This paper presents a probabilistic approach to evaluate the reliability of a synchrophasor-based multi-input damping controller. Considering the probabilities of losing input signals to the controller, expected damping for the critical electromechanical oscillatory modes are determined. A two input power system stabilizer that uses a local and a remote signal is considered as a test system to evaluate...
This paper presents a design of a power system damping controller using partial right eigenstructure assignment. The eigenstructure assignment technique selects a set of closed-loop eigenvalues along with their right or left eigenvectors. The selection of eigenvectors offers extra flexibility which is exploited in this paper by designing a robust damping controller which provides the required damping...
Analysis of the impact of communication network infrastructure performance on critical power system applications that rely on wide area synchrophasor measurements can be realistically achieved only through co-simulation of the power system and the synchrophasor communication network. In this paper, a single simulation platform, an electromagnetic transient (EMT) simulation program - PSCAD/EMTDC, was...
This paper presents a case where the design of a Power System Stabilizer (PSS) to achieve desired damping using local speed feedback signals is difficult using the conventional design technique. It is shown that synchrophasor based two input power system stabilizer can be designed without much difficulty to achieve the desired damping. Eigenanalysis is performed on the reduced equivalent of New England...
