Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing SCADA systems for wind turbines require shutdown for software updates or modifications, leading to downtime and potential damage due to lack of monitoring and control during the process.
Innovation Solution
A wind turbine management system that allows for real-time formula creation, modification, and application without shutting down the system, using a controller with memory storage and communication capabilities to select and apply formulas based on operational data, enabling continuous monitoring and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new or replacement software is installed to modify formulas in SCADA system, then the SCADA system can calculate additional or modified parameters, but the system must be in non-operating mode causing downtime and loss of monitoring capability
Solution Approach 1:
The patent segments the SCADA system into multiple independent controller units (first controller, second controller, third controller) that can operate autonomously. This allows formula modifications to be applied to individual controllers without shutting down the entire system, maintaining monitoring capability while enabling adaptability.
Solution Approach 2:
The patent introduces a communication network as an intermediary that enables formula updates to be transmitted and applied to individual controllers without requiring system shutdown. This intermediary allows the system to maintain operation while accepting modifications.
2Adaptability or versatility
If software is updated to implement new formulas, then additional parameters can be calculated, but the system experiences downtime during the update process
Solution Approach 1:
The patent enables continuous operation of the SCADA system by allowing formula updates to be applied to individual controllers without shutting down the system. The monitoring and calculation functions continue uninterrupted in other controllers, maintaining continuous useful action.
Solution Approach 2:
The patent implements dynamic formula updates where controllers can independently receive and apply new formulas at different times without synchronized shutdown. This dynamic approach allows the system to adapt continuously rather than in discrete停机 periods.
3Adaptability or versatility
If updated software components are installed to apply new formulas to specific wind turbines, then targeted parameter calculation is enabled, but system complexity and update requirements increase
Solution Approach 1:
The patent segments the formula application capability by controller and wind turbine, allowing selective updates to specific controllers that monitor particular turbines. This granular segmentation enables targeted formula application without requiring system-wide updates.
Solution Approach 2:
The patent implements local quality by allowing different controllers to have different formulas applied based on their specific monitoring requirements. Each controller can be independently configured with formulas appropriate for its specific wind turbines, rather than uniform system-wide formulas.

AI summary
A controller (202) for use in monitoring at least one operating wind turbine (100,308) is provided. The controller is communicatively coupled to the at least one operating wind turbine, to a server sub-system (208), and to a user interface device (304). The controller is configured to receive operational data from the at least one operating wind turbine, select at least one formula based on the received operational data, wherein at least one of a predetermined formula is selected, a formula is selected via the user interface device, and a formula is selected via the server sub-system, determine at least one site level parameter (406) using the at least one selected formula, and transmit at least one of operational data, the at least one selected formula, and the determined parameter to the server sub-system.
