Monitoring and control of solar mirrors

The position of the sun changes during the day and throughout the year. Therefore, it is not possible to calculate the exact positioning in advance even for short periods.

The efficiency and productivity of a solar thermal plant is highly dependent on the amount of solar radiation. The output of power decreases dramatically if the temperature of the storage liquid is reduced, so it is important that the heliostats are constantly correctly positioned towards the sun.

In order to gain maximum effectiveness, the exact adjustment is fully automated. This can be achieved by equipping each heliostat with sensors, tracking systems and an industrial ethernet switch for communication.

Maximum uptime is a must, so there can be no single point of failure interrupting the communication during the maintenance, control and regulation of the solar plant. Maximum productivity can be achieved by planning the network structure (redundant ethernet ring topology) as well as choosing the right high-quality industrial graded products.

Highest availability and efficiency, in combination with reduction of installation time, can be guaranteed by choosing an easy-to-handle industrial network management system that provides operator access 24 hours every day.

Managed DIN Rail Mount Switches - RS20 family

Designed for industrial use, these switches deliver the following benefits:

  • Reduce installation time: DIN Rail mountable switch can be installed quickly
  • Maximum availability: fanless industrial design and dual power inputs deliver greater flexibility and complete reliability as the switch has a large operating temperature range of 0°C up to +60°C (or optional -40°C up to +70°C operating temperature plus conformal coating)
  • Maximum uptime: fully managed switches facilitate the use of redundant ethernet ring topology
  • Improve efficiency: system management via web, SNMP and CLI delivers stable operation and increases the security of the power generation park, as data transmissions of services are separated and structured through virtual local area networks (VLAN)

Solutions

Effectiveness and availability of a solar thermal plant is highly depending on the exact positioning of the solar mirror.

Be certain, by using BELDEN signal transmission solutions containing Hirschmann™ industrial switches in combination with industrial hardened BELDEN outdoor cables maximum up-time and productivity is guaranteed.

Armored outdoor fiber cables

Armored outdoor fiber cables deliver the following benefits:

  • Save space: more efficient use of conduit space thanks to small overall dimension of central tube design
  • Greater cost effectiveness: installation requires less material as well as a lower number of breakout kits
  • Faster installation: as the cable has smaller dimensions and weight

Oversized tube filled with optical gel delivers the following benefits:

  • Maximize availability and long lifetime (>30 years): the cable is highly resistant against stress
  • Outdoor functionality: suitable for outdoor use thanks to the cable’s consistency

Armoring with steel wires delivers the following benefits:
Greatest flexibility: most flexible armoring for outdoor cables

  • Stable operation: high Crush resistance results in low risk of signal loss due to external stress
  • Cost efficiency: the cable can be used as direct burial cable - no tubes needed
