Background: To solve an electric power enterprise for a safe operation of power systems.
Methods: A data acquisition technology based on multi-thread mechanism of data collection technology
is proposed; its application may provide a data acquisition rate of 1832/min and an update cycle of
approximately 30 s to ensure efficient and reliable performance on a large-scale electric power realtime
Results: A power state index diagnosis algorithm is designed.
Conclusion: The on-line real-time diagnosis of the current operating state for the power system is realized,
and its importance is given.
