In this paper, we propose a new approach to estimate the low-frequency oscillatory modes in power system by using Total Least Square-Estimation of Signal Parameters employing rotational invariance technique (TLS-ESPRIT) based on Least Mean Squares Sign-Data (LMSSD) Adaptive filtering. LMSSD adaptive filtering reduces the effect of Additive White Gaussian Noise (AWGN) from the signal. The proposed...
This paper demonstrates synthesis of a robust wide-area controller for damping inter-area power system oscillation. A wide-area damping controller is more effective in damping inter-area modes in power system as it takes remote signal as feedback in which inter-area oscillations strongly observable. However, with the involvement of remote signal time-delay is introduced in the feedback loop causing...
In a modern power system, damping of an inter-area mode is crucial as it limits the power transfer capability. With the progress in Wide-Area Measurement System (WAMS), now dynamic data from wide geographical areas are available readily. The accuracy of such data motivates to be used as feedback for controllers, which can have better performance. The placement of such controllers and the signals to...
