Abstract
Oscillations can cause major stability concern in power systems. It is very important to analyze and locate oscillations quickly so that prompt remedial reactions can be taken to increase the system stability. This paper presents a novel multi-delay self-coherence method to locate source of forced oscillations using measurement data. The derivative constrained minimum variance distortionless response (MVDR) algorithm is used to estimate the coherence spectrum. The Performance of proposed method is evaluated with simulation data that is generated using 16-machine 68-bus model. It is shown through case studies that the proposed method can effectively locate the possible source of forced oscillations.
