摘要
介绍了以自主研发的热工软件SimTherm和SimFluid为验证对象,研究基于全电厂系统模拟的热工软件多物理耦合动态验证技术。将热工软件SimTherm和SimFluid与RELAP5、J-Topmeret与RINSIM仿真平台集成并以M310机组为对象搭建一回路和主蒸汽稳态模型。基于两类热工软件搭建相同模拟范围模型,和M310机组辅助系统模型与控制模型耦合,形成可实时计算的多物理耦合动态边界条件。进行两个样机模型的偏差计算,稳态工况下对重要参数偏差结果进行定量分析,瞬态工况下对计算结果与机组结果进行定性分析。结果证明,热工软件SimTherm和SimFluid的满功率稳态计算结果偏差较小,对瞬态工况,事故前期计算基本符合,事故后期存在一些差异。
This article presents a research on the dynamic verification technique of multi-physics and multisystems coupling in thermal-hydraulic software based on the independently developed software SimTherm and SimFluid.The study compares the software SimTherm and SimFluid with RELAP5,J-Topmeret,and integrates RINSIM simulation platforms and constructs a primary loop and main steam system model in steady-state using the M310 Nuclear Power Station as the object.Models with the same simulation scope are built based on the two types of thermal-hydraulic software,and the auxiliary system model and control model of the M310 are coupled to form dynamically coupled boundary conditions that can be calculated in real-time.Deviation calculations are performed on the two models,and the deviation results of important parameters under steady-state conditions are quantitatively analyzed.Under transient conditions,the calculated results are qualitatively analyzed and compared with the qualitative analysis.The results demonstrate that the full-power steady-state calculations of the SimTherm and SimFluid software have small deviations,and for transient conditions,the calculations in the early stages of accidents are generally consistent,but some differences exist in the later stages of accidents.
