A LOW FREQUENCY OSCILLATION INTEGRATED ANALYSIS METHOD AND ITS SYSTEM

摘要

A low frequency oscillation integrated analysis method and its system. The method includes: first opening a wide area measurement system WAMS (71) to perform real time monitoring; sending real time low frequency oscillation information to a dynamic early-warning system (72) timely; then transforming the low frequency oscillation information received from the dynamic early-warning system (72) to an input file for a small disturbance stability calculation, and performing related calculation; finally, sending the calculation result back to the wide area measurement system WAMS (71) and a human-machine system interface to be outputted. The system includes: the wide area measurement system WAMS (71), the dynamic early-warning system (72), a small disturbance stability calculation system (73) and an output system (74).
