时变时滞广域电力系统稳定性分析

针对含有时变时滞的广域电力系统稳定性进行了分析.首先,建立含有时变时滞的广域电力系统模型,构建新型L-K泛函.然后,引入一个关于时变时滞的二次函数,再通过积分不等式得到更低保守性的时变时滞广域电力系统的稳定性判据.最后,采用典型的二阶系统和四机十一节点系统,在Matlab上进行仿真,并将所得结果与其他文献结果进行比较分...

Stability Analysis of the Wide-Area Power System with Time-Varying Delay

An analysis has been made of the stability of a wide-area power system with time-varying delay. First, a wide-area power system model with time-varying delay is to be established, followed by the construction of a new L-K functional. Then, by introducing a quadratic function with respect to time-varying delay, a more conservative stability criterion can be obtained through integral inequality of the wide area power system with time-varying delay. Finally, the typical second-order system and four machine eleven bus system are simulated on Matlab, with the results compared with the results of other literatures, thus verifying the feasibility and superiority of the currently proposed method.
