In facilities where a single generator is not enough or redundancy is critical, multiple generators must run in parallel. Synchronization panels prevent sources from closing onto the busbar before voltage, frequency, and phase angle are matched, and share the load evenly between the generators. Because faulty synchronization can cause serious mechanical and electrical damage to generators, these panels belong to the class of LV systems demanding the highest engineering discipline.
Miratek builds the synchronization solution on a controller-based architecture independent of generator brand; load sharing, staged run-up, and load shedding scenarios are parameterized to the operation's needs. Where grid-parallel operation is required, the protection functions are designed to the connection conditions. Commissioning is completed with on-load tests and scenario verification.

How We Work
Site survey and system analysis
The generator count, ratings, load profile, and operating scenarios are analyzed in place.
Design
The synchronization architecture, protection functions, and load-sharing scheme are approved on the design.
Panel manufacturing
The synchronization panel and controller infrastructure are manufactured in the workshop and function-tested.
Installation and integration
The panel is installed, generator control and power connections are made, and the controllers are networked.
Parameterization
Load sharing, run-up order, and operating scenarios are parameterized specifically for the facility.
On-load testing and commissioning
Synchronizing, load sharing, and fault scenarios are verified under real load.
Scope of Work

Frequently Asked Questions
Can generators of different brands and ratings run in parallel?
Generators with a suitable electronic regulator infrastructure can run in parallel across different brands and ratings using a controller-based architecture. Load sharing is parameterized to the generators' power ratios. At the survey stage, each generator's regulator and governor compatibility is assessed individually.
Why must the synchronization system be automatic?
Manual synchronization is open to operator error, and a faulty closure can damage the generator. An automatic system continuously monitors voltage, frequency, and phase angle and permits closure only when the conditions are met. That both protects the equipment and shortens the run-up time.
Is it possible to run the generators in parallel with the grid?
It is technically possible, but requires protection functions compliant with the distribution company's connection conditions. This scheme is typically used for uninterrupted soft transfer or peak load management. The design evaluates the connection requirements and provides the appropriate protection design.
