A Survey on Application of Data Mining in Transient Stability Assessment of Power System

人工智能和数据挖掘在发现潜在问题和提高计算效率等方面有较大的优越性。综述了几年来人工智能与数据挖掘等技术应用于电力系统暂态稳定评估所取得的研究成果。对所涉及的主成分分析、遗传算法、粗糙集、信息熵等数据预处理方法,神经网络与支持向量机等分类器,可视化显示等方面的研究成果进行了深入的分析和比较,指出了存在的问题,并对以后的发展方向进行了一定的展望。

Artificial intelligence and data mining possess obvious superiority in finding potential problems during online and offiine transient stability assessment （TSA） and improving computational efficiency. In this paper, the progress of the research on applying artificial intelligence and data mining to TSA of power system in recent years is summarized. The research results of data preprocessing methods such as principal component analysis, genetic algorithm, rough set and information entropy concerning with the research on TSA and the pattern recognition methods by neural network and support vector machine as well as visualization display are analyzed and compared in detail; the problems existing in these methods are pointed out, and the development trend of these methods in future is prospected.
