Automatic V-Curve Analizer for synchronous generators

Resumen

Synchronous machines are electrical components that possess characteristics that make their modeling complex, such as the excitation system, magnetic saturation, and the fact that their physical construction involves both mechanical and electromagnetic aspects. A correct modeling of synchronous machines is fundamental for studies focused on the quality of factors for the same driven load, whether mechanical (in the case of motors) or electrical (in the case of generators). This behavior is represented by the V-curve, which shows the ability of the synchronous machine to vary the power angle by absorbing or supplying reactive power to the grid, by adjusting the excitation current when the machine operates at constant power. The analysis of the V-curve of the synchronous generator is carried out through tests that require multiple stages, as well as constant conditions during their execution, such as rotational speed of the system and supplied power.
