Power System Small Signal Stability Analysis Based on Test Signal
نویسندگان
چکیده
In this paper, a method based on some test signal (Test Signal Method) is developed to find the dominant oscillating frequencies and dampings associated with any generator in the system. The method can be realized easily by time domain simulation using electromechanical transient programs. The theoretical background of the test signal method is the theory of mechanical admittance and mode identification, which is based on the frequency scanning of the test signal and has already been used widely in mechanical engineering. The study cases show that the test signal method developed in this paper can be effectively applied in small signal stability analysis and PSS design.

متن کاملAlleviating the Small-Signal Oscillations of the SMIB Power System with the TLBO–FPSS and SSSC Robust Controller
Power systems are subjected to small–signal oscillations that can be caused by sudden change in the value of large loads. To avoid the dangers of these oscillations, the Power System Stabilizers (PSSs) are used. When the PSSs can not be effective enough, installation of the Thyristor–based compensators to increase the oscillations damping is a suitable method. In this paper, a Static Synchronou...

The delay associated with signal transmission through the wide-area measurement system reduces the functionality of the power oscillation damping control system. One of the important issues is the poor operation of the supplementary controller against delay existence, which limits the efficiency of damping of ancillary equipment, such as SVCs in a power system. This paper as a solution proposes...
