Energy | Solnova

Control system for energy-efficient production of

solar power.

One of the world’s biggest solar power stations is the Solnova plant near Sevilla in Spain. The plant is based on concentrated solar power (CSP) designed by Danish Aalborg CSP and Init has delivered the solar power control system.

 

Our favourite type of project is one where we can apply our process knowledge and automation skills combined with IT competences to develop solutions that support sustainable development. This project for Solnova is a great example of one such project.

Aspiration: Effective control of energy power plant

 

When it was built in 2009, the Solnova Solar Power Station was among the world’s largest concentrated solar power (CSP) plants.

 

The plant will replace traditional energy sources with green energy. More concretely, the plant aims to:

  • Generate 250 MW of power (from five units each generating 50 MW).
  • Supply electricity to more than 30,000 households in Spain (approx. 90,000 people)
  • Reduce CO2 emissions by 31,400 tons per year

 

To obtain optimal power from the sun, effective control of the entire plant is essential.

Solution: Joint effort ensures robust solar power control system

Init delivered the control system and electrical panels for the power plant’s heat exchanger and boiler delivered by Aalborg CSP.

 

Solnova had a clear vision for the plant and Init made a control philosophy to fulfil the vision. To do that, Init’s engineers joined forces with Aalborg CSP’s technology experts and the customer team. Together, we analysed and defined what was needed to achieve the goal, taking electrical, mechanical and environmental concerns into consideration.

 

We then installed a redundant control system based on Rockwell/Allen Bradley PLC system with local HMI to fulfil the identified requirements. The system ensures close to 100% up time and safe operation, even in case of failure in one system. We implemented all functionality needed to operate the plants in interfaces for the common control room at site.

 

Subsequently, we built, tested and adjusted the solution together on-site to ensure optimal production.

 

 

Result: Paving the way for Spain’s green transition

 

All five plants operate in conjunction with other solar power solutions. And staff can operate all processes from local control rooms where operators supervise and control all five plants.

 

These plants play an important role in Spain’s transition towards renewable energy.

Facts about the plant

The plant consists of five units with 50 kilometres of parabolic troughs each.  The troughs adjust according to the sun using solar energy to heat a pipe with circulating oil. The oil is used to feed a boiler which is heated to 500-600 degrees. The steam generated from the boiler and overheater is then directed to a turbine which produces electricity via a generator.
