摘要
现有风险监测器通过手动输入设备状态的方式获取电厂的配置信息,连续运行设备的历史运行时间和状态信息并未输入到风险监测器中。实时在线风险监测与管理系统通过自动和手动的方式获取并储存设备的运行状态信息和不同状态下对应的时间,累积失效概率考虑了连续运行设备的历史运行状态和启动到失效的运行时间。以两个并联泵的系统为例给出泵经历了运行、热备用、再运行过程后泵的失效基本事件的分布函数。这个分布函数反映了机组运行过程中瞬时风险与设备历史运行状态和时间有关,瞬时风险曲线随运行时间呈递增趋势。
In the exiting risk monitor, the configuration information of specified plant is obtained by manual input. The historical running status and corresponding times of the devices cannot be put into risk monitor. In the Real-Time On-Line Risk Monitor （RORM） the running status and time of the components are collected and stored by automatic mode and manual mode. The historical running status and time from start to failure are considered in the cumulative failure probability of specified successive operating device. For example, two parallel pumps in a system experience the operation, hot reserve and then operation. The cumulative failure distribution functions of running failure basic event of two pumps are given. The functions show the instantaneous risk is related to the historical running status and time. The instantaneous risk curve shows an increasing trend with the time.
