Control de filtros activos de potencia para la mitigación de armónicos y mejora del factor de potencia en sistemas desequilibrados

Abstract

La utilización, cada día mayor, de dispositivos electrónicos en sectores residenciales, comerciales e industriales ha traído consigo un aumento significativo de las perturbaciones que afectan la calidad de la forma onda (distorsión armónica) y por ende a la degradación de ésta. El origen del problema en este caso está en la demanda de corrientes altamente distorsionadas que al propagarse por la red provocan caídas de tensión con un alto grado de distorsión armónica, aumento de pérdidas en las líneas eléctricas, malfuncionamiento de equipos, etc. Las soluciones existentes tratan de evitar que estas corrientes se propaguen por la red o en su defecto limitar la emisión de perturba¬ciones de forma que no afecte a la inmunidad electromagnética de los equipos o instalaciones conectadas a la red eléctrica. En esta tesis doctoral se presentan las bases conceptuales para implementar un filtro activo de potencia de conexión en paralelo (FAPP) para compensar esta perturbación y se propone un nuevo algoritmo para la generación de la corriente de referencia que busca extender el espectro de aplicación de estos filtros bajo tensiones de suministro desequilibradas y/o distorsionadas. Adicionalmente, se ha diseñado y construido un prototipo de FAPP que permite entre otras cosas el poder implementar los distintos algoritmos presentados en la literatura y verificar las capacidades que tiene este dispositivo para compensar perturbaciones de corriente en tiempo real. _________________________________________________ The wide application of the non-linear loads and electronics equipment such as adjustable speed drives, compact fluorescent lamps and personal computers in residential, commercial and industrial buildings, is directly responsible for the marked increase in the level of harmonic distortion observed in today's electrical power networks, producing an important and undesirable harmonic pollution problem. To mitigate the adverse impact of harmonic currents in electrical systems, compensators for such non-linear loads are needed and the active power filters appear like the dynamic solution that best fits the compensation necessities. In this PhD Thesis, the conceptual bases for a shunt active power filter (SAPF) implementation are presented and a new current reference algorithm for the SAPF control is proposed. The algorithm calculates the current reference to compénsate harmonics in the load current, load unbalances and the power factor under unbalanced and distorted voltages. Finally, the feasibility of the hardware implementation for the proposed current reference algorithm and other controls is evaluated in an experimental setup.
