摘　　要：随着核能供暖技术的发展,核供热堆需要更高效经济的运行方式。为降低供热成本,满足季节运行需求,实现“无人值守”,实现启动并稳定运行的自动控制系统对供热堆而言是十分迫切的需要。本课题基于MATLA B/Simulink软件对200MW低温供热堆的启堆过程进行模拟和计算分析,针对供热堆从次临界到临界的过程做了初步设计的自动启动控制方案。仿真结果表明,该自动控制方案能基本满足低温供热堆安全启动的要求。With the development of nuclear heating technology,nuclear heating reactor needs a more efficient and economical operation mode.In order to reduce the heating cost,meet the seasonal operation demand and realize"unattended",it is very urgent for the heating reactor to realize the automatic control system with start-up and stable operation.This paper simulates and calculates the start-up process of 200MW low-temperature heating reactor based on MATLAB/Simulink software,and makes a preliminary design of automatic start-up control scheme for the process from subcritical to critical.The simulation results show that the automatic control scheme can basically meet the requirements of safe start-up of low temperature heating reactor.
