摘　　要：阐述了电力系统在线安全稳定评估及决策的概念及其对电网预防控制、暂稳控制、电压稳定控制等方面的重要作用,认为电力系统在线安全稳定评估及决策是今后电网稳定运行和控制的发展方向。对实现在线评估及决策的条件进行了分析和评述,指出电力系统运行状态数据采集的快速性、同时性、可靠性是实现在线评估及决策系统的重要基础,提出了构建电网统一数据平台的设想和建议,并介绍了福建电网在线决策系统的工程实践。The concept of the on-line power system stability evaluation and decision-making system and its contribution to preventive control, transient stability control and voltage stability control are introduced. On-line stability evaluation and decision-making is the trend of power system operation and control technology. The qualification of the on-line stability analysis is described, and author presents that the speed, simultaneity and reliability o{ the SCADA data are the important foundation of the on-line calculation. The concept of the uniform data processing system is also presented. As an example, the on-line transient stability control system in Fuiian power system is introduced.
