| 摘 要： | 低频振荡是影响电力系统安全稳定运行的重要问题,机网耦合是引发电力系统功率低频振荡的主要原因之一.分析机网耦合引发的多机系统低频振荡机理,在Matlab软件中建立两机互联系统仿真模型.通过仿真分析可知,两机互联系统当受到外加扰动与系统固有频率重合时,同样也会发生共振机理的低频振荡.

| Abstract: | The low-frequency oscillation is an important issue that affect safe and stable operations of electric power system. The machine network coupling is one of the main reasons which cause low-frequency oscillation of power of electric power system. This paper analyzes the mechanism of low-frequency oscillation of multi-machine power system caused by machine net- work coupling. The simulation model of two-machine interconnected system was established with MATLAB software. Through simulation analysis, it is known that two-machine interconnected system also occurs low-frequency oscillation with resonance mechanism when the external dis- turbance coincides with the natural frequency of system. |
