Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wind speed variations are accounted for by monitoring and making comparisons only at the same wind speeds, then measurement precision improves, but device complexity increases and the method becomes overly complicated
Solution Approach 1:
The patent uses a comparison wind power installation that is identical to the test installation, creating a copy that serves as a reference. This copy allows the test installation to be evaluated under varying wind conditions without requiring complex normalization, as both installations experience the same environmental factors simultaneously.
Solution Approach 2:
The comparison wind power installation acts as an intermediary reference system. Instead of directly correcting for wind speed variations through complex monitoring and selection procedures, the comparison installation provides a baseline that naturally accounts for environmental variations, simplifying the assessment process.
2Measurement precision
If extensive simulation tools are used to remove wind speed variations and assess changes, then measurement precision improves, but loss of time increases and real-world validation is delayed
Solution Approach 1:
The patent creates a physical copy (comparison wind power installation) that replicates the test installation's characteristics. This physical replica allows simultaneous real-world operation under identical environmental conditions, providing immediate validation without requiring time-consuming simulations.
Solution Approach 2:
The comparison wind power installation self-corrects for environmental variations by experiencing the same wind conditions as the test installation. The system naturally provides its own reference data, eliminating the need for external simulation tools to compensate for environmental factors.
3Productivity
If component parts are changed to optimize wind power installation performance, then productivity improves, but difficulty of detecting and measuring increases due to wind speed variations and other influencing factors
Solution Approach 1:
The comparison wind power installation serves as an identical reference copy that experiences the same environmental conditions. By comparing the test installation's performance changes against this unchanged reference copy, the difficulty of detecting performance changes is eliminated, as environmental variations affect both installations equally.
Solution Approach 2:
The system continuously monitors and compares performance data from both installations, providing real-time feedback on the effect of component changes. This feedback mechanism isolates the impact of modifications from environmental variations, making performance detection straightforward and reliable.

AI summary
The present disclosure relates to a method for assessing a wind power installation, wherein a comparison is made between a test wind power installation and a comparison wind power installation for assessment purposes, comprising the steps of: synchronously operating the test wind power installation and the comparison wind power installation in an adjustment interval in an adjustment mode, in which the test wind power installation and the comparison wind power installation have matching operating settings, synchronously recording performance data relating to both wind power installations in each case in the adjustment interval in the adjustment mode, modifying the test wind power installation and/or the comparison wind power installation in a modification step such that the test wind power installation and the comparison wind power installation differ from one another, synchronously operating the test wind power installation and the comparison wind power installation, which differ from one another, at least in a comparison interval in a comparison mode, synchronously recording performance data in the comparison mode, and evaluating the performance data recorded in the adjustment mode and comparison mode in an evaluation step.
