红沿河核电厂1号机组热态调试期间稳压器压力控制回路扰动试验分析研究

Analysis and Research of HONGYANHE 1# PZR Pressure's Closed-Loop Control Circuit Disturbance Test in HFT

详细分析热态调试期间稳压器压力闭环控制回路扰动试验结果。针对-0.1、+0.5、-0.5 MPa扰动试验过程中出现的不符合验收准则的问题,通过调节比例-积分-微分(PID)微分参数、通断加热器回差等手段优化压力控制回路,最终保证试验结果满足验收准则的要求。试验完成后,将红沿河核电厂1号机组试验结果与宁德核电厂、岭澳核电站机组试验结果进行比较。热态调试期间进行的稳压器压力闭环控制回路扰动试验,对后续临界前试验以及装料后至商业运行前的瞬态试验有着十分重要的意义。

Analyze the regulator pressure control principle of the Hongyanhe unit 1. Analyze and study the disturbance test results of the PZR pressure closed-loop control loop in HFT, which include ＋0.1, -0.1, ＋0.5, -0.5 MPa variation. According to the phenomenon not conforming to the acceptance criteria, put forward the optimization scheme after careful analysis. Optimize the pressure control loop by adjusting the PID differential parameters and the retrace tolerance of ON/OFF heater to get satisfactory results. Compare the Hongyanhe 1# test result with the results of Ningde and Ling＇ao to gain rich experience for HPT and the subsequent unit. The disturbance test on the regulator pressure closed-loop control loop is of great significance to HPT and the transient test from fuel loading to commercial operation.
