Did you know that the UK is the windiest country in Europe?
*Insert your own joke here*
Wind has been the fastest growing
renewable energy source in the last decade. China plans a 60% increase in the next three years, and the US a massive six-fold jump by 2030! The EU wants to produce
20% of its energy through renewables by 2020, with the majority coming from wind. One wind turbine can generate up to 6.5 million units of electricity each year: enough to run a computer for 2,250 years. Thats quite a long time.
It's really very simple -
- Wind turbines convert kinetic energy from the wind into mechanical energy.
- The blades catch the wind and turn the rotor, which is connected to the nacelle which houses all the workings for the turbine.
- The rotor turns a shaft which is connected to the gear box.
- The gear box is connected to a generator which converts the mechanical energy into electricity.
- The electricity is then sent to the National Grid.
With all this going on, it's really important to ensure these turbines operate safely, so
strict monitoring is necessary. This usually involves a variety of sensors, including accelerometers, encoders, temperature sensors, oil/liquid level sensors, particle counter, voltage, current and humidity sensors.
UEI Cubes, and in particular, the
UEIPAC, are ideal solutions for
monitoring and controlling wind power generators. They are powerful enough to provide control for everything from blade angle to output voltage, and log everything from wind speed to power output. The UEIPAC’s easy access to Ethernet means it can easily run as a slave to a primary host PC when desired, but can take over and run stand-alone if anything happens to the primary communications link. The
Cube’s rugged environmental specification eliminates the need for any heating or cooling in the control rack.
The standard
UEIPAC cubes are tested from -40° to +85° C, at 50 g shock, 5 g vibration and altitudes up to 70,000 feet. All the I/O is also fully isolated from the controller, so the UEIPAC is almost totally immune to the glitches and spikes commonly seen in the grounds of an industrial environment.
We've also been speaking to customers who use UEI’s Cubes and RACKtangles as remote communications links in wind farms, where the system needs to consolidate
RS-485 data from a series of turbines and send the data to the supervisory computer.

Have a great weekend!
Syrinix Ltd, based in Norwich, has developed the Trunkminder, a fully automated data acquisition system designed to continuously monitor water pipelines, in order to detect leaks before they become a major problem. Trunkminder uses an array of sensors attached to pipelines to provide instant alerts if a leak occurs, and to gather data which provides real-time information on what is happening in the pipe. Working at a significantly higher level of sensitivity than traditional pressure/flow-based devices, alerts can identify the site of a leak to within one metre.
Based in Norwich,
Syrinix Ltd delivers high tech, continuous, intelligent and fully automated
monitoring and detection services for the water industry. Syrinix’s TrunkMinder service utilises a combination of
sensors permanently attached to pipelines, including a hydrophone, geophone,
pressure sensor and optional flow monitor.
