Solutions for energy supply and power quality

SIMETAL / SIROLL Power provides top-class solutions for every power requirement. With a worldwide network of experienced experts, we offer the development, manufacture, and installation of systems for substations and distribution systems in metallurgical plants – tailored to your technological process needs and utility requirements.

In the metals industries nothing functions without an adequate power supply. That is why the planning phase of the power distribution for such processes needs to be guided first and foremost by process knowledge! This, combined with know-how on energy distribution and utility needs is the basic prerequisite for success – after all, the safety, reliability, and cost-effectiveness of the plant largely depend on its power supply.

Benefit from our extensive know-how in the fields of high, medium, and low-voltage stations (all the way to complete turnkey solutions) combined with our knowledge about the specific needs of your technological process. We create a solid basis for smooth production processes. By providing safe energy supply throughout the plant, we insure greater operational safety, the same hard- and software base for lower-cost energy and process automation, and solid emergency power strategy to reduce the risk for your plant.

Power Distribution

Allowing your production to run smoothly and reliably – without downtimes caused by power failures or fluctuations

Secure power supply via a well designed and well equipped supply network is one of the prerequisites for successful plant operation. High-performance transformers, for example, are as important as the right switchgear solution for the various requirements. Siemens VAI solutions are designed to meet the requirements of the metals industries and their high demands with respect to operator safety and operational reliability.

Power Distribution: Emergency Power Control

Ensuring safety under all circumstances

Power failures or power outages in the metals industries can cause severe consequential damage to the plant and even endanger human life. To prevent such occurrences, an emergency power supply with black-start is recommended. Based on our long-term experience and in-depth knowledge of the process, Siemens VAI can determine the loads that should be connected to the emergency power supply to prevent damage or malfunction.

Power Distribution: Supervisory Control and Data Acquisition System (SCADA)

Visualize your processes and optimize your energy flow

Our SCADA system is based on a high-performance SIMATIC S7 system with fast cycle times and integrated control functionality – such as load shedding, error reporting, and logging. The WinCC control and monitoring interface is integrated within the IT plant concept and provides a consistent look and feel. Interfaces to higher-level IT systems enable intelligent energy management with requirement analysis and forecasting.

Power Distribution: UPS Systems

Static uninterruptible power supply (UPS) systems for automation systems and servers

Siemens VAI can assist you in the implementation of an effective protection system. Based on our long-term experience and in-depth knowledge of the process, we are able to determine the loads that should be connected to the UPS system to prevent damage or malfunction. A sufficient bridging period of the battery should be provided to allow for a controlled shutdown of all automation systems following a mains break.

Power Quality (SVC) & Filters

SIMETAL PQ – Reducing system perturbations in steelworks for a clean and stable voltage

SIMETAL PQ is an end-to-end solution focused on all aspects of your plant and the overall power supply system. Our key function is to correctly assess and manage the system perturbations in your plant's power network configuration.

Depending upon the unique configuration of your plant, its supply system, and the utility company's power quality requirements, we provide custom-made compensation system solutions such as filter circuits or thyristor based SVCs. (Static Var Compensation)

Power Quality (SVC PLUS®)

SIMETAL PQ - This system is installed when a conventional SVC does not offer sufficient flicker reduction.

The dynamic element of SVC PLUS is a voltage source converter (VSC) comprised of series-connected IGBT modules, each with a capacitor in the DC link. The VSC is capable of providing reactive or active power with a high slew rate/fast response time, which can achieve a significantly higher flicker reduction compared to a conventional SVC.

Furnace Switchgears up to 4000 A

SIMETAL SIVAC-X - High currents, high voltage – high safety

We assure carefully planned installation and protective circuits that are custom-designed for your electric arc furnace power supply system. In this context, we not only offer more than 30 years of experience in vacuum circuit breakers, but also our deep knowledge of their specific use as furnace breakers. With SIMETAL SIVAC-X you can avoid dielectric overloading of your equipment, even in the presence of voltages of up to 40.5 kV and current levels of up to 4000 A.
