The invention relates to a device used within an installation for monitoring and controlling the parameters of a low power wind turbine group. According to the invention, the device consists of a module () for adapting the electrical voltage and current signals and of a processing module which runs on a computing system (), where the adapting module () consists, in its turn, of a submodule () having the function of galvanic separation, consisting of two modules () for converting the signals, namely a voltage and a current signal, and of a module () for adapting the signals used for the conversion of the voltage and current signals into signals of 0...1 V which are transmitted to the computing system () which, by means of an acquisition module (), consisting of a sound card or a similar device, converts the received analogue signals into digital signals and transmits them to a processing module () which carries out the conditioning, correction and extraction of the parameters of interest, such as: the rotation speed of the wind turbine group, the voltage at the generator terminals or the supplied power, which may be stored or viewed by means of an interface () or are input parameters into a control submodule (), in order to regulate the power of the wind turbine group or to protect the same. |
