Parallel Generator Sets: A complete guide to their operation and our solutions

Discover everything you need to know about the parallel operation of generators and the solutions we offer.

How do Parallel Generator Sets work?

Operating generators in parallel involves synchronizing two or more units at the same frequency and voltage, allowing them to work together to power a common network.

This configuration enables the generation of a large amount of energy, exceeding the capabilities of a single unit with similar characteristics.

This method ensures that there is always at least one main generator active and connected to the network, which can be rotated periodically to evenly distribute usage hours and plan maintenance in a staggered manner.

When the electrical demand exceeds a predefined threshold, another generator is instructed to start and connect automatically, distributing the load evenly among all active generators.

If the demand decreases, the additional generators are automatically disconnected and stopped, allowing maintenance to be carried out without interrupting the electrical supply, as the system disregards inactive equipment.

Benefits of Parallel Generators

  1. Energy Efficiency: Adaptability to demand fluctuations with lower fuel consumption, activating or deactivating units as needed.
  2. Continuity and Safety:  Ability to perform maintenance without affecting the electrical supply, ensuring constant energy even during repairs on the main unit.
  3. Enhanced Reliability: The simultaneous operation of multiple generators prevents failures and ensures an uninterrupted electrical supply.
  4. Maintenance Reduction: Less individual wear due to the distribution of operating hours among several units.
