Grid Measurement Modules | Safety and efficiency of the electrical energy supply
Source: Bachmann System Overview catalog | Bachmann electronic GmbH www.bachmann.info.
The safety and efficiency of the electrical energy supply are placing increasing demands on the generator units, transmission systems and consumers. A new generation of systems for measuring, monitoring and protection provides an essential technical basis. Our grid modules supply the latest state-of-the-art technology as a fully integrated solution in the automation units of the M200 system. This provides modular expansion capability, data storage and communication over several fieldbus and telecontrol interfaces that are simple and affordable.
High resolution and fast acquisition of all grid variables forms the indispensable basis of all grid modules. The integrated energy metering simplifies handling in engineering and operation. In order to ensure network stability, generator units must be able to guarantee a defined response according to the relevant grid codes. Faults in the grid or in the plant must lead to defined responses such as the provision of control power or grid disconnection.
The GSP274 and GMP232 module series offer for this configurable protection and monitoring functions in accordance with the latest standards. The integrated harmonics analysis function deals with the problems of power quality caused by increasingly larger power electronic components. Precise, time-stamped event logging and integrated real-time data recorders provide a convenient basis for commissioning or fault analysis. Furthermore, the GSP274 modules also provide a synchronization unit for the automatic grid coupling of generators. GM260 modules impress with their particularly compact design and simple handling for consumption optimization and energy monitoring.

Grid Measurement, Protection and Synchronisation Module GSP274
The GSP274 enables the safe, reliable and automatic synchronisation 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 responses as well as for evaluating the power quality.
The module is provided with an integrated realtime data recorder for the high-precision recording of up to 16 measuring channels during protective tripping or synchronisation. Error events are recorded continuously and stored permanently with a high resolution time entry. The internal time base of the module can be synchronised 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 GSP274 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, phasor 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.

Grid Measurement Module GM260
The GM260 module enables the safe, reliable and fast measuring of all relevant values for three-phase electrical networks. Two separate three-phase branches can be measured if there is a common voltage measuring point. The grid variables are calculated online in the module as True RMS values including harmonics up to the 40th harmonic. This is particularly useful for applications such as for operational measurement on machines or the energy monitoring in plants and buildings. As well as functions for determining the active, apparent and reactive power for each phase, two separate 4-quadrant energy counters are directly integrated in the module. The GM260 module is fully integrated in the Bachmann SolutionCenter. Both the measured channel values and also the derived values are made available directly in the user interface.
- Measurement of current, voltage, frequency, power, power factor, phase angle
- Direct connection to input voltages up to 480 VL-L, RMS
- True RMS calculation online
- 2 independent 4Q energy counters
- Compact design for 2 three-phase branches
