The TURLOOP control system, with global sales of more than 400 systems to date, provides Siemens Energy Service with a successful automation system for industrial steam turbine applications. To supplement this, TURLOOP CS was developed as a compact, budget variant.
The system platform is based on proven Simatic S7 standard components, allowing flexible use for industrial steam turbines including extraction turbines with up to two extractions and irrespective of whether these are used as generator, compressor or pump drives. Further high performance features of TURLOOP CS include provision for up to five configurable process controls and a maximum of eight final control elements with position controllers. The new control system also implements limit controllers for generator load, inlet pressure and backpressure, as well for extraction and wheel chamber pressure. Linearization curves can be parameterized for all final control elements. The system also permits automatic startup of the turbine and runup to nominal speed, while distinguishing between cold, warm and hot starts.
The system features on-board two-channel speed measurement for eddy-current sensors. TURLOOP SMM-DP speed measurement allows connection of all standard eddy-current sensors and proximitors, as well as interfacing with electronic overspeed protection systems via an adapter module. Where eddy current sensors are used, continuous monitoring of gap between speed sensor and pulse wheel is possible. Speed actual values are transmitted to the central computing unit fast and error-free along a PROFIBUS link.
Parameterization menus are used to adapt the system to the turbine via a 12-inch touchscreen, this also permitting comfortable system operation during turbine operation. Customer designations and tags from standard identification systems can be stored and displayed in the system. No additional software or hardware is required here for parameterization.
Use of standardized and tested hardware and software ensures operating safety and reliability. Parameterization errors are detected, thus preventing "impossible" configurations. Self-diagnostic features are integrated in the control system. Provision is also made for backup of configuration data to a USB drive.
Power plant service is part of Siemens’ Environmental Portfolio. In fiscal 2009, revenue from the Portfolio totaled about EUR23 billion, making Siemens the world’s largest supplier of ecofriendly technologies. In the same period, our products and solutions enabled customers to reduce their CO2 emissions by 210 million tons.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
