Detection and evaluation system for corrosion state of floating type offshore wind power mooring system

Abstract

The invention discloses a corrosion state detection and evaluation system for a floating type offshore wind power mooring system, which is characterized in that the mooring system is divided into a plurality of areas, and each area is provided with a detection device; each detection device is used for acquiring data of a corrosion state reference object in a corresponding area and transmitting the data to the field acquisition instrument, the data transfer station and the data analysis center; the corrosion state reference object comprises seawater temperature, dissolved oxygen, seawater flow velocity, sacrificial anode protection potential and protection current density; the corrosion state evaluation system is used for carrying out data preprocessing on data detected by the detection device; the artificial neural network model corresponding to each region evaluates the corrosion degree of the current region based on the preprocessed data; according to the influence of the partial corrosion degree on the overall corrosion state, the proportion weight of the evaluation result of the sub-region in the corrosion state evaluation of the mooring system is determined according to the grey correlation degree, namely the correlation degree of the sub-region and the overall mooring system; therefore, the corrosion state of the floating type offshore wind power mooring system is detected and evaluated.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, and mainly relates to a detection and evaluation system for the corrosion state of a mooring system of a floating offshore wind power basic platform. Background technique [0002] Offshore wind power is rich in resources, has high utilization hours of power generation, does not occupy land, and is suitable for large-scale development, while offshore wind energy resources in deep seas are more abundant than those in offshore areas, and the development prospects are broader. For deep-sea offshore wind power, fixed infrastructure is no longer applicable, and floating infrastructure is generally used. Floating offshore wind power basic platforms can be mainly divided into three types: single-column (Spar), semi-submersible (Semi-submersible) and Tension Leg Platform (TLP). [0003] The mooring system of the single-column foundation platform usually adopts the catenary type, and the moori...
