Wind Turbine Trip Event Data Acquisition System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wind turbine systems lack a comprehensive means to acquire and consolidate data from multiple subsystems, such as pitch control, power converter, and wind turbine controller, making it difficult to determine and analyze trip events effectively.
Innovation Solution
A system and method for acquiring and analyzing operational data from various wind turbine subsystems, utilizing a control system with microcontrollers, sensors, and a communication network to monitor and store data at high resolution, enabling detection and analysis of trip events by collecting and transferring data from pitch control, power converter, and yaw drive subsystems.

1Loss of information
If data is acquired from multiple subsystems separately, then data collection is simple, but comprehensive trip event analysis cannot be performed
Solution Approach 1:
The patent combines data acquisition from multiple subsystems (pitch control, power converter, wind turbine controller) into a single integrated system. The controller receives data from all subsystems and consolidates them for comprehensive trip event analysis, eliminating the need for separate analysis of each subsystem and ensuring complete trip event data collection.
Solution Approach 2:
The controller serves multiple functions: it acts as the wind turbine controller, pitch control interface, and power converter interface simultaneously. This multi-functional design allows a single device to acquire and process data from all subsystems, reducing overall system complexity while ensuring comprehensive data collection for trip event analysis.
2Measurement precision
If high-resolution data is stored continuously, then trip event analysis precision is improved, but data storage requirements increase
Solution Approach 1:
The system continuously stores operational data at high resolution in advance of potential trip events. This preliminary data acquisition ensures that when a trip event occurs, the high-resolution data is already available for immediate analysis, eliminating the need for post-event data collection and ensuring precise trip event characterization.

AI summary
A system and method is provided for acquiring operational data from a wind turbine (100) and analyzing trip events. One or more data buffers (412) can store operational data obtained from at least one control subsystem. A trip event detection system (410) can be connected to the data buffers (412), and monitors for the occurrence of a trip event. The data stored in the data buffers (412) can be transferred to a trip log buffer (450).
