Application of new POSICAST control method to synchronous generator excitation system
Abstract
In this paper, modeling, analysis, design and simulation of a POSICAST controller are presented for application in a generator’sexcitation system. Simple structure is the most important characteristic of this controller. The controller is a feedforwardcompensator; it eliminates intensive over/undershoots in system dynamic response. Since changing the reference signal inthe excitation system of the synchronous generator causes oscillations in the terminal voltage, the POSICAST controller (PC)is applied at the outset of the excitation system to mitigate these oscillations. The impact of the proposed controller on thestability of the studied power system is evaluated by both eigenvalues analysis and experimental results. In order to validatethe theory, the performance of the designed controller is verified in OPAL-RT by experimental approach.References
