Wind Turbine Alarm Logging for Accurate Operational Data Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for monitoring and logging operational data of wind turbines often provide an inaccurate picture due to transmission errors, leading to incorrect allocation of power production value between manufacturers and operators, which deviates from the true operational state.
Innovation Solution
A method that involves sensors transmitting parameter values to a control system, which registers critical events and sets/reset alarms with corresponding IDs, and a monitoring system logs and timestamps these events to accurately track operational sectors' performance, ensuring reliable data reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If existing monitoring systems are used to log operational data, then data collection is automated, but transmission errors lead to inaccurate reporting of operational state
Solution Approach 1:
The system uses feedback by comparing the time counter data (which tracks actual operational time) with the logged alarm setting/reset times. When discrepancies are detected between these two independent data sources, the system identifies and corrects transmission errors in the alarm logging, thereby maintaining accurate operational state reporting while preserving automated data collection.
2Measurement precision
If alarm settings and resettings are logged to track operational state, then operational monitoring is enhanced, but transmission errors cause incorrect allocation of power production value
Solution Approach 1:
The time counter serves as an intermediary verification mechanism. It independently tracks the operational time of the wind turbine sector, providing a reference against which the logged alarm events can be validated. This intermediary data source enables detection of transmission errors in alarm logging without compromising the enhanced operational monitoring capability.
3Measurement precision
If time counter is used to track operational time, then accurate operational duration is recorded, but discrepancies with logged alarms indicate transmission errors
Solution Approach 1:
The system establishes a feedback loop where the time counter data is continuously compared with the logged alarm events. When discrepancies are detected (indicating potential transmission errors), the system uses the reliable time counter information to identify and correct the erroneous data, thereby maintaining both precise operational duration recording and data integrity.
