Simulation of Frequency Regulation Loop for AC Power Supply Based on MATLAB

摘要:

在介绍某型恒频交流电源频率调节环路的组成和工作原理的基础上,分析了频率调节环路各组成部分的数学模型,建立了频率调节环路总的数学模型。文章重点讨论了某型发动机在中转速中负载状态下,改变滤波整形放大电路频率调节环路前向通道和反馈通道参数对系统动静态特性产生的影响。利用 MATLAB仿真工具对系统进行了变参数仿真,得出了相应的仿真曲线,并对仿真结果进行了动静态特性分析。该仿真结果具有很好的应用价值。

Abstract:

Based on the introduction of components and principles of frequency regulation loop of constant fre. quency AC power supply, mathematic model of frequency modulation system was established. In this paper, the simulation with parameters changed under the state of middling rotate speed and middling load of the engine was discussed with emphasis. The simulation results showed that the change of system parameters would affect the dynamic and static characteristics of the system. The simulation results have good application value.
