RIASCOS, Felipe e CEPEDA, Jaime. Mathematical Modeling of Speed Control System of Generation Units from Coca Codo Sinclair Hydroelectric Power Plant. Revista Técnica energía [online]. 2021, vol.18, n.1, pp.59-71. ISSN 2602-8492. https://doi.org/10.37116/revistaenergia.v18.n1.2021.469.
In the present study, a process for modeling and validation of parameters of the speed control system, governor and turbine, from the generation units of Coca Codo Sinclair hydroelectric power plant was developed. For this purpose, the potentiality of DIgSILENT PowerFactory software is used to implement the transfer function blocks. Subsequently, the model is validated through parameter identification using the heuristic algorithm mean-variance mapping optimization (MVMO), based on records obtained through phasor measurement units (PMU) of a real-time event that occurred in the National Interconnected System (SNI). To develop the model in this study, three types of Pelton turbine and speed regulator models with different complexity were analyzed. The availability of a validated and tested model of the generator speed control system will guarantee sufficiently precise simulations that accurately represent the real behavior of the hydroelectric power plant, which is an important premise for making adequate decisions in relation to control and technical economic actions.
