Method and system for offshore wind power operation and maintenance decision simulation

Abstract

The invention provides a method and system for offshore wind power operation and maintenance decision simulation, and the method comprises the steps: A, building a bottom-layer fault database which stores fan set fault statistical data, wherein the fault data information stored in the bottom-layer database is divided according to grades; b, according to the information of the wind power plant and the bottom layer fault database, discretizing and randomizing the fault data information at each time point according to the occurrence probability and frequency of the fault data information; and C, performing combined operation and maintenance simulation on each fault according to a time sequence under the condition of conforming to the sea-going limitation, and obtaining an optimal logic strategy of combined operation and maintenance by taking the comprehensive optimization of the operation and maintenance cost and the power generation loss condition as a principle. According to the invention, the method is beneficial to the obtaining of an optimized guidance planning scheme for offshore wind power offshore operation and maintenance.

Description

technical field [0001] The present invention relates to the technical field of offshore wind power, in particular to a method and system for simulation simulation of offshore wind power operation and maintenance decision-making. Background technique [0002] The explosive growth of domestic offshore wind power, the high cost of offshore wind power operation and maintenance, and the power loss caused by downtime failures have a huge impact on the entire wind farm, leading to increasing requirements for lean planning of offshore wind power operation and maintenance by developers. However, since my country’s offshore wind power industry started late compared with Europe, the operation and maintenance years of the projects that have been put into production are not long, the overall operation and maintenance level is not high, and there is a lack of overall offshore wind power operation and maintenance simulation system, mainly in the following areas: 1) Information such as wind,...

Problems solved by technology

However, since my country’s offshore wind power industry started late compared with Europe, the operation and maintenance years of the projects that have been put into production are not long, the overall operation and maintenance level is not high, and there is a lack of overall offshore wind power operation and maintenance simulation system, mainly in the following areas: 1) It is impossible to effectively grasp and apply information such as wind, wave, current, tide, weather, visibility, extreme weather conditions, etc.

The current offshore wind power operation and maintenance has insufficient grasp and application of information such as wind, waves, currents, tides, weather, visibility, and extreme weather conditions. Going out to sea but encountering over-limit wind waves and extreme weather at sea poses a serious threat to the life safety of operation and maintenance personnel

2) Fault statistics for various faults of offshore wind power are still insufficient

Due to the limited production period, the offshore wind power industry has not yet formed a comprehensive and systematic fan fault database for a certain type of wind turbine of a certain complete machine manufacturer, and there is still great uncertainty about the time required for fault repairs, costs, preparations for going to sea, etc. characteristics, making it difficult to truly realize lean planning for the combined operation and maintenance of offshore wind power

3) The research on the logic and strategy of offshore wind power combined operation and maintenance lags behind
