Wind Energy
Wind Assessment, Wind Prospecting, & Wind Turbine Performance
If you need to measure wind speed and wind direction to help determine whether your site is a
good candidate to harvest wind power, Campbell Scientific can help you. We offer high-speed
dataloggers for monitoring wind turbine power and performance. To complete your system, we also
offer a wide range of towers, sensors, and software that can be customized for your wind assessment
or wind turbine performance needs.
Our data acquisition systems monitor conditions at wind assessment sites, at producing wind farms,
and along transmission lines. Key components include dataloggers, sensors, and communications devices,
which are customized for each application.
Wind Monitoring System Benefits
- Systems perform long-term, unattended data collection.
- Nearly every available sensor can be measured.
- Dataloggers have on-board mathematical and statistical capabilities.
- Time-stamped data is recorded allowing historical analyses.
- Pagers, radios, phones, and other devices can report alarm conditions.
- Electrical devices can be controlled based on time or measured parameters.
- Rugged, low power design allows systems to operate in harsh environments.
Dataloggers used in Wind Monitoring
Our dataloggers can be used for many different purposes. They can
make and record measurements, control electrical devices, or both. The dataloggers multifaceted
capabilities include functioning as PLCs or RTUs. They have many different channel types, allowing
nearly all sensor types to be measured on a single unit. For example, one datalogger can measure strain
on turbine blades, wind speed, and power output of the turbine, even while controlling peripheral devices.
The CR1000 with an LLAC4 peripheral
can measure up to 10 low-level ac output anemometers. If long cable runs are being avoided, our
CR200-series dataloggers can be deployed in a wireless network
configuration, allowing cost effective monitoring at each level of a wind assessement tower.
The reliability of our datalogger systems ensures data collection, even under adverse conditions. Wide
operating temperature ranges and weather-proof enclosures allow our systems to operate reliably in harsh
environments. Because they have their own power supply (batteries, solar panels), our dataloggers continue
to measure and store data and perform control during power outages. Up to 2 million data points can be stored
in the datalogger's non-volatile memory, while Flash cards can be used to increase data storage to tens of
millions of points. Data is time- and date-stamped to provide key information for identifying and analyzing
past events.
Measurement Capabilities
Channel types include analog (single-ended and differential), pulse, switched excitation, and digital. Not
only are there multiple types of input channels, but each of these channels can be independently programmed
for various sensor types. Most sensors connect directly to the datalogger, eliminating the need for external
signal conditioning. Multiplexers and other peripherals can be used with most of our dataloggers to increase
the numbers and types of channels.
Control Capabilities
The ability of our dataloggers to perform advanced control functions is a great advantage. Powerful on-board
instruction sets allow unattended measurement and control decisions based on time or conditional events. Using
these instruction sets, dataloggers can be programmed to perform multiple control functions based on different
scenarios. For example, alarms can be triggered, phone numbers dialed, or equipment shut down if the system
detects an equipment failure—all without human intervention.
Wind Monitoring Sensors
Almost any sensor can be measured by our dataloggers, allowing the wind
energy system to be customized for each application. Typical sensors include, but are not limited to: sonic
anemometers, 3-cup and propellor anemometers, wind vanes, temperature sensors (air, water, equipment, and
product), solar radiation, electrical current, resistance, power, and voltage.
Communications
The availability of multiple telecommunications and on-site options for
retrieving data or reporting site conditions also allows our systems to be customized to meet exact needs.
Options include: radio, telephone, cellphone, voice-synthesized phone, satellite, and ethernet. Systems can
be programmed to send alarms or report site conditions by calling out to computers, phones, radios, and pagers.
Software
Our PC-based support software simplifies the entire data acquisition process,
from programming to data retrieval to data display and analysis. Our software automatically manages data retrieval
from networks or single stations. Robust error-checking ensures data integrity. We can even help you post your data
to the Internet.
