| Abstract: | With a large number of fast excitation devices put into use in the modern power grid, the low-frequency oscillation phenomenon becomes increasingly serious, which leads to potential threats to the safe and stable operation of the power system. The new power system stabilizer PSS4B has good restraining effects on the low-frequency oscillation. This paper analyzes the causes of the low frequency oscillation before introduces the model, advantages and parameter settings of the PSS4B device. Furthermore the PSS4B is applied to a four- machine two-area system, and the results are compared with those with no PSS and with ordinary PSS. The results confirm that the PSS4B can more effectively suppress the low-frequency oscillation under both the inter-area mode and the local mode, thus improves the stability of power system. |
