摘要
提出一种基于广域测量系统WAMS(Wide areaMeasurementSystem)的电力系统暂态稳定实时快速定量分析的方法。该方法根据PMU实时采集的各发电机转子角速度及电磁功率,通过预测扰动结束后系统运动轨迹和基于暂态能量的轨迹分析法来评估系统的暂态稳定性。在 6机系统上进行仿真计算,结果表明,该方法能有效预测电力系统的暂态稳定性。
A new real-time quantitative method for transient stability analysis is proposed. This method employs data collected by WAMS(Wide-area Measurement System), including generator rotor speed and electromagnetic power, to predict transient stability of power systems. The underlying principle is quick prediction of the dynamic trajectory of disturbed power system and transient-energy based trajectory analysis. Simulation with a six-machine test system validates the effectiveness of the proposed method. This project is supported by National Natural Science Foundation of China(No.50323002).
