Desarrollo de un módulo de software en el lenguaje de programación Fortran para simulación de eventos transitorios electromagnéticos en unidades de generación

Abstract

In this work, a software module is developed that simulates the response of a hydraulic generation unit to different transitory events. Said unit is composed of a salients pole synchronous generator, an IEEE DC1A voltage regulator (AVR) and an IEEE G2 hydraulic turbine and speed governor (GOV). Also, the electrical system includes a transmission line connected to the synchronous generator and an infinite bus bar, the events available for the simulations are: three-phase short circuits (at infinite bus bar, at transmission line and at generator terminals), variation in the AVR voltage reference and speed and power reference variations in the GOV.

The output signals of the generator for the analysis of transitory events are: voltage and current at terminals, excitation voltage, active and reactive power generated, power angle, angular speed and electric torque of the rotor. To check the validity of the software developed, these signals are compared with simulations made in DIgSILENT PowerFactory commercial program.

Also is included the deduction of the equations used, based on the standards published by the IEEE, as well as fundamental indications refered to use of Fortran programming language.
