Abstract
A method and a system for a comprehensive analysis of low frequency oscillation. The method includes: firstly, initiating a wide area measurement system WAMS () to perform real-time monitoring; transmitting real-time low frequency oscillation information to a dynamic early-warning system () periodically; then converting the low frequency oscillation information received by the dynamic early-warning system () into an input file for stability calculation with small disturbance, and performing related calculation; finally, transmitting the calculated result back to the wide area measurement system WAMS () and a human-machine system interface for output. The system includes: the wide area measurement system WAMS (), the dynamic early-warning system (), a system for stability calculation with small disturbance () and an output system ().
