RESUMEN
En este trabajo se presenta el diseño del controlador Proporcional Integral (PI) de un Filtro Activo de Potencia (FAP) en derivación para mejorar la calidad de la energía de la red eléctrica en conexión con un inversor fotovoltaico. El diseño del controlador PI se llevó a cabo con un método basado en la compensación de corrientes armónicas, el modelo de FAP que considera el bus de CD y un inversor en fuente de voltaje, así como la respuesta dinámica de un sistema de segundo orden en su forma estándar. A pesar de que en la red eléctrica se consideraron cargas no lineales, inductivas y desbalanceadas, el método utilizado permitió una corrección efectiva de los armónicos de corriente, reduciéndolos a menos de l 4%, y garantizar un factor de potencia unitario. Además, e ste método contribuye a una mejor comprensión del proceso de diseño del controlador PI. La efectividad del FAP en derivación con controlador PI fue validada mediante simulaciones exhaustivas en el entorno de MATLAB/Simulink.
Palabras Clave: Filtro activo de potencia en derivación, controlador Proporcional Integral, calidad de la energía.
ABSTRACT
This paper presents the design of the Proportional Integral (PI) controller of a shunt Active P ower Filter (APF) to enhance the power quality of the power grid in connection with a photovoltaic inverter. The PI controller design was performed using a method based on harmonic current compensation, the FAP model considering the DC bus and a voltage so urce inverter, and the dynamic response of a second-order system in its standard form. Although non-linear, inductive, and unbalanced loads were considered in the electrical network, the method effectively corrected the current harmonics, reducing them to less than 4% and guaranteeing a unity power factor. In addition, this method contributes to a better comprehension of the PI controller design process. The effectiveness of the shunt FAP with PI controller was validated by extensive simulations in MATLAB/S imulink environment.
Keywords: shunt active power filter, integral proportional controller, power quality.
