摘　　要：熔盐堆(MSR)使用的是高温熔融态的混合熔盐作为冷却剂,在冷却剂回路中,伴热保温模块是其中重要的组成部分。为防止高温熔盐凝固堵塞输送管道、减缓加热过程中结构材料的应力变化,准确且稳定的管道加热保温控制是反应堆安全运行的重要保障。提出了一种自适应PID方法,经过仿真对比分析表明,所提出的方法超调量小、调节时间短、升温速率稳定,能够满足技术指标,并且能为熔盐堆样机伴热保温模块的控制设计提供一定的工程参考价值。The molten salt reactor(MSR)uses high-temperature molten mixed molten salt as the coolant.In the coolant circuit,the heat-tracing insulation module is an important part of it.In order to prevent the solidification of high-temperature molten salt from clogging the transportation pipeline and slow down the stress changes of structural materials during the heating process,accurate and stable pipeline heating and insulation control is an important guarantee for the safe operation of the reactor.This paper proposes an adaptive PID method.The simulation and comparative analysis show that the proposed method has small overshoot,short adjustment time,stable heating rate,can meet the technical indicators,and can be used for the control of the heat tracing and heat preservation module.The design provides a certain engineering reference value.
