Offshore anti-typhoon wind power generation system

Abstract

The invention discloses an offshore anti-typhoon wind power generation system. The offshore anti-typhoon wind power generation system consists of a terminal processor, a control device and power generation fans. The power generation fans are connected with the upper end of a buoy through a connecting rod, the lower end of the buoy is fixedly connected with a counterweight block, the counterweightblock is used for stabilizing the buoy, and the control device is fixed on the upper part of the buoy. One end of a cable is connected to the buoy, and the other end of the cable is fixed on the seabed. A RF communication module of the control device receives instructions sent by the terminal processor and transmits the instructions to a core processor, meanwhile, a pressure sensor transmits pressure information of the wall surfaces of the generator fans to the core processor, after the core processor analyzes the processed information, water quantity in the buoy is controlled by a water inletand outlet device to change the water quantity in the buoy, and thus whole floating up and down can be realized to change the height position to cope with typhoon. The wind power generation system can automatically assess the threat of the typhoon to the fans and take protective measures to the fans according to real-time meteorological information and geographical characteristics of the local sea area, and takes into account the efficiency of power generation.

Description

Technical field [0001] The invention relates to the technical field of wind power generation, in particular to an offshore typhoon wind power generation system. Background technique [0002] As the pace of global economic development accelerates, energy issues have become a worldwide problem, and the exploration and development of new energy alternative products has become the research direction of experts in related fields from all over the world. The development and utilization of offshore wind energy has received more and more attention. Offshore wind energy has the characteristics of saving land resources and extensive wind energy resources. However, in the coastal zone, the challenge of nature cannot be avoided-typhoon. The unique structure of the wind turbine makes it easy to be damaged in a typhoon, and its consequences are very serious. Not only can it not use the huge energy of the typhoon, it will also cause huge economic losses. my country is rich in wind energy res...

Problems solved by technology

The measures to strengthen the bearing of components all require to increase the stiffness of the blade structure and the main shaft moment. The basic requirement is to further improve the mechanical properties of the fan, which will cause an increase in the mass load during structural design, and will further lead to an increase in manufacturing, transportation and installation costs.

The mechanical braking of the drive shaft can reduce typhoon damage through the brake, but the braking state will cause the transmission gear to bear the constantly changing torque load, which may cause hidden dangers such as fatigue fracture of the transmission gear

When a typhoon comes, feathering the wind blades can protect the blades to a certain extent, but the effect is limited in practice; another way of thinking is to disassemble the huge blades or throw out the brake body of the blades before the typhoon comes. This method is time-consuming and labor-intensive, requiring a large amount of special equipment, and time and cost are not allowed
