Load Sharing Design

Purpose

• Objective: To evenly distribute the electrical load among multiple generators to optimize performance and prevent overloads.

Types of Load Sharing

• Droop Load Sharing:

  • Principle: Generators are set with a droop characteristic, where output voltage slightly decreases with increasing load, allowing proportional load sharing.
  • Implementation: Adjust governor settings to achieve desired load sharing.

• Isochronous Load Sharing:

  • Principle: Generators maintain a constant frequency regardless of load changes, using advanced control systems for precise load distribution.
  • Implementation: Utilize digital controllers and load sharing devices for accurate load balancing.

Load Sharing Techniques

• Manual Load Sharing:

  • Load Adjustment: Manually adjusting generator outputs to balance load distribution.
  • Monitoring: Continuously monitoring load levels and generator performance.

• Automatic Load Sharing:

  • Load Sharing Controllers: Devices that automatically adjust generator outputs based on real-time load demands.
  • Communication Systems: Integration of communication systems for synchronized operation of multiple generators.

Design Considerations

• Load Sharing Equipment: Include load sharing controllers, communication interfaces, and monitoring systems.
• Efficiency: Design systems to maximize generator efficiency and minimize fuel consumption.
• Reliability: Ensure redundancy and failover mechanisms to maintain load sharing during equipment failures.
