Análisis en estado estacionario y verificación del sistema de protecciones en las líneas de transmisión de las subestaciones adyacentes ante la incorporación del Parque Eólico Minas de Huascachaca al Sistema Nacional de Transmisión

Abstract

In this degree work, an analysis of the electrical impact of the incorporation of the Minas de Huascachaca Wind Farm (MHWF) in the 138 kV National Transmission System (NTS) is carried out. The work begins with a brief description of the elements of the Electrical Power System (EPS) and its balanced and unbalanced steady state analysis methods. It continues with the technical description of the wind turbines and associated equipment; then, a statistical study of the wind speed at the MHWF site is carried out, with the objective of determining the average speeds and thus being able to estimate the output power of the wind turbines at the time of electric energy production; The estimated generation power and the technical data of the MHWF allow performing the steady state analysis of the EPS associated to the MHWF before and after the incorporation of the MHWF for minimum, average and maximum demand in dry and rainy periods; to then perform the analysis of contingencies N – 1 after the incorporation of the MHWF. The work continues with a study of short circuits of the bars associated to the MHWF; as well as the verification of the protection system of the lines adjacent to the La Paz substation. It ends with conclusions and recommendations. All calculations and simulations were performed using DIgSILENT PowerFactory software.
