PATSAIndustry Solutionsin Turbine Control Systems
These the days, the functional safety of turbines and compressors is becoming a focal point of industry. A small accident can have catastrophic consequences, endanger human lives, and incur high costs. The International Electrotechnical Commission reacted by introducing stricter safety standards. Patsa Industry is in a position to meet these standards with consolidated system solutions for safety and critical control.

The constant changes in turbo machine industry has raised questions and concerns with stakeholders. For some time now working groups have been dealing with the question as to whether turbo machines have to meet the requirements and guidelines of the machinery sector or the process industry. The principles of functional safety, as normally applied in the process industry, will also be defined in the near future for turbo machines. These requirements are by no means just a burden; they are an opportunity to achieve higher plant productivity
Gas Turbine Applications
Today’s biggest challenge is to match plant production to electricity generation demand with flexible rapid responses. Patsa Industry solutions for Gas Turbine Control System supports all the complex technologies to offer highest operational flexibility for the entire power plant, while boosting power and efficiency. It provides advanced control algorithms that are used to implement standard closed and open loop controls such as:
- Optimized automatic startup with model based controls as compared to the traditional operating curves
- Speed and load control
- Integrated vibration monitoring
- Integrated turbine protection
- Advanced operability and performance
Patsa Industry Gas Turbine Control System is based on the latest available technologies from brands such as HIMA to provide a consistent solution for light or heavy duty gas turbines.

Steam Turbine Applications
Patsa Industry Steam Turbine Control Systems solutions portfolio covers a wide range of steam turbines from the industrial units, including turbo-compressors and turbo-pumps. Thanks to our experience in this field, Patsa Industry has developed a range of solutions adapted to each set of unique requirements. Based on a standard redundant configuration, our scalable solution provides speed and load control with various limitations and includes all the steam turbine protection required. For maximum availability, our control solution is also available in a full Triplicated Modular Redundancy, including a full TMR SIL3 protection system with a normal overspeed protection and a backup overspeed protection.
Control System Features
- Standardized configurationPatsa Industry provides all the functions for the industry that include automatic speed control, load control, and limitation, with a user friendly graphic interface to ease the operation and the maintenance of the unit. Based on a standard hardware and software configuration, additional features such as an electronic SIL and overspeed protection may be provided with integrated test.
- Fully integrated solutionPatsa Industry Turbine Control System uses a hardware and software platform configuration for both safety and control. This fully integrated solution provides single plant control for your most valuable asset. In addition, maintenance, diagnostics, spare parts, logistics, alarms, databases, and training are required for just one system— simplifying operations.
- AvailabilityAvoiding unplanned outages is key. In addition to the highest availability features of Triple Modular Redundancy (TMR) architecture capability for asset control and protection, our Turbine Control Systems provide features for prevention and troubleshooting. Fast data recording with time stamping and an advanced monitoring solution for real time analysis of data greatly simplify root cause analysis.
- SafetyWithout safety and security there is no sustainability. Safe operation is reinforced through IEC 61508 SIL3 certified modules, fail-safe designs and TMR protection systems. Our Turbine Control System solution with SIL-capable protection is designed for peace of mind, meeting the functional safety requirements of IEC 61508 and 61511.

HIMA TMC (Turbo Machinery Control)
FlexSILon TMC ensures all turbomachinery runs safely. FlexSILon TMC from
Fig. 4 FlexSILon TMC Overview
HIMA TMC is designed with safety and functionality in mind (fig. 4):
- Based on proven HIMax® safety system
- Integrated overspeed trip (OST)
- Optimal investment security, possible to convert from non-safety-related automation loops to safety-related
- Nonstop operation over the entire lifecycle of your equipment
The decision to opt for FlexSILon TMC from HIMA is not only one of installing a safety system; it is the decision to implement process optimisation with greater investment security. Monitor, regulate, and control your turbomachinery centrally. This eliminates the need for numerous single-purpose solutions from different manufacturers. FlexSILon TMC combines two proven HIMA products: The flexible HIMax platform ensures uninterrupted operation of your plants. SILworX enables you to configure and program turbines and compressors and diagnose problems.
