Diseño y construcción de compensación inductiva para modelos de líneas de extra alto voltaje del laboratorio físico de sistemas eléctricos de potencia : diseño y construcción de módulos de compensación inductiva para la línea de transmisión de escala sin transposición.

Abstract

Within the scope of this project, the primary objective is the comprehensive investigation of the representation of extra-high-voltage (EHV) power lines, with a specific emphasis on the electromagnetic and electrostatic phenomena inherent in 500 kV transmission lines. To fulfill this objective, the project entails the intricate process of designing and constructing two three-phase inductive compensation modules. These modules play a pivotal role in mitigating the capacitive effects within the scaled model, which operates at 220 V and 5 kVA, meticulously mirroring the operating conditions of the 500 kV non-transposed transmission line, Coca Codo Sinclair – El Inga. The determination of the appropriate power value for compensating the line model hinges upon the pre-existing compensation mechanisms in the actual 500 kV Coca Codo Sinclair – El Inga transmission line. This determination is facilitated through the application of a conversion factor and substantiated by extensive simulations executed within the DIgSILENT Power Factory software. With the compensation powers ascertained, the subsequent step involves the meticulous determination of electrical and physical parameters essential for the construction of two specialized modules. These modules are thoughtfully configured, comprising a bank of single-phase inductors. They are strategically connected both at the midpoint and the terminal point of the non-transposed line model within the confines of the Physical Laboratory of Electric Power Systems (LFSEP). The construction of the coils is executed with precision, meticulously adhering to the design values that have been diligently identified. These coils are subsequently incorporated into the two modules of the non-transposed transmission line models resident within LFSEP. To validate the electrical parameters of the inductive compensation modules and to assess their operational efficacy, rigorous steady-state tests are undertaken. These tests serve as the cornerstone for a comprehensive comparative analysis, ultimately culminating in the formulation of substantive conclusions regarding the practical implementation of this sophisticated equipment within the laboratory environment.
