FIELD: electric power engineering.
SUBSTANCE: wind farm for electric power supply to electric power supply network includes: at least two wind-driven power plants for electric power generation; wind farm DC network for transmission of electric power from wind-driven power plants to the connection point to the network; and installed between DC network of wind farm and point of connection to network of inverter, designed so that constant electric voltage of DC wind farm network to convert into alternating voltage for supply of electric power of wind-driven power plants to electric power supply network; at least one constant voltage converter for supplying electric power from at least one wind-driven power plant to wind farm DC network, wherein constant voltage converter comprises switching device and transformer with primary and secondary sides, wherein the primary side through the switching device is connected to the said at least one wind-driven power plant, and the secondary side through the at least one rectifier, in particular the rectifier, comprising several diodes, is connected to the wind farm DC network, and this constant voltage converter is intended to apply constant voltage with variable polarity to transformer primary side by means of switching device, so that DC voltage of said at least one wind-driven power plant is transformed from primary side to secondary side.
EFFECT: higher reliability during operation of wind-driven power plant in wind farm network.
