SOLAR POWERED WATER PUMPING SYSTEM WITH PHOTOVOLTAIC SYSTEM THAT TRACKS A MAXIMUM POWER POINT |
摘要 |
A system and a method provide a photovoltaic system which regenerates the output characteristics of the photovoltaic at different ambient condition with high precision under all environmental conditions. The photovoltaic system includes a photovoltaic array, a buck/boost converter, a DC link capacitor to connect the buck/booster converter to a load/inverter, an adaptive network-based fuzzy inference maximum power point tracking controller, a voltage control loop, a proportional integral controller to maintain the output voltage of the photovoltaic array to the reference voltage by adjusting the duty ratio of buck/boost converter. |

1. A solar powered water pumping system powered by a photovoltaic system that tracks a maximum power point, comprising:
a photovoltaic array that generates a varying DC output voltage and current depending on one or more weather conditions; a buck/boost converter to step down/step up of the output voltage from the photovoltaic array; a DC link capacitor to connect the buck/booster converter to a load/inverter, wherein the load/inverter provides a grid output of the photovoltaic system; an adaptive network-based fuzzy inference maximum power point tracking controller to generate a reference voltage; a voltage control loop to compare the output voltage of the photovoltaic array to the reference voltage, and a proportional integral controller to maintain the output voltage of the photovoltaic array to the reference voltage by adjusting the duty ratio of buck/boost converter, and a pump powered by the current generated by the photovoltaic array. |
