MEYGEN – ENGINEERING EXCELLENCE GRID ISSUES
It was Ronnie Quinn, General Manager of The Crown Estate’s Scotland Portfolio, who summed up the grid issue. He said: “We suffered from the illusion that if we build it the grid would come, but that hasn’t been the case: National Grid does not invest speculatively.” That grid remains such a key challenge is predictable for sectors whose resource is predominantly located far from our towns and cities.
But innovative solutions are starting to emerge, such as MeyGen’s joint use of a community windfarm’s grid connection, which Atlantis’ Tim hailed as a huge step forward.
SUPERVISORY CONTROL AND DATA ACQUISITION APPLICATION
MeyGen is the world’s largest tidal stream project, located in the Inner Sound of the Pentland Firth, between the north Scottish mainland and Stroma Island. Atlantis Resources Ltd is supplying their 1.5MW AR1500 tidal turbine to the project.
Atlantis Resources Ltd has over a decade of experience in tidal power technology, culminating in the AR series of turbines for high energy open ocean environments. The AR1500 has active pitch, full yaw capability and an 18-metre rotor diameter. Each 150 tonne turbine nacelle is approximately 11 metres in length and has a design life of 25 years.
DESIGN AND DEVELOPMENT
The product supplied by Atlantis Resources Ltd includes a PLC- based control system for the turbine and Cougar Automation Ltd designed and developed a Supervisory Control And Data Acquisition (SCADA) application to allow the remote monitoring and control of this turbine.
The key features of this web-based application, developed using Iconics Genesis64 are…
• Acquisition of live turbine data from the PLC using OPC UA protocol
• User-friendly graphical interface for data presentation and turbine control
• Full real-time and historical alarm management system • Collection, logging and display of turbine data using a high-speed, mission critical historian
• Distributed software architecture allowing scalability and process-related asset trees

It was no surprise that the conference, well-attended as it was by smaller developers, supply chain and professional services, was dominated by the huge success of MeyGen. The optimism that this clearly produced in through sectors so used to overcoming adversity was palpable.
And in the final session OpenHydro’s Sue Barr perfectly summed up the determination of the marine energy industry to succeed, saying: “Reverse engineer a challenge and you get an opportunity.”
