摘　　要：电力系统在线安全稳定分析实现了电网运行的在线监测和预警。分析基于实时数据进行在线安全稳定分析的局限性,提出在线安全稳定分析的实时分析、研究分析和趋势分析3种应用模式,分别阐述不同应用模式的研究目的、数据来源和业务流程。介绍在线安全稳定分析的整体工作流程,分析3种应用模式协调运行能够避免基于实时数据分析的局限性。实践结果证明了在线安全稳定分析3种应用模式协调运行能够为大电网运行安全稳定提供有效保障。Power system online security and stability analysis facilitate realization of power grid operation monitoring and early warning. Limitations of on-line security and stability analysis based on proposed real-time data are analyzed, and three kinds of application modes are proposed. Research purpose, source data and processing flow of real-time analysis mode, study analysis mode and dynamic trend analysis mode are expounded respectively. Overall work flow of on-line security and stability analysis is introduced. Coordinated operation of various application modes can eliminate the limitations of stability analysis based on real-time data simply. Analysis results based on a practical case prove that coordinated operation can provide effective guarantee for secure and stable operation of power grid.
