This paper presents the development of a novel synchrophasor measurement-based wide-area centralized damping controller to improve the stability of a power system in presence of time-varying delay and packet dropout in the communication network. Two different strategies have been adopted to deal with the input and the output delays. In the first strategy, the system output delay has been compensated...
Power system stabilizer (PSS) tuning is an important and challenging task in today's power system. In order to investigate the use of remote measurements of generator speed signals in respective PSS tuning, data from phasor measurement units (PMUs) are used in this paper. The PSSs parameter remote tuning is illustrated using a real-time digital simulator (RTDS). A MATLAB-based particle swarm optimization...
This paper presents methods and results for experimental performance assessment using Real-Time Hardware-in-the-Loop (RT-HIL) simulation of an Excitation Control System (ECS) for both terminal voltage regulation and power oscillation damping. The ECS configured for this study is Unitrol 1020 from ABB and its performance is assessed for both Automatic Voltage Regulator (Auto) and Field Current Regulator(Manual)modes...
This paper presents the implementation of three different types of Power System Stabilizers (PSS) anda Static Var Compensator with a supplementary Phasor Power Oscillation Damper (POD) control for real-time simulation. The Klein-Rogers-Kundur model is used as test case and the PSS and Phasor-POD's performance is evaluated for both large and small disturbances. Modeling is performed in the MATLAB/Simulink...
A fuzzy logic power system stabilizer is proposed, and a neural network is utilized for its real time tuning to keep its performance optimal under wider ranges of operating conditions. Simulation results show the efficiency of the proposed real time tuning of the fuzzy logic power system stabilizer by the neural network. The proposed fuzzy logic power system stabilizer can be configured by using a...
A microcomputer based fuzzy logic power system stabilizer is implemented to an actual hydroelectric generator with the rating of 5.25 MVA to investigate its efficiency in real time control. The stabilizing signal is determined by using sampled real power signals to damp the system oscillations. The results show the proposed stabilizer improves the system damping effectively subject to various types...
