摘要: 对压水堆稳压器的压力和水位控制,提出了一种模糊综合控制方案。采用3个典型模糊控制器分别对电加热器、喷淋卸压阀和上充阀进行控制;在稳压器压力典型模糊控制器中采用了积分分离方法。本文对汽轮机负荷阶跃变化、线性变化、甩负荷3种工况进行了控制系统的仿真实验。结果表明,稳压器的压力以及水位的瞬态和稳态控制性能都得到了较大改善,明显优于GA-FC和PID控制方案。

Abstract: A comprehensive fuzzy control scheme for pressure and water level of PWR pressurizer is presented in this paper, where three typical fuzzy controllers are used to control the electrical heater, spray and relief valves, as well as feed valve, respectively. An integral-separated method is adopted in pressure control system. Computer simulation results in steam load step change, linear change and load-rejection operating conditions have shown that static and dynamic control performance of pressure and water level have been improved greatly, and the TFC based comprehensive fuzzy control scheme is effective and much better than the GA-FC and PID control schemes.
