GE/ ALSTOM GENERATOR PROTECTION RELAY MICOM P344

GE’s MiCOM Agile P34x generator protection relays provide flexible and reliable integration of protection, control, monitoring, and measurement functions for a wide range of applications. The P34x relay platform is available in seven 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.

Key features of Micom P344 Generator Protection Relay:

• Comprehensive, flexible communications options with a number of protocols and ports available
• User-friendly programmable scheme logic allows easy customization of the protection and control functions
• Binary inputs offer programmable pickup voltage thresholds and filtering enabling a truly universal application
• High break output contacts eliminate reliance on auxiliary devices
• Unique low-frequency protection for variable speed double fed induction machines
• Rotor earth fault protection

GE‘s Agile P34x generator protection solutions provide extensive functionality to meet all generator and generator – transformer applications, including differential protection for fast and selective tripping of phase and earth faults. All generator protection, control, monitoring, recording, and communications components are housed within one box, and the solutions are accompanied by a comprehensive library of hardware options, protection, and control functions to meet system requirements.

Key benefits:

• Extensive condition based monitoring features for generators and transformers
• Graphical programmable scheme logic eases protection scheme creation and avoids the need for external logic controllers
• Range of different protocols (MODBUS, DNP3, IEC 60870-5-103, and IEC 61850) are available
• IEC 61850 / DNP3.0 redundant Ethernet, supporting self healing ring, RSTP, dual homing, or PRP
• Programmable curves for easy protection customization

Main characteristics:

• Sensitive rotor earth fault protection using low frequency injection method
• Harsh Environment Option to protect against corrosive gases such as H2S or SO2
• Generator and transformer thermal overload, transformer loss of life, and through fault monitoring
• Extensive protection for large machines such as pole slipping and 100% stator earth fault protection (3rd harmonic and low frequency injection method)
