电流型变频调速系统动态模型研究

The Stuby of System Dynamic Model with Electric Current Frequency Conversion Governor

本文主要通过异步电动机电压矩阵方程[1],推导出异步电动机的动态结构图,然后推导出交—直—交电流型变频调速双闭环系统的动态结构图。利用该结构图,在模拟机 DMJ—313上对负载扰动进行了仿真研究。试验表明,调整调节器参数,可使负载扰动指标达到满意的要求,为在设计中选择调节器参数提供了依据。

This paper presents adynamic structural drawing of asynchronous generator, which is the basis of the dynamic structural drawing of alternating—direct— alternating current frequency conversion governor with two close—ring sys- tems.With the aid of the latter drawing,on the DMJ—313 analog computer,a simulation study of load disturbances is carried out.The test shows that by adjusting the regulator parameters the norms of load disturbances can be rea- ched satisfyingly.This provides a basis for choosing regulator parameters in design.
