摘要
DCS控制系统事件顺序记录(Sequence Of Events)SOE模块性能包括分辨率和精度,是衡量控制系统技术性能的主要指标,其性能好坏直接影响机组事故分析的及时性和准确性,对分析判断电厂事故原因具有非常重要的作用。本文基于Ovation 3.5.1控制系统,介绍了SOE模块性能的测试条件、测试设备、测试方法和测试结果,验证SOE模块的分辨率同一控制器内≤1ms,不同控制器间分辨率≤2ms;事件记录的精度小于等于2ms。
The performance of SOE module includes resolution and precision,it is the main indicator to measure the technical performance of the control system.Its performance directly affects the timeless and accuracy of the units accident analysis,and plays an important role in analyzing and judging the cause of power plant accidents.Based on Ovation 3.5.1 control system,this paper introduces the test conditions,test equipment,test method and test results of SOE module performance,Verifies that the resolution of SOE module no more than 1ms in the same controller and no more than 2ms between different controllers,the precision no more than 2ms.
