Bachmann electronic GmbH is rolling out its new GMP232 grid measurement and monitoring module for wind power plants.
Integrated with a programmable logic controller (PLC), the module is suited for electrical, three-phase networks. This latest generation of the GMP232 offers additional calculation processes, high-precision frequency measuring and enhanced protection functions, the company says.
Moreover, the solution combines plant control (operational control) and grid technology in a modular unit.
Bachmann says the GMP232 modules, which have been designed to meet the requirements of decentralized gensets, can be used at the grid-connection point of renewable energy projects.
The company adds that the modules have wide measuring ranges and a high degree of accuracy. The frequency measuring is based on algorithms that considerably improve resilience to grid faults and, at the same time, ensure a frequency accuracy of 1 mHz.
Grid and system protection can be implemented via the configurable monitoring functions, and the data can be routed to the operational control programs of the controller. Relay outputs enable the direct switching of two tripping circuits independently of the remaining PLC system, Bachmann notes.
The GMP232, which can be used as a PLC-integrated solution, can also be used in combination with a small M1-CPU as an autonomous grid-measuring product.
