Single column maritime wind power generation device with circumferential stabilizing column

Abstract

The invention provides a single column maritime wind power generation device with a circumferential stabilizing column, and belongs to the technical field of ocean energy resource utilization. The single column maritime wind power generation device with the circumferential stabilizing column comprises a wind power generation set, a single column base, the circumferential stabilizing column, a supporting structure, a berthing system and a fixed ballast system; the wind power generation set is fixed on the single column base; the circumferential stabilizing column is fixed at the periphery of the single column base; both ends of the supporting structure are connected with the circumferential stabilizing column and the single column base respectively; the middle part and the bottom of the single column base are connected with the berthing system and the fixed ballast system respectively; and the berthing system is connected with the seabed. By arranging the circumferential stabilizing column, a larger waterline plane inertial moment can be obtained in a smaller waterline plane area; meanwhile, due to the low gravity center of the single column base, the stability requirement is met and the high water power performance is gained; therefore, a stable, economic and flexible floating base is provided for the wind power generation set, so the single column maritime wind power generation device with the circumferential stabilizing column is particularly applicable to deep water regions of the open sea.

Description

technical field [0001] The invention relates to a device in the technical field of marine energy utilization, in particular to a single-column offshore wind power generation device with a circumferential stabilizing column. Background technique [0002] With the rapid development of the world economy, human demand for energy is increasing day by day. However, due to its non-renewability, the reserves of conventional energy are decreasing day by day. At the same time, the environmental pollution caused by the use of conventional energy has become a severe challenge for human survival and development. At present, relevant institutions around the world are actively developing and utilizing renewable clean energy. There are abundant wind energy resources and vast flat areas in the sea, making offshore wind power technology a hot spot for application in recent years. [0003] my country's offshore wind energy resources are expected to reach 750 million kilowatts, which is three...

Problems solved by technology

Norway successfully installed and operated a "Hywind" single-column wind power generation device in 2009. The rated power of the fan is 2.3MW, and the first method is used to obtain stability. The draft is 100m and the drainage volume is 5300m. 3 , with an investment cost of up to NOK 400 million

If this technology is to be used to realize large-scale power generation at sea, the investment cost is high and the economic performance is poor; in addition, this technology is not suitable for sea areas with a water depth less than 100m, and the installation technology is difficult. A new type of floating foundation with better economy
