A LOW FREQUENCY OSCILLATION INTEGRATED ANALYSIS METHOD AND ITS SYSTEM

摘要

A kind of method and system, the comprehensive analysis low-frequency oscillation being used for. This method includes: firstly, starting one wide area measurement WAMS (71) is monitored in real time; It sends real-time low-frequency oscillation information and carrys out dynamic early-warning system (72) periodically; Then low-frequency oscillation information and dynamic early-warning system (72) are converted and arrives the input file calculated with small interference stability, and carries out relevant calculating; Finally, it sends result calculated and feeds back to wide area measurement WAMS (71) and a people-machine system interface output. The system includes: wide area measurement WAMS (71), and dynamic early-warning system (72), system (73) is calculated with small interference stability and output system (74).
