Abstract

The invention discloses a multi-rotor wind power generation system with a tail rudder, which includes a lower tower 1, a slewing bearing 3 and a wind turbine, and also includes an upper tower 2, a beam 6 and a tail rudder 7, and the slewing bearing is arranged on the upper tower and the wind turbine. Between the lower towers, the lengths of the beams arranged on both sides of the upper towers are unequal, and are fixedly connected to the upper towers through one end of the beams respectively, and the wind turbine is fixedly connected to the top of the upper tower or/and the beams, and the wind turbine Including the wind wheel 4 and the nacelle 5, the number of wind turbines arranged on the longer beam is 0-10 more than the number of wind turbines on the shorter beam, and the tail rudder is connected with the upper tower, beam or/and nacelle through pin shafts. connect. The blade of the invention has long service life, small occupied area, low installation cost, low maintenance cost, good reliability, wide application range, cancels the slewing bearing or slewing driving device in the nacelle, and has automatic wind control, yaw and safety protection.

Description

technical field [0001] The invention belongs to the field of wind energy utilization and relates to a multi-rotor wind power generation system with tail rudders. Background technique [0002] With the global energy crisis and global environmental pollution intensifying, many countries are paying more attention to the research, development and utilization of clean and renewable energy. The Global Wind Energy Council pointed out that compared with other renewable energy technologies, wind power technology is more mature, its efficiency is higher, the industry has the best prospect, and its development and utilization growth rate is much higher than that of conventional energy. One of the fastest renewable energy technologies. [0003] The wind rotor is the core component that converts wind energy into mechanical energy, so the performance of the blade determines the performance of the wind turbine, and the safe and stable operation of the blade within the design life is very ...
