Wind electricity generation system of the type that has an accumulator, and device to control the charge and discharge of the accumulator

摘要

A device for controlling the loading and unloading of an accumulator (4) in a wind electricity generation system, of the type that has an accumulator with a wind electricity generator (1) powered by wind energy, to generate energy with which It will power an electrical circuit, and where the accumulator (4) for loading / unloading a part of the energy produced by the wind electricity generator (1), comprises the following: an instant response detection portion (11), for sequentially detect, as an instant response element, an instantaneous value of an amount of an energy produced by the wind electricity generator (1); a variation calculation portion, to calculate the variation per unit of time of the instant response element that detects the instant response detection portion (11); a charge and discharge control portion (14), to control the charge and discharge of the accumulator (4), depending on the fluctuation of the instant response element detected by the instant response detection portion (11); a storage portion of the pattern information (15), for storing various kinds of pattern information related to an instant response control region representing the capacity of the accumulator (4) to be assigned to the control of the loading and unloading of the accumulator, depending on the fluctuation prevailing in the instant response element and a portion of pattern information selection (16), to select one of the various kinds of pattern information (A, B, C) stored in the portion of storing the pattern information (15) and applying the pattern information to the control of the loading and unloading of the accumulator by means of the loading and unloading control portion (14), according to the variation per unit of time of the instant response element , whose calculation is in charge of the calculation portion of the variation (13).
