摘要
本文利用坐标轴系的变换,推导出控制对象异步电动机的数学模型,进而推导出电压型交-直-交变频调速系统受负载扰动的主回路动态结构图。据此结构图,在模拟机上对电压型变频调速系统进行了负载扰动的分析和研究,在满足扰动性能指标的情况下,能够选择调节器的最佳参数。
In this paper, a mathematical model is formed for controlling asynchronous generators, by means of transformation of the coordinate axial system. Hence has been drawn a dynamic structural dia- gram of the main loop in the alternating-direct-alternating voltage fre- quency conversion governor system under load disturbances. With the aid of this structural diagram, on the analogue computer, the load disturbances to the electric voltage frequency conversion gover- nor system are studied and analysed. Thus, in case when the norms of load disturbances are reached, the best parametres of regulator can be chosen this provides a prerequisite for design.
