Solution Overview

Problem

Wind turbines located far from operators face challenges in remote monitoring and maintenance, leading to reduced efficiency and unrecoverable revenue losses due to the inability to perform remote restoration of normal operation without altering existing control logic or hardware.

Innovation Solution

The implementation of a local intervention controller (LIC) system that allows for remote restoration of wind turbine operation using existing communication infrastructure, enabling remote monitoring and control without modifying the turbine's control logic or hardware, and utilizing existing communication paths to interface with the turbine's control systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If wind turbines are installed far from human operators to maximize power generation capacity, then power generation capacity is improved, but the ability to perform maintenance and restoration is worsened

Engineering Contradiction:
Improvepower generation capacityVSAvoidability to perform maintenance and restoration
Core Design Contradiction:
PowerVSEase of operation

Solution Approach 1:

The patent introduces a remote interface system that acts as an intermediary between operators and distant wind turbines. This system includes a remote computer with user interface that communicates with turbine control systems through existing communication infrastructure, enabling operators to monitor and control turbines from remote locations without being physically present at the turbine site.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of repair

If technicians are required to be physically present at remote turbines for maintenance, then restoration capability is improved, but response time and availability are worsened

Engineering Contradiction:
Improverestoration capabilityVSAvoidresponse time and availability
Core Design Contradiction:
Ease of repairVSLoss of time

Solution Approach 1:

The patent enables self-service remote maintenance capabilities where operators can diagnose and restore turbine operation without physical technician presence. The system allows remote execution of diagnostic routines, review of alarm conditions, and initiation of restoration procedures through the remote interface, reducing dependency on physical technician deployment and minimizing downtime.

Inventive Principle:
Principle #25Self-service

3Productivity

If remote intervention capabilities are added to existing turbines, then operational efficiency is improved, but system complexity is worsened

Engineering Contradiction:
Improveoperational efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent designs the remote interface system to leverage existing communication infrastructure and control protocols used by wind farms. The remote computer can interface with multiple turbines using standard communication paths, and the system supports various operational functions including monitoring, diagnostics, and restoration through a unified interface, reducing the need for turbine-specific customizations and minimizing added complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An embodiment provides controllers modules that allow for an energy generation module, such as a wind turbine, to be restarted locally and remotely. To restart the energy generation module remotely, care is taken to ensure the module is not in lock down mode. Further, the adding the ability to remotely restart the module does not alter the code or logic used to locally restart the module. Other embodiments are described herein.
