For the existing steam turbine, software was created in PCS7 in order to integrate the steam turbine into the existing process control system. As part of the automation, the entire EMSR technology was renewed.
In order to ensure continuous stable operation and to enable rapid response, sophisticated turbine control has been implemented. Particular emphasis was placed on ease of use and easy understanding by operators, and the user interface was implemented accordingly using the Siemens APL library. The scope ranges from automated start-up with turbine warm-up to excitation, synchronization, the interface to generator protection, and speed and extraction control – enabling an immediate response to load changes and uninterrupted supply to the entire plant in the event of a grid failure.
The turbine can be used both in grid mode and in island mode.
Functional safety was also part of the project: enet carried out the documentation and initial verification of the specified Safety Integrated Functions in accordance with EN 61508 / EN 61511.
