Technology of On-line Power System Stability Evaluation and Decision-making

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 of 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 Fujian power system is introduced.
