Flexible Turbine Control

State-of-the-art turbine controllers must meet the highest demands concerning safety, economy and availability. The basic requirements are a hardware platform suitable for industrial application and the use of international standards. Most modern, graphical user interfaces should allow for simple operation of the turbine controller. In addition, efficient remote parameterisation and diagnostic functions should be available for quick and simple maintenance and service access. Operational safety must be guaranteed even under the most difficult ambient conditions (e.g. moisture, EMC). Also the sensor technology for picking up the process signals must be designed to meet the highest requirements. Particularly the sensors for speed and servo motor position should be drift-free and thus be maintenance-free. The mechanical design should be optimised towards minimum space requirements.

The Common Solution

Since both the controller hardware and the standardised controller algorithm are modular, the application can individually be adjusted to the requirements of the power plant. After a functional test of the controller in the workshop, erection and commissioning is carried out by experienced specialist engineers. First priority is given to the safety of the plant at any time. Comprehensive services, spare part guarantees and training classes complete our scope of delivery.

Our Products

• TC 1703
  The modular TC 1703 offers all advantages of a modern, scalable turbine controller for the use as an individual unit, but also as an integrated part within the power plant automation system. Powerful 32-Bit microprocessor technology, integrated diagnostic functions and various configuration concepts assure highest availability. The modular system design allows centralised and decentralised interfacing to the peripheral signals. Efficient communication concepts allow for a simple integration into the existing plant. For quick hardware exchange, a modern plug-and-play concept is available.

• CAEx plus
  CAEx plus is a graphical engineering tool acc. to IEC 61131-3, which stands out for its simple operation and user-friendly programming.

• Reglerapplikation
  The turbine controller TC 1703 can be universally used for all turbines. lt can make use of standard PID schemes, advanced control algorithms with adaptable parameter setting values or state based control algorithms.
  
  Operation Modes
    - Speed control
