摘要
:为解决故障状态下的核动力装置数据源问题,本文建立了核动力装置一、二回路系统的模型,选择秦山一期核电站为对象,利用RELAP5对蒸汽发生器U型管破裂进行计算。通过结果分析可知所建立的模型节点划分是合理的、数据卡编制准确,基于该模型产生的数据可信。将开发的数据与基于神经网络的故障诊断系统联调,诊断测试结果表明数据准确、充分,可以为核动力装置的故障诊断系统的研究提供数据支持。
The model of nuclear power plant primary and secondary circuits was established, taking Qinshan Unit 1 as the object. The fault of SG U-tube rupture was calculated based on RELAP5 for solving the fault data source problem. Through analyzing the calculation results, we can know that simulation node is reasonable, input data card is exact, and data based on this model is credible. The designed data combining with fault diagnosis system has been debugged. The result indicates that the data is exact and enough and can be one of the databases for study on fault diagnosis of nuclear power plant.
