Design and Tuning of Multi-Band Based Power System Stabilizer and Implementation in HYPERSIM

Tuning of Power system stabilizers is an important aspect in maintaining the stability of the grid. Hence, proper tuning of it is gaining more significance recently. This paper presents a detailed tuning of Multi-Band power system stabilizer (MB-PSS) known as PSS4B. Thereafter, it is implemented on a real time simulation software HYPERSIM. A widely used Kundur two area power system model is taken as test case to perform the step-by-step design initially in phasor domain of Matlab. Thereafter, it is implemented in HYPERSIM, an electromagnetic tool capable of performing offline and real time power system analysis. It was shown that the results match very closely and the importance of PSS4B tuning is demonstrated.
