Grid feeding monitoring relay with modbus RTU guarantees grid stability

2017-12-08 - ABB’s intelligent CM-UFD.M*M range with Modbus RTU enables remote maintenance and failure analysis. T&D World article - December 7, 2017
ABB has launched a new grid feeding monitoring relay with a communication interface that enables users to visualize and store process data remotely, and to perform remote tripping, monitoring and maintenance analysis.

The ABB innovation helps overcome challenges that arise because power grids are not equipped for large-scale energy storage. To keep the power generated and the power consumed equal at all times, renewable energy sources must connect and disconnect to stabilize the grid.

The fluctuations that renewable energy sources bring to power grids make the challenge more complex. Changes in the weather can lead to sudden power increases in the grid that can increase the main feed’s frequency and the risk of a blackout

ABB’s intelligent CM-UFD.M*M  relay, with Modbus RTU, measures the grid frequency and manages the feed-in process, guaranteeing grid stability to prevent blackouts and protect electrical equipment.
