Bachmann GSP274 Grid Measurement, Synchronization and Protection Module

The GSP274 module enables the safe, reliable and automatic synchronization

of generator units to the power supply grid. It also provides a number of

monitoring functions for generator and grid protection. The circuit-breakers

are tripped by the module directly via digital outputs and relays.

Additional digital inputs enable the monitoring of the relevant switching state.

The continuous monitoring of grid harmonics up to the 50th harmonic can

be used for direct reactions as well as for evaluating the power quality.

The module is provided with an integrated real-time data recorder for the

high-precision recording of up to 16 measuring channels during protective

tripping or synchronization. Error events are recorded continuously and

stored permanently with a high resolution time stamp. The internal time

base of the module can be synchronized to an external time source

(e.g. IEEE 1588 Precision Time Protocol), which supports the analysis

of the data from spatially separated measurement and protection devices.

The module is fully integrated in the Bachmann SolutionCenter.

Configurations can be created simply and stored for later reuse.

Both the measured channel values and also the derived values are made

available directly in the user interface. Commissioning and fault analysis

are simplified with tabular, vector and time sequence displays.

Event logs and recorded time sequences can be exported in CSV respectively

COMTRADE format. The integrated simulation function simplifies the

configuration of protection and monitoring functions.
