Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind energy systems face reduced reliability and operability due to the arbitrary selection of wind turbines for power reduction, leading to unnecessary deactivation of more reliable turbines and potential turbine failure.
Innovation Solution
A wind energy system with a control device that determines performance identifiers for each turbine based on operating and historical parameters, allowing for the selective deactivation of turbines with lower performance, ensuring that more reliable turbines continue to operate during power reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wind turbines are arbitrarily selected for power reduction, then the power grid specification can be met, but the reliability and operability of the wind energy system decreases
Solution Approach 1:
The patent changes the selection criterion from arbitrary or simple power-based selection to a comprehensive performance identifier that includes multiple parameters such as availability, capacity factor, and operational status. This parameter transformation enables differentiated selection of wind turbines for deactivation, prioritizing those with lower performance metrics to maintain system reliability while meeting power reduction requirements.
2Reliability
If wind turbines with lower operability are deactivated, then the reliability of remaining turbines is maintained, but the complexity of selection and control increases
Solution Approach 1:
The control device pre-calculates and stores performance identifiers for all wind turbines based on their historical and current operational data. This preliminary action enables rapid decision-making during power reduction events, as the selection criteria are already established and ready for immediate application without requiring complex real-time calculations during the deactivation process.
Solution Approach 2:
The patent replaces complex mechanical assessment and manual selection processes with an automated electronic control system that calculates performance identifiers and automatically selects turbines for deactivation. This substitution of mechanical/manual systems with electronic automation reduces operational complexity while improving selection accuracy and reliability.
3Productivity
If only actual power values are considered for turbine selection, then the power reduction target can be achieved quickly, but the long-term operability of the system deteriorates
Solution Approach 1:
The control device pre-calculates and stores performance identifiers for all wind turbines based on their historical and current operational data. This preliminary action enables rapid decision-making during power reduction events, as the selection criteria are already established and ready for immediate application without requiring complex real-time calculations during the deactivation process.
