| Resumen: | A steam turbine generator is a very complex machine and very dangerous because it has the potential to explode. Therefore, it should be equipped with a control system and protection system. A protection system for steam turbine generators is more complex than other facilities in the power-generating industry. Due to its complexity, a high-skill operator is required to operate the facility. In this study, a simulator of a protection system for a steam turbine generator based on a distributed control system DCS ABB 800xA has been developed. The system was developed considering eight parameters to ensure safety, including turbine speed, inlet temperature, vibration, turbine shaft position, steam drum tank level, and lubricating oil pressure. The system also provides a manual emergency push button to anticipate an uncontrollable condition. The developed simulator has been tested to ensure it works properly and protects the steam turbine generator from abnormal conditions. Tests were performed to check interlocking responses caused by a single variable. All the variables have been tested. Another test was performed to check the ability of the simulator to detect abnormal conditions and respond to those conditions. All the tests showed that the simulator system could operate properly. The simulator system is very comprehensive in detecting the potential of turbine trips. This system considered all the variables that were highly reported as the factors of the turbine malfunction. It is the main advantage of the proposed system. The developed system provides significant benefits for training the operator without interrupting the operation of power-generating facilities. |
