Studies on the influence of power system stabilizer for stabilizing small-signal in a single-machine infinitive bus system by analyzing eigenvalue of system state matrix

This paper presents approach to Power System Stabilizer (PSS) design and control applied in power plants. This also summaries eigenvalue-based methodology and relevant components to analyze and control in the oscillation system. Particular value features of the state matrix for the electric oscillation system shall be discussed in details. Based on analyzing effects of PSS for stabilizing small signal in a power system compared with cases of without the electric device as above mentioned. It is shown in the results of analysis and emulation that the resistance shall become very stable when further PSS system is used.
