摘要
A control system (50, 100) for wind power plants, the wind plants comprising aerogenerators (10) provided with DC modular converters (40); the control system (50, 100) comprises means for receiving at least a voltage signal coming from a DC medium voltage line (MTDC) electrically connected to said converters (40) and a mechanical torque signal (CRIF) produced by the aerogenerators (10) and controls a plurality of AC-DC conversion modules (40a' -40a' ' ' ' ) of said plant, having inside themselves a plurality of electronic devices driven by impressed voltage and producing on their outputs a respective partial continuous voltage (Vdci); for each aerogenerator (10) there is a plurality of secondary control stages (100) and a single main control stage (50); each of the secondary control stages (100) supplies control signals to a respective AC-DC conversion module (40a' -40a' ' ' ' ) and is designed to keep said partial continuous voltage (Vdci) at a constant value.
