Wind Turbine Evaluation Device for Early Malfunction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind turbine monitoring systems rely on large tolerance ranges for temperature measurements, leading to late detection of malfunctions, as high or low temperatures may not necessarily indicate a fault, especially in varying environmental conditions.
Innovation Solution
A method and system that utilize an evaluation device to receive and analyze data from multiple wind turbines or farms, allowing for early detection of deviations in operating parameters by comparing with reference values from similar conditions, and issuing control commands or event messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large tolerance ranges are used for temperature measurements, then false alarms are reduced, but malfunction detection is delayed
Solution Approach 1:
The system continuously monitors temperature measurements and compares them against dynamically updated reference ranges from multiple wind turbines. When a deviation is detected, the system provides feedback through event messages and control commands, enabling continuous adaptation and early detection of malfunctions while maintaining reliable operation during normal temperature variations.
Solution Approach 2:
The evaluation device serves multiple functions: it collects temperature data from multiple wind turbines, establishes reference ranges, detects deviations, generates event messages, and outputs control commands. This multi-functional approach enables the system to both reduce false alarms and detect malfunctions early by leveraging data from the entire wind farm rather than individual turbines.
2Measurement precision
If tolerance ranges are made small to detect malfunctions early, then detection sensitivity increases, but false alarms increase
Solution Approach 1:
The system merges temperature data from multiple wind turbines to establish a comprehensive reference range. By combining measurements from multiple turbines operating under similar environmental conditions, the system achieves high detection sensitivity while maintaining reliability, as the aggregated data reflects normal operational variations across the entire wind farm.
Solution Approach 2:
The system performs preliminary actions by continuously collecting and analyzing temperature data from multiple turbines to establish accurate reference ranges before malfunctions occur. This preliminary data gathering and analysis enables the system to detect deviations with high sensitivity while distinguishing them from normal operational variations, thereby reducing false alarms.
3Measurement precision
If data from multiple wind turbines is collected and compared, then early detection of deviations is enabled, but system complexity increases
Solution Approach 1:
The evaluation device acts as an intermediary between multiple wind turbines and the control system. It centralizes data collection from all turbines, performs reference range establishment and deviation detection, and outputs consolidated control commands or event messages. This intermediary approach enables precise multi-turbine comparison while managing system complexity through centralized processing.
4Reliability
If centralized evaluation of multiple turbines is implemented, then early malfunction detection is achieved, but control system complexity increases
Solution Approach 1:
The control system is segmented into independent functional modules within the evaluation device: data collection from multiple turbines, reference range establishment, deviation detection, event message generation, and control command output. This segmentation enables centralized evaluation of multiple turbines for early malfunction detection while managing complexity through modular, independently manageable components.
