英文摘要：

With the wide application of PMU / WAMS,the transient stability emergency control technology based on wide-area response has become possible. According to the emergency generator tripping control based on tie-line energy prediction and the transient instability detection based on voltage trajectory,a scheme of inter-area transient stability control is proposed for the interconnected systems,which adopts the master-slave control mode to carry out the inter-area transient instability detection and emergency generator tripping control. As a project,a detailed transient instability control scheme is established for the Guangdong-Guangxi section of China Southern Power Grid under a complex fault. The coordination between the proposed control method and the current safety stability defence line is discussed. Simulative results show that,a rational and effective emergency generator tripping strategy is set by the proposed method to maintain the safe and stable operation of power grid.
