A New Method for Assessing On-line Small-signal Stability and its Application

시계열 데이터를 이용한 새로운 온라인 미소신호안정도 평가 방법과 적용

This paper describes new on-line small signal stability assessment and its application using the time series simulated phasor measurement data. Using FFT technique and optimization method, the suggested method can effectively identify all of mode frequencies involved in measured data and calculate the damping ratio with accuracy.
