摘要： A method and a system for a comprehensive analysis of low frequency oscillation. The method includes: firstly, initiating a wide area measurement system WAMS (71) to perform real-time monitoring; transmitting real-time low frequency oscillation information to a dynamic early-warning system (72) periodically; then converting the low frequency oscillation information received by the dynamic early-warning system (72) 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 (71) and a human-machine system interface for output. The system includes: the wide area measurement system WAMS (71), the dynamic early-warning system (72), a system for stability calculation with small disturbance (73) and an output system (74).
