Problems solved by technology
[0003] However, because offshore wind power generation equipment needs to be installed on the sea for wind power generation work, it is difficult to fix it, so floating power generation equipment is often used for power generation
However, in order to obtain the maximum wind energy, the yaw system of offshore wind power generation equipment needs to adjust the angle of the fan to align with the wind direction according to the change of wind direction. After the angle of the fan changes, the gravity of the entire suspension base will be unstable, which will seriously affect the stability of the wind turbine. and security

The invention discloses a suspension type offshore wind generating set. The suspension type offshore wind generating set comprises a tower, a fan and a yaw system and further comprises a suspension frame installed at the bottom end of the tower, a balance adjusting system is arranged in the suspension frame, and the suspension frame is fixed to a seabed through an anchor chain; the suspension frame comprises three suspension cylinders which are vertically arranged, the three suspension cylinders are distributed in a regular triangle shape, and two adjacent suspension cylinders are connected through a fixing rod; the tower is vertically connected to the top end of one suspension cylinder; and the balance adjusting system comprises a balance sensing module, a control module, a water feeding and discharging module and an inter-cylinder water flowing adjusting module. When the yaw system adjusts the angle of the fan according to the change of the wind direction to cause the change of the gravity center of the whole offshore wind generating set, the balance sensing module collects gravity center data of the suspension frame, and the control module controls the water feeding and discharging module and the inter-cylinder water flowing adjusting module to adjust the change of the water level in three suspension cylinders according to the gravity center data, so that the gravity center of the whole offshore wind generating set is kept stable.
Description
technical field [0001] The invention relates to the technical field of offshore wind power generation, in particular to a floating offshore wind power generating set. Background technique [0002] Offshore wind energy resources are abundant and stable, and global wind power development is showing a trend of shifting from land to offshore. The principle of wind power is to use the wind force to drive the windmill blades to rotate, so as to promote the generator to generate electricity. Therefore, the local wind speed of the wind farm has a great influence on the power generation. Compared with onshore wind power, offshore wind power has abundant and stable resources, large grid capacity in coastal areas, and good wind power access conditions, so offshore wind power has more advantages. The grid connection of offshore wind power consists of two parts: (1) offshore wind turbines are connected to offshore substations through 33KV or 66KV submarine cables; (2) offshore substatio...
