| 摘要: |
| 随着PMU／WAMS技术的广泛应用，基于广域响应的暂态稳定紧急控制技术已成为可能。在基于区间联络线能量预测紧急切机方法的基础上，结合基于电压轨迹的暂态失稳判别方法，提出一种适用于互联电网区间暂态失稳的暂态稳定控制技术。该技术采用主站-子站控制方式进行区间暂态失稳判别与紧急切机控制。针对复杂故障下南方电网两广断面暂态失稳，建立详细的工程化控制方案。探讨所提紧急控制技术与现有安全稳定防线的协调配合问题。仿真结果表明，采用所提方法能够制定合理、有效的紧急切机策略，维持电网的安全稳定运行。 |

| Abstract: |
| 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. |
