母线失电后主泵及机群运行的仿真分析

Simulation Analysis of Recator Cooltant Pump and Other Motors Operation after Bus Loss of Power

本文通过建立核电站内电机机群基于状态方程和运动方程的数学模型,给出母线失电后电机机群的矩阵形式的暂态方程组,继而采用MATLAB的数值积分算法求解方程组,最终得到主泵及机群的电压和转速的曲线。主泵及机群的运行情况分析为母线失电后核电厂安全分析提供了更有力的数学模型支撑,同时也可了解其他重要电机的运行情况。

This paper establishes a mathematical model based on state and motion equations for the motor clusters in nuclear power plants,and presents the matrix equations of the motor cluster after the bus is de-energized.Then the numerical integration algorithm of MATLAB is used to solve the equations,and finally the curves of the voltage and the speed of the main pump and the cluster are obtained.The analysis of the operation status of the main pump and the cluster provides a more powerful mathematical model for the safety analysis of the nuclear power plant after the bus loss,and can also understand the operation of other important motors.
