摘要
针对电力推进船舶电网频率的实时精确检测,阐述了基于二阶直接型IIR数字陷波器的基本原理,基于LMP(p=3)自适应算法建立了在跟踪陷波器参数基础上的船舶电网频率实时检测模型,并分别在电网频率不变、频率发生阶跃变化以及频率线性变化的不同情况下进行了基于Simulink的仿真研究。仿真结果验证了提出的频率检测方法的实时性和精确性。
With respect to precise and real-time detection of power frequency for an electric propulsion ship,a second-order direct type of IIR digital notch filter is described,and a real-time frequency detection model is established based on LMP（p = 3） adaptive algorithm to track the notch filter parameters.Simulation is carried out under different situations including fixed frequency,step change in frequency and linear variation of frequency based on the software Simulink.The real-time capability and the accuracy of the proposed frequency detection method are validated with simulation results.
