Triggered Event Data Buffering in Renewable Power Plants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wind power generators lack an efficient mechanism to log data from both internal and external events in wind power plants, limiting the data collection to local occurrences and missing crucial information for comprehensive analysis.
Innovation Solution
A centralized data collection system with a temporary and permanent data store, along with a processor, that receives data from multiple sources within the power plant and stores it temporarily, and upon receiving a trigger signal, transfers relevant data to the permanent store for comprehensive analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional controllers log data only in response to events within individual generators, then storage costs are reduced, but the quantity and quality of data captured for external events is insufficient
Solution Approach 1:
A temporary data store acts as an intermediary component between multiple generator controllers and the permanent storage system. This mediator receives and buffers data streams from multiple sources, allowing the system to capture comprehensive data from external events without requiring each controller to independently log all possible data, thus increasing data quantity while managing system complexity
Solution Approach 2:
The temporary data store serves multiple functions: it receives data from multiple generator controllers, buffers data streams, triggers data transfer based on event detection, and manages data routing to permanent storage. This multi-functional component enables the system to handle external events comprehensively without proportionally increasing overall system complexity
2Reliability
If all data from multiple generators is stored permanently, then data quality for analysis is improved, but storage costs increase
Solution Approach 1:
The temporary data store pre-buffers data from multiple generators before permanent storage is required. This preliminary action ensures that when an external event occurs, all relevant data is already available and can be selectively transferred to permanent storage, guaranteeing data quality for analysis while avoiding the cost of permanently storing all possible data
Solution Approach 2:
The system selectively transfers only relevant data from the temporary data store to permanent storage based on trigger conditions. Data that is not associated with external events remains in temporary storage or is discarded, while critical event-related data is recovered and preserved permanently. This selective approach maintains high data quality for analysis while minimizing permanent storage requirements and costs

AI summary
Aspects of the present invention relate to a data collection system for a renewable energy power plant comprising a plurality of renewable energy generators. The system comprises a temporary data store in communication with the generators. The temporary data store is configured to: receive a stream of data from at least two of the generators; and temporarily store the received data. The system comprises a permanent data store for storing data for subsequent analysis. The system comprises a processor in communication with the temporary and permanent data stores and a plurality of trigger sources. The processor is configured to, in response to receiving a trigger signal from one of the plurality of trigger sources, cause temporarily-stored data from the temporary data store to be stored in the permanent data store.
