FIELD: power industry. ^ SUBSTANCE: wind-driven power plant includes a nacelle with rotor, generator, AC rectifier on generator side, AC rectifier on the mains side, and transformer; the above nacelle is arranged on the tower; besides, both of the above AC rectifiers on constant voltage side are electrically connected to each other, and at that, AC rectifier on the mains side is connected on alternating voltage side through transformer to infeed point of the mains receiving the energy. Each phase module of AC rectifier on the mains side includes upper and lower branches (T1, T3, T5; T2, T4, T6) of valves, which contains at least two electrically and in-series connected bipolar sub-systems, and AC rectifier on generator side and AC rectifier on the mains side are connected to each other on constant voltage side by means of DC cable. ^ EFFECT: wind power station consisting of multiple wind-driven power plants is designed and has flexible structure as to direct current; nacelles in each wind-driven power plant have smaller dead weight. ^ 14 cl, 9 dwg |
