Abstract

Enhancing service and communications inside offshore wind turbines by seamless HSPA

Introduction

Offshore wind farms are now being installed mostly far away from shore and enhanced planning activities are needed for a O&M operation to be correctly performed. Supporting and providing emergency help to technicians on a wind turbine may be difficult due to the lack of technologic solutions that provide a transparent service.

Keywords — SCADA, GSM, 3G, Data package, Circuit switch data

Approach

The paper explains how an offshore wind turbine should be fitted to enhance remote control and fit service teams with permanent voice and data connections, using a regular cell phone or data card. The technology and system allows to be remotely managed to have full control over the installed system.

Main body of abstract

This solution was though for Offshore but it’s model is also applicable to onshore wind farms. The difference is that offshore wind farms are usually much more exposed to the lack of voice and data links that are not interconnected with the wind turbine itself. This paper will describe in detail how to rollout a new infrastructure and control system to allow independent voice and data in each new wind turbine (considered a new 3G cell). The technologic approach is given by the capability to use the current wind turbine communication structure and implement a new layer that allows transparent access for technicians and engineers.
This systems should work together with the implementation of a mesh solution capable of ensuring multipoint redundancy and the conversion of all circuit and packet data to IP.
The paper also explains how these solutions are meant to reduce the risk and operation times, as well as allow centralized support for externals.


Conclusion

With the implementation of this kind of systems, with an irrelevant price compared to the existing satellite connections, the entities operating the offshore farms will be able to deploy advanced connectivity with secure, reliable, fast and transparent equipment without having to modify the existing telecommunications structure and using the existing gsm and 3G cards.


Learning objectives
Explain the technology solutions that should be available for offshore wind turbines, that allow service teams to be contacted without restrictions, configuration free and improve cost reduction models.
