  • Control system for wind farms with aerogenerations provided with modular converters
    Patent number: 8680702
    Abstract: A control system (50, 100) is for wind power plants including aerogenerators (10) provided with DC modular converters (40). The control system (50, 100) includes devices for receiving at least a voltage signal coming from a DC medium voltage line (MTDC) electrically connected to the converters (40) and a mechanical torque signal (CRIF) produced by the aerogenerators (10) and controls AC-DC conversion modules (40a?-40a??) of the plant. The modules have electronic devices driven by impressed voltage and producing on their outputs a respective partial continuous voltage (Vdci). For each aerogenerator (10) there are 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 the partial continuous voltage (Vdci) at a constant value.
