LiDAR Energy Station

LiDAR Energy Station

L.E.S. IS BEST

With the increased growth of the wind energy industry we have seen some new emerging technologies most noticeably the application of LiDAR technology.  

A LiDAR is a laser based wind profiler device for wind speed measurement and directional data capture. A LiDAR is a remote sensing technology that is now successfully being used for wind mapping applications. 

A LiDAR requires a reliable electrical supply. This has become a major challenge when a LiDAR is deployed in “off-grid” environments. Due to the increase in demand for LiDAR power solutions Hybrid Energy Solutions has designed an innovative solution for this market in the form of the LiDAR Energy Station.

The LiDAR Energy Station is a high security enclosure consisting of 3 compartments; LiDAR, Battery and DC generator. The LiDAR Energy Stations primary power is provided from a 48V battery bank and the generator recharges the battery intermittently. The Energy Station can provide a power of 12VDC, 24VDC, 48VDC and/or 230V AC depending on the client’s requirements.

The Energy Stations are fully equipped with remote monitoring and control capabilities which send SMS and email alerts in the event of a pending fault condition. In addition the unit has full monitoring of the fuel usage and fuel available, and will send alerts if the fuel reserves are low. All historical data is recorded and available via a web portal. 

LiDAR Energy Station vs AC Generator 

The LiDAR’s low power consumption can cause mechanical issues when run by a standard AC generators such as build-up of carbon deposits in the engine and moisture ingress to the alternator, both causing catastrophic failure.

HYbrid’s inventive solution allows the engine to run at its most fuel efficient state with the excess power used to charge to battery bank. The average fuel consumption from the LiDAR Energy Stations currently in the field is approx. 15 litres per week. This compares very favourably to a typical AC generator which uses around 250 litres per week. The Energy Station has a 600 litre internal bunded fuel tank which on average will need to be refuelled once every 9 months and minimizes the risk of fuel spillages. 

Carbon footprint is reduced by 95% over a conventional AC generator power source.

The LiDAR Energy Station also reduces maintenance requirements, allowing extended operation of the equipment without manual intervention. Service visits are reduced to one per nine months, with remote monitoring giving constant feedback and assurance that everything is operating as it should.

LiDAR Energy Station vs Solar Options

The LiDAR Energy Station offers 100% reliability with up to 5 days back up time in case of faults. Solar panels are of course useless during night, poor weather condition or wooded areas which can leave the LiDAR vulnerable to power outages which can cause a loss in data. Therefore these must be backed up with extremely large and expensive battery banks to store power when available.

The location of solar panels is of major influence in solar power generation. Areas which remains mostly cloudy and foggy will produce electricity but at a reduced rate and may require more panels to generate the required power. The Energy Station offers flexibility of location. Solar energy systems require a large surface area of solar panels to provide a reliable source of electricity. Compare this to the LiDAR Energy Station which has a footprint of 1956mm x 1500mm (w x d). 

Security is a major issue with solar panels located in rural areas while the LiDAR energy station provides high security for all components, including the LiDAR. The high value of the LiDAR equipment means considerable lengths must normally be taken to secure the unit, resulting in considerable additional expense. The LiDAR Energy Station enclosure helps prevent theft and vandalism of this equipment due to its thick steel construction and strong locking mechanism.
