AMF 25 Comap controller set points

Summary

This video explains how to configure genset controllers for load-shedding operations, focusing on key parameters such as load-sharing, synchronization, and safety settings. It covers essential aspects like base load, voltage and frequency synchronization, system priorities for master and slave gensets, and protective measures such as overload and oil pressure safeguards. The speaker emphasizes the importance of matching the controller settings with genset specifications for optimal performance. The tutorial aims to help users understand and properly adjust the set points on their genset controllers for smooth and efficient operations during load-shedding.

Takeaways

• 😀 Load shedding set points for 400-800 kW gensets are crucial for system efficiency during power outages.
• 😀 The video focuses on understanding the controller settings for proper genset synchronization and operation.
• 😀 Key parameter for genset synchronization includes the load control PPM, which manages load sharing between gensets.
• 😀 The system base load is set at 700 kW, ensuring a consistent power level for the system.
• 😀 Nominal power, current city ratio, and voltage ratios are essential for syncing gensets correctly.
• 😀 Speed governing parameters, including limits for high voltage, are critical for proper synchronization before connecting gensets.
• 😀 Voltage and frequency checks are essential during syncing, with set windows ensuring they match before synchronization begins.
• 😀 The system uses a priority setting where the master controller holds a higher priority over the slave controller during load sharing.
• 😀 Idle time, crank attempts, and maximum cranking pressure settings are vital for the genset's start-up procedure.
• 😀 Temperature and oil pressure are monitored to prevent genset operation if values exceed set thresholds (e.g., 1.5 bars).

Q & A

What is the purpose of this video?

The video is intended to show the set points for the load shedding of gensets, specifically focusing on the process control settings and how to configure them for efficient operation.

What is the role of the 'load control ppm' setting?

The 'load control ppm' refers to the load sharing, and it helps in balancing the power output between multiple gensets during load shedding.

What does the 'system base load' of 700 kW refer to?

The 'system base load' of 700 kW refers to the minimum power required by the system to run efficiently and maintain stable operation.

Why is the 'nominal voltage' important in this context?

The nominal voltage is important because it defines the standard operating voltage of the system, ensuring that all gensets are synchronized properly before they start sharing loads.

What is the significance of the 'voltage PG ratio'?

The voltage PG ratio helps ensure that the voltage from the gensets matches and stays within a tolerable range for synchronization, preventing mismatches that could cause operational issues.

What does the term 'sync speed governing' mean?

Sync speed governing refers to the control mechanism that adjusts the speed of the gensets to ensure they are synchronized with each other before they begin sharing loads.

What is the 'phase window' used for?

The phase window is a defined range (measured in degrees) to check if the gensets are synchronized in terms of phase before they are connected to share the load. If the phase difference is too high, synchronization will not occur.

How does the 'voltage PF max' setting affect the gensets?

The 'voltage PF max' setting is related to the power factor of the gensets. It ensures that the gensets operate within the required voltage range for proper performance, typically for conditions involving voltage regulation.

What happens if the 'oil pressure' goes beyond the 1.5 bar limit?

If the oil pressure goes beyond 1.5 bars, the genset will not start. This is a safety feature designed to prevent damage due to abnormal oil pressure levels.

Why is it necessary to set up the correct master and slave controllers in the system?

Setting the correct master and slave controllers is necessary to establish which controller has priority in managing the load-sharing operation, ensuring that the master controller oversees the process while the slave controllers follow its lead.
