Abstract


In a power system where the traditional synchronous generators are used for power generation, uncertainty exists because of small, continuous perturbations, such as minor load fluctuations, and insufficient damping which can lead to low frequency oscillation. To maintain the power system stability which involves damping of the low frequency oscillations, we can introduce Robust Damping Controllers using a combination of PSS and STATCOM. This paper presents the Design and Simulation of Robust Damping Controllers for Small-Signal Stability Enhancement Using PSS and STATCOM in a Multi-Machine System. This was achieved by modelling a 9-bus power system which is the Multi-Machine System, modelling a STATCOM, also modelling a PSS using MATLAB Simulink and finally simulating the entire system after the STATCOM and the PSS models were incorporated into the Multi-Machine System. The outcome of the analysis reveals that the design combination of the STATCOM and the PSS has an exceptional capability in damping a power system’s low frequency oscillations, and it also greatly improves the dynamic stability of power systems.
