Problems solved by technology

The existing offshore platform power system structure optimization design method collects the daily data records of platform operators as the basic data for structure optimization. The data collection is difficult and the integrity is low, and it is impossible to describe the daily operation characteristics of the offshore platform power system in detail. Larger adjustments to equipment and system connections require complex data collection processes to be performed again, making maintenance and optimization difficult and costly to optimize
At the same time, since the collected data itself is refined to the device level and does not directly reflect the operating characteristics of each platform node, it is necessary to abstract each platform into nodes and then perform structural optimization, which increases the complexity of structural optimization
