Remote Wind Turbine Fault Reset via SCADA Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wind turbine control systems require manual intervention at the on-site SCADA system for resetting faults, leading to slow response times and increased downtime, especially when operators manage multiple wind farms remotely.
Innovation Solution
A computer-implemented method and system that allows for remote resetting of faulted wind turbines using a client device, such as a smartphone, by analyzing fault data, determining reset conditions, and authenticating users to transmit reset commands to the local SCADA system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual reset procedure is used at on-site SCADA system, then operator can reset the faulted wind turbine, but response time is slow and downtime is increased
Solution Approach 1:
The system enables self-service by allowing the wind turbine control system to automatically detect faults and execute reset procedures without requiring manual operator intervention. The control system autonomously monitors its own status and performs corrective actions, eliminating the need for operators to physically travel to each turbine for routine reset operations.
Solution Approach 2:
A remote interface system acts as an intermediary between the operator and the wind turbine control system. This intermediary enables operators to initiate reset commands remotely from a centralized location, eliminating the need for direct on-site manual intervention while maintaining operator control and oversight of the reset process.
2Productivity
If operator manages multiple wind farms individually, then each wind farm can be controlled, but response time across multiple farms is significantly decreased
Solution Approach 1:
The system merges multiple distributed wind farm control systems into a single centralized remote interface. This unified interface consolidates access to all wind farms, allowing operators to manage multiple facilities through one system rather than switching between individual SCADA systems, thereby significantly improving response time across the portfolio.
Solution Approach 2:
The remote interface system provides universal functionality by enabling a single operator to access and control multiple wind farms through one unified platform. The system performs multiple functions including fault detection, reset initiation, and monitoring across diverse locations, eliminating the need for separate control systems for each facility.
3Productivity
If remote reset capability is implemented, then response time is improved and downtime is reduced, but system complexity increases
Solution Approach 1:
The system incorporates feedback mechanisms that automatically monitor turbine status, detect faults, and determine reset eligibility. This feedback loop enables the system to intelligently decide when and how to execute reset procedures, automating complex decision-making processes that would otherwise require manual judgment, thereby improving efficiency without proportionally increasing operational complexity.
Solution Approach 2:
The system performs preliminary actions by pre-configuring reset procedures and pre-authorizing reset commands for different fault conditions. Before a fault occurs, the system establishes the framework for rapid response, so that when a fault happens, the reset can be executed immediately without requiring complex real-time decision-making or system configuration.

AI summary
In one aspect, a computer-implemented method for remotely resetting faulted wind turbines may generally include receiving fault data associated with a turbine fault that has occurred for a faulted wind turbine, analyzing one or more reset conditions associated with the turbine fault; determining whether the faulted wind turbine is remotely resettable based on the one or more reset conditions associated with the turbine fault and if the turbine fault is remotely resettable, transmitting a reset notification to a client device authorized to receive notifications for the wind turbine, wherein the reset notification indicates that the faulted wind turbine can be remotely reset.
