A Survey Paper on Power System Stabilizer to Damped Out the Inter-Area Oscillations




Geometric Approach, Inter-area oscillations, Power System Stabilizer


Power system oscillation damping remains as one of the major concerns for secure and reliable operation of large power systems, and is of great current interest to both industry and academia. The principal reason for this is that the inception of poorly-damped low-frequency inter-area oscillations (LFIOs) when power systems are operating under stringent conditions may lead to system-wide breakups or considerably reduce the power transfers over critical corridors. With the availability of high-sampling rate phasor measurement units (PMUs), there is an increasing interest for effectively exploiting conventional damping control devices, such as power system stabilizers (PSSs), by using these measurements as control input signals. In this paper, we provide a comprehensive overview of distinct elements (or ‘‘building blocks’’) necessary for wide-area power system damping using synchrophasors and PSSs. These building blocks together shape a tentative methodical framework, and are disposed as follows: (1) fundamental understanding of the main characteristics of inter-area oscillations, (2) wide-area measurement and control systems (WAMS and WACS) and wide-area damping control (WADC), (3) methods for model-based small-signal analysis, (4) control input signals selection, and (5) methods for PSS control design. We also describe the latest developments in the implementation of synchrophasors measurements in WAMS. In this paper research read many papers related to signal selection approach for WADC designed which is based on two different approaches namely: Residue approach and Geometric approach.
