摘要
风险监测系统中使用的顶层逻辑大链接故障树模型存在一种房型事件,其逻辑取值可能因不同始发事件或序列不同,而存在取值冲突现象。普通的故障树计算引擎一般不能处理,为正确处理该类问题,本文提出了一种前处理与后处理相结合的计算方案。测试结果表明,针对实际电站模型,该方法可较好地处理房型事件取值冲突的问题。
Risk monitor has a difficulty in handling the logical value conflict of house events in different event trees or sequences in a top logical model. This conflict is not handled by most of the fault tree calculation engine. A strategy that combined the pre-process and post-process was proposed in this paper. The results show that it could eliminate the conflicts between different values of a specific house event. It is demonstrated that this strategy could properly handle such problem in a real power plant model.
