Overview

The GDB021BE01 synchronizer module is part of ABB’s advanced control and protection portfolio, tailored for power generation and distribution systems. It provides automatic synchronization by continuously comparing the generator’s output with grid parameters and issuing a close command when conditions are met. This helps prevent equipment damage and ensures smooth power transfer.

Equipped with programmable logic, real-time monitoring, and synchronization protection, the GDB021BE01 is suitable for both manual and automatic control schemes. It supports integration into ABB Symphony Plus, Bailey Infi 90, and other DCS platforms, making it ideal for retrofit projects and new installations alike.

Technical Data

Typical Applications

The GDB021BE01 is widely used in power plants, substations, and industrial facilities with on-site generation. For example, it synchronizes backup generators with the utility grid during black-start or load transfer operations.

It is also deployed in renewable energy systems to manage synchronization between solar/wind inverters and the main grid. Its high synchronization accuracy and fast response time make it ideal for dynamic grid conditions. Engineers value its flexibility, diagnostic capabilities, and integration ease, especially in systems requiring redundant or multi-generator configurations.
