摘要
电磁干扰与船舶电站设备的非线性特性相互作用,导致船舶电站的电网电压和频率会出现高频次、大幅度的随机波动,影响负载设备的正常运行,因此提出电磁干扰下船舶电站自动频载模糊控制方法。通过电磁干扰下的船舶电站运行结构分析船舶电站的动态频载,并计算待控制的船舶电站频载稳态偏差量,以掌握频载波动规律。由此,结合船舶电站实时状态矢量与整体频载量测情况,利用IT2T-S模糊控制技术适应船舶电站的复杂非线性特性,最小化频载稳态偏差量。以此抑制电网电压和频率的随机波动,确保船舶电站的安全平稳运行。实验结果表明,该方法可以在电磁干扰下,合理控制船舶电站频载稳态偏差量,控制后的频率偏差标准差均小于0.08 Hz,说明该方法控制具备一致性与稳定性。
The interaction between electromagnetic interference and the nonlinear characteristics of ship power station equipment leads to high-frequency and significant random fluctuations in the voltage and frequency of the ship power station's power grid,which affects the normal operation of load equipment.Therefore,a fuzzy control method for automatic frequency loading of ship power stations under electromagnetic interference is proposed.By analyzing the dynamic frequency load of a ship power station under electromagnetic interference,and calculating the steady-state deviation of the frequency load of the ship power station to be controlled,the fluctuation law of the frequency load can be grasped.Therefore,by combining the real-time state vector of the ship power station with the overall frequency load measurement,the IT2T-S fuzzy control technology is used to adapt to the complex nonlinear characteristics of the ship power station and minimize the steady-state deviation of the frequency load.To suppress the random fluctuations of power grid voltage and frequency and ensure the safe and smooth operation of ship power stations.The experimental results show that this method can reasonably control the steady-state deviation of ship power station frequency load under electromagnetic interference,and the standard deviation of frequency deviation after control is less than 0.08 Hz,indicating that this method has consistency and stability in control.
