The invention discloses a three-machine-head wind generating set and an installation method. The three-machine-head wind generating set comprises machine heads, a tower frame, a rotary supporting arm and an inhaul cable. Each machine head is composed of a cabin and an impeller, and the number of the machine heads is three. The tower is divided into a first tower and a second tower, the bottom of the first tower is connected with the foundation, and the top of the first tower is connected with the bottom of the second tower through a transition structural member. The first machine head is arranged at the top of the second tower; the rotary supporting arm is arranged outside the transition structural part and at the top of the first tower; and the second machine head and the third machine head are arranged on the rotary supporting arm. The inhaul cable is divided into an inclined inhaul cable and a horizontal inhaul cable, and the inclined inhaul cable is connected with the first machine head and the second machine head and is connected with the first machine head and the third machine head. And the horizontal transverse inhaul cable is connected with the second machine head and the third machine head. According to the scheme, a supporting structure composed of the tower and the slewing bearing arm effectively bears gravity loads and aerodynamic loads, and the economical efficiency of a high-capacity unit is improved.
Description
technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a three-head wind power generator set and an installation method. Background technique [0002] Cost is the bottleneck of global wind power development, and the most effective way to solve the cost problem is to increase the unit size (increase the capacity of a single unit). The continuous development of offshore wind power projects has made the large-scale unit an inevitable development trend. With the increase of the capacity of the unit, the upgrade of the traditional single-blade wind turbine encounters more and more severe challenges. The load of the unit increases sharply, and the super-long, super-heavy blades and super-large torque give various components in the unit (such as the pitch actuator, Supporting structures, etc.) pose many challenges in terms of design, manufacture and installation. For example, if a unit of more than 10 megawatts c...
