| 摘 要： | 对于一种包含一个动态感应电动机模型的3总线电力系统模型进行了分析和仿真，研究了系统的电压骤降特性。电压骤降是指电力系统的电压突然降到了一个不能接受的水平。对系统模型参数的分析与仿真研究表明，电力系统的初始条件及电网的电力需求的变化可以导致系统的电压骤降；通过引入负载特性参数的微扰，可以抑制电力系统的电压骤降特性。仿真结果表明了微扰抑制方法的可行性。

| Abstract: | In this paper, a simple 3-bus power system model which includes a dynamic induction motor model is analyzed and simulated to study voltage collapse. Voltage collapse means the voltage of the electrical system suddenly declines to an unacceptable level. The system parameter analysis shows that the initial conditions, parameters and change of the demand of electrical can result in voltage collapse. When perturbation is applied to the system, voltage collapse can be delayed or controlled. Simulation results show the feasibility of the method. |
