Problems solved by technology

[0005] In order to solve the various problems of the existing tower top yaw that the load is too large to cause the whole machine to be heavy, the present invention proposes a yaw tower section, which can reduce the weight of the tower, thereby reducing the cost of the whole machine, and at the same time It can also always ensure the balance of the bending moment on the tower during the yaw process, reducing the damage of the overturning moment

Abstract

The invention provides a yaw tower drum section, a tower drum and a wind turbine generator system. The yaw tower drum section comprises a rotary tower drum section, the tower drum section is connectedwith a fixing section through a yaw bearing, the rotary tower drum section and blades of the wind turbine generator system rotate at the same time, and the center of gravity of the rotary tower drumsection is located on the side, far away from the blade installing direction, of a core line. In the wind turbine generator system yaw process, balance of bending moment borne by the tower drum is guaranteed all the time, the harms of capsizing moment are reduced, and stable running of the system is guaranteed.

Description

technical field [0001] The present invention relates to a yaw tower section, and more particularly, to a wind power generating set and a tower of the wind generating set. Background technique [0002] A wind turbine is a device that converts wind energy into electrical energy, such as figure 1 As shown, the impeller assembly is connected with the generator 2 through high-strength bolts, and the impeller assembly is composed of hubs and blades 1 to realize the capture and transmission of wind energy; The absorbing part captures the wind energy and transfers the energy to the generator 2. The rotor part of the generator 2 is connected to the blade 1 through the shaft system, and the stator part of the generator 2 is connected to the base of the nacelle 3 to realize the conversion of wind energy into electric energy. The generator 2 converts the wind energy transmitted by the blade 1 into electrical energy, which is then transmitted to the grid. In order to capture wind ener...
