Removable Electronics Module for Wind Turbine Tower Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service and replacement of electronic components located in the lower portion of a wind turbine tower pose challenges due to structural weight and load considerations, requiring substantial support structures for access.
Innovation Solution
A wind turbine construction that includes a removable electronics module positioned within the tower, which can be lowered through the tower for service or replacement, utilizing a transition piece to create a space beneath the tower for module removal and support, allowing for easier access and accommodation of large components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If electronics are positioned within the lower portion of the wind turbine tower, then weight is removed from the upper end of the wind turbine, but service and replacement of electrical components becomes difficult and requires substantial support structures
Solution Approach 1:
The tower is divided into functional zones: the lower portion contains serviceable electronics housed in removable modules, while the upper portion maintains structural integrity. This segmentation allows electronics to be accessed from ground level through the lower tower section without compromising the load-bearing capacity of the upper tower structure.
Solution Approach 2:
A transition piece is introduced as an intermediary structure between the tower base and foundation. This transition piece creates a serviceable space that allows electronics to be accessed and replaced from ground level, mediating between the need for weight reduction and the need for ease of repair.
2Weight of moving object
If large electronic components such as transformers are positioned within the lower portion of the tower, then weight is reduced from the nacelle, but substantial support structures are required to accommodate openings for component passage
Solution Approach 1:
The transition piece is designed in advance with built-in support structures and opening configurations that are optimized for passing large electronic components. By preparing the support structure beforehand with appropriate openings and reinforcement, the need for complex on-site modifications is eliminated.
Solution Approach 2:
The transition piece serves multiple functions: it provides structural support for the tower, creates serviceable space for electronics, and facilitates the passage of large components during installation and maintenance. This multi-functionality reduces the need for separate specialized support structures.

AI summary
A wind turbine tower is supported on a transition piece that connects the tower to a foundation and that defines a space beneath the lower end of the tower. Electronic components positioned within a removable module in the lower portion of a wind turbine tower may be removed through a lower end of the tower for service or replacement.
