monitoring system at Xiaowan hydropower station and analyzed the cause reasons for slow operation. Further, the system optimization plan was proposed, then implementation as well as testing were carried out. After the optimization, operating speed of the system was greatly improved and the goals advanced were achieved.

Key words: performance optimization, data partitioning, safety monitoring

摘要： 介绍了小湾水电站工程安全监测自动化系统的当前运行状况，通过对系统运行缓慢进行原因分析，提出了系统优化方案，并进行实施和测试。优化后的系统运行速度较优化前有较大提高，且能达到预先提出的性能目标。
