System for the electronic management of photovoltaic cells as a function of meteorology

摘要

The invention relates to a system for the electronic management of a photovoltaic generator, said system comprising a plurality of n static converters (11, 12, 13) connected in parallel, each converter (11, 12, 13) being electrically connected to at least one photovoltaic cell (10) of the generator. The number of converters connected is varied by varying the photovoltaic power, by comparing the generated power to thresholds P1, P2, . . . , Pn−1 after a time delay t. The invention also relates to a generator comprising said system and to the associated control method.

1. An electronic control system of a photovoltaic generator having at least one cell, the electronic control system comprising:
a plurality of n parallel coupled static converters, each of said plurality of static converters configured for being selectively coupled to at least one of the at least one cells of the photovoltaic generator, wherein a connection including a select number of said plurality of static converters is selected in accordance with a variation in photovoltaic power determined by comparing power generated by the at least one cells to power threshold values P1, P2, . . . Pn−1, the connection including i static converters of said plurality of static converters if a first connection condition corresponding to a measured power value between Pi−1 and Pi is satisfied, and the connection including each static converter of said plurality of static converters if a second connection condition corresponding to a measured power value greater than Pn−1 is satisfied, wherein the connection is made only after a delay time t if the corresponding first connection condition or the corresponding second connection condition is still satisfied.
