ABB REM615 HBMBCCAHNBA1ANN1XD

Key Features and Functional Highlights:

• All-in-One Solution: Integrates motor protection, control, measurement, and monitoring functions, reducing the need for separate devices and simplifying system architecture.
• IEC 61850 Native Support: Designed from the ground up to support IEC 61850 Edition 1 and 2, including GOOSE (Generic Object Oriented Substation Event) messaging for fast horizontal communication and IEC 61850-9-2 LE for sampled values over process bus.
• Advanced Redundancy: Supports high-availability network protocols such as HSR (High-availability Seamless Redundancy) and PRP (Parallel Redundancy Protocol), ensuring zero-time recovery in case of network failures.
• Precise Time Synchronization: Features support for IEEE 1588 v2 (PTP), SNTP, and IRIG-B for high-precision time synchronization across the substation.
• Flexible Configuration: Available in four standard configurations (A, B, C, J) that can be easily customized using ABB’s PCM600 configuration tool. Users can create complex logic using timers, triggers, and multi-level logic blocks to meet specific application needs.
• User-Friendly Interface: Equipped with a large graphical LCD display that shows a customizable single-line diagram (SLD). It can be accessed locally or remotely via a web browser-based HMI.
• Plug-in Design: Features a withdrawable plug-in unit for swift installation, testing, and maintenance, minimizing downtime.
• Comprehensive Self-Supervision: Continuously monitors its own health, including trip circuit integrity, CT/PT circuit status, and internal diagnostics.

Protection and Control Functions:

The REM615 provides a wide array of protection functions, configurable based on the selected standard configuration:

• Standard Motor Protection:
  • Thermal Overload Protection (ANSI 49): Simulates motor heating based on current and thermal capacity.
  • Locked Rotor / Stall Protection (ANSI 48/51LR): Detects excessive current during motor start-up or running.
  • Start-up Time Supervision: Monitors the time taken for the motor to accelerate.
  • Reversal / Phase Failure Protection (ANSI 46): Detects negative sequence currents.
  • Load Loss / Underload Protection: Detects when a motor is running without a load.
• Electrical Protection:
  • Overcurrent Protection (ANSI 50/51): Instantaneous and time-delayed phases and ground fault protection.
  • Voltage Protection (ANSI 27/59): Undervoltage, overvoltage, and phase sequence protection.
  • Frequency Protection (ANSI 81): Overfrequency and underfrequency protection with rate-of-change (df/dt) detection.
• Optional/Advanced Functions:
  • Arc Flash Protection: Can be equipped with high-speed inputs for arc light sensors to quickly clear internal faults.
  • Sensitive Earth Fault Protection: Utilizes core balance CTs or summation of phase currents.
  • RTD and mA Input: Optional module for direct measurement of motor winding and bearing temperatures (up to 6 RTDs and 2 mA inputs).
