Synchronization Solutions
Reliable power depends on generation sources working together as one coordinated system. PES designs and implements automatic synchronization systems for multi-generator and grid-parallel operations, built around industry-leading controllers such as the DEIF AGC-4 MKII and AGC-150. From single-genset AMF panels to complex multi-source installations running in parallel with the utility grid, our synchronization solutions ensure stable, reliable power across every operating mode — with the protection and control logic engineered to match your site’s exact load profile and operational requirements.
What we deliver
Multi-Genset Synchronization
Automatic synchronization of multiple generating sets into a single, coordinated power source. Our systems match voltage, frequency, and phase angle before closing, ensuring smooth, damage-free breaker operation and stable bus conditions every time.
Load Sharing & Load Management
Intelligent distribution of active and reactive load across running generators, keeping each unit within its optimal operating band. Automatic load-dependent start/stop brings capacity online only when demand requires it reducing fuel consumption, running hours, and maintenance costs.
Closed-Transition Changeover
Seamless transfer between power sources without interrupting supply to critical loads. By briefly paralleling sources before opening the outgoing breaker, closed-transition changeover eliminates the disruption of open-transition switching for sensitive processes and equipment.
ATS / AMF Logic
Automatic Transfer Switch and Automatic Mains Failure control that detects supply loss, starts standby generation, and transfers load without operator intervention then returns to mains and shuts down safely once stable utility supply is restored.
Protection Coordination
Engineered protection schemes using ANSI-coded functions, coordinated so that the correct device operates first and isolates only the affected section. Proper coordination protects assets, personnel, and supply continuity across the installation.
Grid Interfacing & Parallel Operation
Seamless interfacing with utility grids for import, export, and peak-shaving operation. We engineer the control, protection, and compliance requirements needed for safe, stable parallel running alongside the grid.
