- Photovoltaic water pumping system for small power conventional AC pumpsPublication . Tangerino, Bruno Henrique Boschetti; Roman, Dionizio José Vargas; Leite, V.; Goedtel, Alessandro; Ferreira, Ângela P.; Batista, José; Maidana, WellingtonThe interest of photovoltaic (PV) water pumping systems with standard components is increasing as a low cost and independent solution over dedicated systems. However, one of the challenges of this alternative is the fact that small power systems to drive power pumps require a small number of PV modules and the PV string voltage is, usually, not enough to feed the frequency converter. This paper presents an approach to the drive, using a DC/DC converter with maximum power point tracking (MPPT). The overall system has been tested on a real experimental platform.
- Power converters control for photovoltaic water pumping systemPublication . Tangerino, Bruno Henrique Boschetti; Leite, Vicente; Goedtel, Alessandro; Ferreira, Ângela P.This work proposes solutions to challenges encountered in photovoltaic water pumping systems, such as the issue in the number of photovoltaic modules in low power systems, the maximum power point tracking and its implementation, as well as the pump control system. The maximum power point tracking is achieved via the addition of a step-up converter controlled by a proportional-integral controller. The system load is comprised by an induction motor, controlled by an open-loop scalar strategy. Simulations and real platform tests with solar radiance variation and variable number of photovoltaic modules were performed, validating the operation of the proposed solutions.
