本文提出了使用相量测量单元（PMU）的数据触发一次控制，以响应失步检测。决策树（DT）被训练为将电压幅度和角度测量与失步相关联。DT构造过程的不同方法在本文的前面部分通过将输入向量限制为仅两个元素来说明。基于响应的控制通过在DT第一次将测量分类为“不稳定”时触发单次控制来获得。当DT第一次输出“不稳定”时，相同的一次性控制组合将应用于任何事件。该方法被证明在176总线降阶模型的美国西部互联。一个有效的单次控制包括四个总线上的快速功率变化的组合。这种控制类似于两个HVDC互联网上的500 MW快速功率增加，并且它减少了AC网络中的角度差。
This paper proposes using phasor measurement unit (PMU) data to trigger one-shot control in response to loss of synchronism detection. Decision trees (DTs) are trained to associate voltage magnitude and angle measurements with loss of synchronism. Different approaches to the DT construction process are illustrated in an early section of the paper by restricting the input vector to only two elements. Response-based control is obtained by triggering one-shot control the first time the DT classifies measurements as “Unstable”. The same combination of one-shot controls is applied to any event the first time the DT outputs “Unstable”. The method is demonstrated on a 176-bus reduced-order model of the western U.S. interconnection. An effective one-shot control consists of a combination of fast power changes on four buses. This control is similar to 500-MW fast power increases on two HVDC interties and it reduces angle differences in the AC network.
