Advanced Features

• Multilin HardFiber IEC 61850 Process Bus Solution:  The Alstom/GE 889 Generator Protection System incorporates the Multilin HardFiber IEC 61850 process bus solution, which revolutionizes communication within the protection system. This solution utilizes fiber-optic cables to transmit digital signals, ensuring fast and reliable data transfer between devices. It enhances the overall efficiency and responsiveness of the protection system.

• Specific Protection Functionalities:

• Overcurrent Protection: The system offers comprehensive overcurrent protection, which safeguards the generator against excessive current flow. It continuously monitors current levels and triggers protective actions when thresholds are exceeded, preventing equipment damage and ensuring system stability.

• Differential Protection: Differential protection is employed to detect internal faults within the generator winding. By comparing current inputs at different points, the system can identify abnormalities indicative of faults. This feature enables swift detection and isolation of faults, minimizing downtime and maintenance costs.

• Synchronizing Protection: Synchronizing protection ensures accurate synchronization between the generator and the power grid during connection. It monitors voltage and frequency parameters to coordinate the generator’s output with the grid’s requirements, preventing issues such as voltage spikes or frequency deviations that could disrupt operations.
• Loss of Field Protection: Loss of field protection is crucial for preventing damage to the generator due to loss of excitation. This feature detects and responds to situations where the field excitation is insufficient, triggering actions to restore proper excitation levels or disconnect the generator from the grid to prevent damage.

• Real-time Monitoring and Diagnostics Capabilities: The Alstom/GE 889 Generator Protection System provides real-time monitoring and diagnostics capabilities, allowing operators to continuously assess the health and performance of the generator. This includes monitoring parameters such as temperature, vibration, and insulation condition, enabling early detection of potential issues and proactive maintenance planning.

• Integration with SCADA Systems: The system seamlessly integrates with Supervisory Control and Data Acquisition (SCADA) systems, facilitating centralized monitoring and control of the generator within the broader power network. This integration enables operators to remotely access and manage the generator protection system, ensuring efficient operation and rapid response to any events or alarms.
