Coordinated Q–V Controller for Multi-machine Steam Power Plant: Design and Validation
نویسندگان
چکیده
This paper discusses coordinated reactive power voltage (Q-V) control in a multi machine steam power plant. The drawbacks of manual Q-V control are briefly listed, and the design requirements for coordinated Q-V controller are specified. Theoretical background and mathematical model of the new controller are presented next followed by validation of developed Matlab/Simulink model through comparison with recorded responses in real steam power plant and description of practical realisation of the controller. Finally, the performance of commissioned controller is illustrated on several examples of coordinated Q-V control in real steam power plant and compared with manual control. Keywords—Coordinated Voltage Control, Power Plant Control, Reactive Power Control, Sensitivity Matrix

متن کاملA Robust FACTS Damping Controller Design to Mitigate Interarea Oscillations in a Multi-machine Power System
In this paper, damping of interarea oscillations using simultaneous coordination of static Var compensator (SVC) and power system stabilizer (PSS) is considered. To be effective in damping of oscillations, the best-input signal of power oscillation damper (POD) associated with SVC is selected using Hankel singular values (HSVs), and right-hand plane zeros (RHP-zeros). The 4-machine-2 area...
