Stability Analysis of an Automated Regulator for Alternator Terminal Voltage And Reactive Power Control
Subject area: Science,Engineering and Technology · Area of research: Instrumentation & Control
Abstract
The design involves the establishment of a Proportional and Integral (PI) control system from a linear mathematical model using some primary module transfer functions. All parameters are fed into a MATLAB command window to compute the transfer function for each module, and the over-all closed-loop transfer function of the system. The tuned parameters are then tested in the linear system before applying to the non-linear synchronous generator circuits, modelled for a grid power system. The tuned Controller is used to feedback a voltage component of the reactive power output, when compared to a reference value, to an excitation system. The output of this is then channeled to the generator as d.c. voltage pulses to observe its stability. Linear and non-linear output plots are obtained. This research work uses MATLAB R2015a version.
