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
  - Power control
  - Discharge control
  - Water level control
  Integrated Control Functions
  - Surge control
  - Adaptive Cam Control (ACC module)
  - Flow Calculation (FCA module)
  - Surge tank Protection Module (SPM module)
  - and others

Due to the possibility of integrating unit protection as well as start/stop sequencing, TC 1703 can also be used as a complete compact control system.

Power Plant Management

Your Target

For single power plants as well as for power plant cascades, power production has to be maximised whereas the costs have to be reduced to a minimum.

Modern power plant management systems have to fulfil these tasks in a very efficient way. Beside the plant's operational requirements (e.g. maintenance cycle) the system has to take into account a number of external regulations (water management, contracts, environmental regulations).

Production planning requires different modules for forecasting and optimisation. Information has to be provided to other applications (e.g. commercial and administrative software tools) via standard interfaces.

All these different requirements require a modular overall concept.

Besides its main task - maximising of energy production - the system has to support the operators in all different operating conditions (e.g. normal operation, flood and disturbances). At the same time the system has to contribute to the reduction of operation and maintenance costs.

On the basis of the existing infrastructure, an easy integration into the power plant's environment must be possible.
