电力系统暂态稳定性评估综述

Overview of Transient Stability Assessment of Power Systems

电力系统因稳定性破坏导致的停电事故频发,暴露出电力系统运行中的暂态稳定评估方面仍存在技术瓶颈;因此,必须把准确而快速地进行暂态稳定性评估放在重要位置。分别介绍了近年来国内外基于模型分析、基于数据分析和基于概率化分析3个方面的暂态稳定性评估方法研究现状;并展望了未来电力系统暂态稳定性评估领域潜在的研究点。以期为电力系统稳定性分析与控制的学者和工程师们提供有益的参考。

The failure of power systems happens frequently due to the deterioration of system stability,revealing the existing bottleneck in the transient stability assessment aspects in power system operation.Therefore,it is necessary to give priority to fast and accurate transient stability assessment.This paper introduces respectively the research status of the three types of transient stability assessment methods of model-based analysis,data-based analysis and probabilistic analysis at home and abroad in recent years.The potential research points in the field of the transient stability assessment of the power systems in the future are also prospected,so as to provide beneficial reference for the scholars and engineers of power system stability analysis and control.
