Making remote wind monitoring a breeze
Issue: 
Monitor and measure wind flow at isolated mast sites for accurate energy yield and turbine placement calculations.
Solution: 

Install wireless 3G M2M routers at remote mast sites to transmit wind speed data over Spark New Zealand’s (formerly Telecom New Zealand’s) XT network in real time.

Benefits:

  • Remote real time observation and control
  • No fixed line requirements
  • Reliable access to Spark’s XT network
  • Simple setup
  • Withstands extreme environmental conditions

Wind power is one of the most important forms of renewable energy, and plays a key role in the shift from fossil fuels and nuclear power to clean energy. As a provider of engineering, management and specialist technical services to public and private sector clients in over 80 countries worldwide, Aurecon is a global leader in wind energy consulting.

Renewable energy targets and plans to cut carbon emissions are set by governments, but projects such as wind farm developments are largely financed by private investors requiring reliable energy yield predictions to make the right commercial decisions. Being a natural system, wind behaves irregularly over the short term and can present significant risk and accuracy concerns for financiers.

To overcome this challenge Aurecon provides accurate wind output assessments to help clients avoid costly miscalculations prior to the construction of wind farms, and to ensure that turbines are optimally positioned and dimensioned. In determining the technology best suited to the task of remotely collecting and monitoring wind flow speed and turbulence data, David Wahl, Renewables Engineer at Aurecon, selected NetComm Wireless’ 3G M2M Series (NTC-6200) router to measure wind data from isolated mast sites in New Zealand using Telecom’s XT network.

“Reliable access to Telecom’s XT network is extremely beneficial as our sites are located in remote areas where GSM coverage is often inadequate. The NTC-6908 router was easy to set up and its reliability has been cost-effective for our clients. The modems have been in operation for a couple of months and we have not had any problems during that time.”

“The NTC-6200 was the best product in the marketplace with the right design, specifications and frequency bands required for our application. The device was tested and found to work successfully, and has proven to be the ideal replacement for our existing iPort modems which operated on the Telecom CDMA network prior to being disabled in July 2012,” said David.

The need was for a router with the capacity to support live point-to-point and point-to-multi-point wireless data communications over vast distances without the need for fixed line infrastructure. The NTC-6200 routers were each connected to a Yagi antenna and a Campbell Scientific data logger and were then installed at eight remote mast sites to transmit wind data files from the field to the office using the Telecom XT network.

“Reliable access to Telecom’s XT network is extremely beneficial as our sites are located in remote areas where GSM coverage is often inadequate. The NTC-6200 router was easy to set up and its reliability has been cost-effective for our clients. The routers have been in operation for a couple of months and we have not had any problems during that time.”

The NTC-6200 supports remote monitoring over the air in real time and withstands harsh outdoor conditions. The meticulously tried and tested rugged enclosure utilises industrial strength components to operate effectively in temperatures ranging from -30˚C to 70˚C; and the wide input voltage range (8-28DC) makes the router suitable for diverse applications and environmental conditions.
