Offshore wind plant operation and maintenance scheme generation method and device

Abstract

The invention provides an offshore wind plant operation and maintenance scheme generation method, device and equipment and a storage medium. The method comprises the following steps: acquiring basic data of an offshore wind plant, wherein the basic data of the offshore wind power plant comprises marine meteorological condition data, adjustable resource data, wind power plant fault data and unit cost data; constructing an offshore wind power operation and maintenance constraint condition according to the marine meteorological condition data, the adjustable resource data and the wind power plant fault data; constructing a mathematical optimization model based on the offshore wind power operation and maintenance constraint conditions and a preset objective function; and inputting the unit cost data into the mathematical optimization model for measurement and calculation, and screening and outputting a plurality of candidate operation and maintenance schemes according to a measurement and calculation result. The operation and maintenance plan scheme can be automatically scheduled and generated according to the characteristics of the operation and maintenance task of the offshore wind plant, so that the operation and maintenance efficiency of the offshore wind plant is improved.

Description

technical field [0001] The present invention relates to the technical field of offshore wind farms, in particular to a method, device, equipment and storage medium for generating an operation and maintenance scheme of an offshore wind farm. Background technique [0002] The offshore wind power industry is developing rapidly. At present, more than ten offshore wind farms in a certain province are under construction, and will be connected to the grid for power generation in the near future. In the future, the province's offshore wind power industry will shift from the peak period of construction to the peak period of operation and maintenance. The maintenance and repair market of offshore wind farms will show a trend of low first and then high. By 2025, the market space for maintenance and repair services will reach 3 billion yuan per year Scale, the annual compound growth rate is about 50%. Due to the difficulty and high cost of offshore wind power maintenance and repair, an...

AI Technical Summary

Problems solved by technology

The maintenance of offshore wind turbines is limited by the sea conditions, and often the wind turbines cannot be maintained in a timely and effective manner, resulting in a certain amount of power loss, which indirectly increases the offshore wind farm. These factors make the operation and maintenance cost of offshore wind power about 2-4 times that of land Even higher operating and maintenance costs

[0005] 2. The failure rate of offshore wind turbines is higher:

[0006] Offshore wind farms have high average wind speed and high annual utilization hours, but at the same time, offshore wind farm equipment is more susceptible to harsh natural conditions such as salt spray, typhoon, sea waves, lightning, and ice loads. The components of wind turbines fail quickly and the service life of components is shortened.

In addition, offshore wind farms are far away from the shore, which is not convenient for frequent daily inspections. Therefore, the failure rate of offshore wind turbine equipment is significantly higher than that of onshore wind farms.

According to statistics, the annual average availability rate of offshore wind turbines is only 70% to 90%, which is far lower than the 95% to 99% availability rate of onshore wind turbines.

[0007] 3. Poor accessibility of offshore wind turbines:

[0009] At present, the operation and maintenance plan of most offshore wind farms is manually scheduled and scheduled. This method is time-consuming, laborious and inefficient, and the obtained scheduling plan is often not optimal, resulting in low operation and maintenance efficiency.
