Determination of Generator’s Capability Curve and Monitoring Impact of Generating Transformer Tap Changer on Reactive Power Output
Authors: Bimal Gyawali, Nava Raj Karki
Abstract—The operation of a synchronous generator is limited by certain constraints. Due to the variation of operating conditions the originally provided capability curve may be insufficient to obtain an accurate operating region. The study presented in this paper fulfills the need for actual visualization of capability diagrams using the MATLAB software environment. The simulation and study of variation on the PQ loading after occurrence of possible disturbance scenarios on the power system network is carried out in PSAT (Power System Analysis Toolbox) software. The Generator capability curve is developed from the data obtained after time domain simulation applied on an IEEE 9 bus power system. From the simulation studies, the changes are observed in the operation of the generator based on various events. Besides, the reactive power generation alteration with the tap position of the generating transformer is studied.
Keywords—Synchronous generator, (GCC) Generator capability curve, MATLAB, PSAT (Power System Analysis Toolbox, Transformer tap changer.
