Optimize efficiency and safety in solar thermal plants with machine vision. Calibrate heliostats, monitor receivers, and detect fluid leaks to ensure continuous operation and reduce costs in tower and parabolic trough plants.
Parabolic trough solar thermal plants are currently the most mature technology and with the greatest presence within the solar thermal sector. In this equipment, both the temperature of the collector tube and the heat transfer fluid are important parameters when determining the state of the plant, as well as being critical control points. Added to this are other parameters such as the level of buckling of the tubes, dirt on the mirrors, state of the tube coating, among others.
To cover the need in these plants for a fast and efficient system for preventive / predictive maintenance, the continuous thermographic monitoring system that, integrated with FLIR cameras and high-performance drones (MTOW > > 5 kg) , it is possible to carry out complete inspections in this type of plants to monitor different parameters such as:
The reason of why the measurement of solar attenuation in a solar power plant relies on solar extinction being the main cause of energy loss.
The system consists of positioning the cameras one behind the other at a large distance and both taking images of the target. The system will measure the intensity levels of the digital images, which will provide with the diffuse radiance coming from the target. The intensity difference or light attenuation between both images, provides the attenuation, being βExt the attenuation coefficient considering both, the absorption and scattering mechanisms, and dependent on humidity, aerosols and particle concentration in the atmosphere.
bcb has developed an advanced software solution that, in combination with state-of-the-art hemispherical cameras, allows for highly accurate visualisation of the sky above the plant and provides the operator with valuable information on the amount of clouds and their behaviour (position and movement) in the environment where the solar thermal plant is installed.
This system offers a real-time image and detailed projections, helping operators to anticipate weather changes and optimise the performance of solar concentrating systems, both tower and parabolic trough collectors.
While this technology is specifically designed to maximise the efficiency of solar thermal plants, it also finds applications in key sectors such as meteorology, aviation and agriculture.
