Research on Dynamic Parameter Model of Electrical Performance of Reactor Control Rod Drive System

因缺乏反应系统动态变化过程的电气性能精准参数模型,现有核电厂控制棒驱动系统在不同环境条件下的控制效果不佳。本文建立了系统静态电磁仿真模型,通过状态分类的方式获取了系统全工况下的电气性能参数(电阻、电感)和电磁力离散数据,基于数据建立了控制棒驱动系统动态过程中电流、电磁力、衔铁位移和加速度的动态参数模型及算法。该算法最终通过电磁模型、电路模型与数值仿真相结合的形式进行了验证,可以模拟实际系统的运行状态,具备了仅依靠控制指令和当前时刻电流即可预测下一时刻系统电气性能参数的能力。本文构建的动态参数模型可为制订高效率的智能控制策略奠定基础。

Due to the lack of accurate parameter model of electrical performance in the dynamic change process of the reaction system,the control effect of the existing control rod drive system in nuclear power plant is not good under different environmental conditions.In this paper,the static electromagnetic simulation model of the system is established,and the electrical performance parameters(resistance,inductance)and electromagnetic force discrete data of the system under all conditions are obtained by state classification.Based on the data,the dynamic parameter model and algorithm of current,electromagnetic force,armature displacement and acceleration in the dynamic process of the control rod drive system are established.The algorithm is finally verified by the combination of electromagnetic model,circuit model and numerical simulation,and it can simulate the running state of the actual system and has the ability to predict the electrical performance parameters of the system at the next moment only by relying on control instructions and current.The dynamic parameter model constructed in this paper can lay a foundation for the formulation of efficient intelligent control strategy.
