Alstom/ GE MiCOM Agile P341 Interconnection Protection and Dynamic Line Rating

The GE MiCOM Agile P341 interconnection protection and dynamic line rating relays offer the protection requirements necessary for operating machines in parallel with the main power supply network. The P341 generator protection relay can be customized to meet the specific needs of the intended application. It offers complete, cost-effective and highly reliable protection for interconnecting distributed generators to the grid. The P341 also includes Dynamic Line Rating (DLR) protection to optimize transmission line capacity.

GE’s MiCOM Agile P341 generator protection relay provides flexible and reliable integration of protection, control, monitoring and measurement functions for a wide range of applications. The P34x relay platform is available in six models that cover most installations from small generators to sophisticated systems including generator-transformer applications and large variable speed double fed induction pumped storage machines.

GE’s generator protection devices provide innovative solutions for the protection, control and monitoring of generator assets. Generator protection is critical to maintaining maximum uptime in the generating facility and providing vital protection of the generating unit. From the protection and control of utility generators to ensuring safe interconnection of renewable energy sources, to synchronization and load shedding solutions using advanced automation, GE maximizes asset reliability and operational life.

GE’s advanced generator protection applications significantly reduce installation and maintenance costs by utilizing the Multilin HardFiber IEC 61850 process bus solution.
