Problems solved by technology
However, most of the models currently used for wind turbine condition monitoring research are developed for specific equipment, and are mostly used for unit design and static performance analysis, and often do not have real-time operation capabilities. Even if the dynamic performance of the unit can be simulated, the simulation accuracy is difficult to meet engineering standard
[0005] At the same time, the existing wind turbine status monitoring system is also relatively lacking in visual presentation capabilities

Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a digital twin system for wind power generation. Background technique [0002] As my country's large-scale offshore wind power construction plans have started successively and the warranty period of most wind turbines in operation has gradually exceeded or is approaching to exceed, the status quo of high failure rates and high operation and maintenance costs has attracted more and more attention. Compared with land wind turbines, offshore wind turbines will face a harsher operating environment and higher operation and maintenance costs. According to statistics, the maintenance cost of offshore wind turbines is at least twice that of onshore wind turbines, and the operation and maintenance costs are as high as 30% to 35% of economic income, of which about 25% to 35% are regular maintenance costs, and 65% to 75% are Subsequent maintenance costs. With the continuous ...
