多堆多机核动力装置控制方案建模及仿真研究

为满足多堆多机核动力装置灵活快速的负荷跟踪及特殊情况下的稳定安全运行,核动力装置控制系统除了需要满足典型运行工况(如:快速升降负荷、甩负荷工况等)控制要求,还应满足在特殊工况下(如单堆多机、单多堆单机等)核动力装置能够平稳安全运行,使多堆多机核动力装置更加灵活的跟踪负荷变化.根据多堆多机核动力装置系统,建立了多堆多机核动力装置控制方案动态仿真模型,包括控制对象和控制方案模型,并对多堆多机核动力装置特殊工况下的瞬态控制过程进行了仿真分析.仿真分析结果表明,控制方案能够实现核动力装置在特殊情况下的工况转换,满足核动力装置稳定运行需求,维持船用负荷和动力的平稳.

The Modeling and Simulation Research on Control Scheme of Multi-reactor and Multi-turbine Nuclear Power Plant

To make sure the quick load tracking and stable operation in particular cases,the control system of nuclear power plant demands not only the control of typical working condition(such as:fast power increase/reduction,load dump),but also stable operation of nuclear power plant in special working condition(such as single-reactor and Multi-turbine,Multi-reactor and single-turbine),to improve the ability of quick load tracking of Multi-reactor and Multi-turbine Nuclear Power Plant (MM-NPP).In this paper,as the system of MM-NPP,the simulation models of nuclear power plant are established,which include the models of controlled member and control system.And its dynamic characteristic of MM-NNP in special working condition is simulated.The simulation and research results show that the control system can meet the need of condition transformation in special working condition and MM-NNP stable operation,keep the marine load and power smooth and steady.
