System selected to control new solar thermal plant in UAE

The Shams-1 solar
thermal power plant
Madrid, Spain — ESI-AFRICA.COM — 02 June 2011 – Telvent “’ a Spanish global IT solutions and information services provider that improves the efficiency and safety of the world’s leading companies “’ has been selected to design, install and manage the distributed control system for Shams Power Company’s Shams-1 solar thermal power plant in Madinat Zayed, 120km  southwest of Abu Dhabi in the United Arab Emirates.

This joint venture with Masdar (60% holding) Total (20%) and Anengoa (20%) selected Telvent’s system to control and operate one of the world’s largest concentrated solar power projects, and the first of its kind in the Middle East.

Extending over an area of a massive 2.5sq km, the plant will generate 100MW of power from 768 parabolic trough collectors. A parabolic trough is a solar energy collector constructed as a long parabolic mirror, usually coated in silver or polished aluminium.

Sunlight is reflected by the mirror and concentrated on a Dewar tube, which is designed with one tube contained inside another, and a vacuum space between them. This reduces heat transfer by conduction. For solar applications both tubes are usually made of glass and coated in silver to reduce heat loss caused by radiation. The trough is usually aligned on a north-south axis and rotated to track the sun as it moves across the sky each day.

With this Telvent solution, Shams Power Company’s plant operators will have the ability to control and supervise all solar plant processes in accordance with the most current technology, enabling them to manage the position of the solar trough collectors to efficiently capture the sun’s energy over the entire course of the day, anticipating weather conditions and improving the power block output.

According to Telvent chairman and CEO Ignacio Gonzalez, this Telvent/Shams Power Company initiative is one of the largest solar projects on the planet.

The company is a leader in developing and implementing solutions for the delivery of intelligent information to maximise solar energy production. This project marks the 12th Abengoa-owned commercial power plant for which Telvent has developed integrated control systems. It also has installations with integrated solar plants in Spain, the United States, Algeria and Morocco.
