ABB 1TGE120011R2200

Description

Product Description

The ABB 1TGE120011R2200 is a specialized protective relay module from ABB’s Relion® product family, specifically within the REF 620 series of feeder protection and control relays. This device is a Feeder Protection Relay designed for comprehensive protection, control, and monitoring of medium-voltage feeders and distribution networks. The 1TGE120011R2200 integrates multiple protection functions, measurement capabilities, and control logic into a single compact unit, serving as an intelligent electronic device (IED) for electrical distribution equipment. Implementing the ABB REF 620 relay (1TGE120011R2200) enhances the safety, reliability, and automation of power distribution systems.

Product Parameters and Specifications

• Product Type: Numerical Feeder Protection and Control Relay.
• Product Family: ABB Relion® REF 620 series.
• Key Protection Functions:
  • Overcurrent Protection (50/51, 50N/51N): Phase and ground overcurrent with definite and inverse time characteristics.
  • Directional Overcurrent (67/67N): For selective fault clearance in networked systems.
  • Voltage Protection (27/59): Under/over voltage protection.
  • Frequency Protection (81): Under/over frequency protection.
  • Breaker Failure Protection (50BF):
• Measurement: Three-phase currents, voltages, power, energy, power factor, and harmonics.
• Control: Programmable logic (CPL), remote and local control of switching devices (breakers, disconnectors).
• Communication Interfaces: Typically includes IEC 61850, Modbus RTU/TCP, and DNP3 for integration into substation automation and SCADA systems.
• Inputs/Outputs: Binary inputs for status monitoring and programmable binary outputs (relay contacts) for tripping, signaling, and control.
• HMI: Local graphical display and keypad for commissioning, control, and event review.

Advantages and Features

1. Integrated Multifunction Design: The ABB 1TGE120011R2200 consolidates protection, control, measurement, and monitoring into a single device. This reduces panel space, simplifies wiring, and lowers overall system cost compared to using separate relays, meters, and PLCs.
2. Advanced Communication for Modern Substations: Native support for IEC 61850 enables seamless integration into digital substation architectures, allowing for high-speed GOOSE messaging for interlocking and efficient communication with other IEDs and the station computer.
3. Flexible and Programmable Logic: The built-in Configurable Protection Logic (CPL) allows for extensive customization of protection schemes, control sequences, and interlocking without the need for external hardware.
4. Comprehensive Metering and Diagnostics: Provides detailed energy metering, power quality information, and extensive event and disturbance recording. This facilitates fault analysis, asset management, and preventive maintenance.
5. User-Friendly Configuration: The relay is configured using ABB’s PCM600 protection and control IED manager software, which offers an intuitive interface for setting management, logic configuration, and disturbance file analysis.

Application Cases in Various Fields

• Industrial Power Distribution: Protects and controls main incoming feeders, bus ties, and large motor feeders in factories, mines, and data centers.
• Utility Medium-Voltage Distribution: Serves as the primary protection for outgoing feeders in primary and secondary distribution substations.
• Renewable Energy Plants: Used for feeder protection at the point of interconnection (POI) for solar farms and wind parks.
• Commercial and Institutional Facilities: Provides protection for service entrances and critical feeders in hospitals, universities, and large office complexes.

Comparison with Competing Products

• vs. Electromechanical or Basic Digital Relays: Basic relays offer limited functions and no communication. The REF 620 (1TGE120011R2200) provides a full suite of protection, advanced communication, metering, and programmability, offering far greater functionality and system integration.
• vs. Using a PLC with Protection Functions: A PLC is not designed for high-speed, secure protection. The ABB 1TGE120011R2200 is a dedicated, certified protection device with hardware and firmware designed for reliable, deterministic response to electrical faults—a critical safety function.
• vs. Other Feeder Relays (e.g., Siemens 7SJ, GE Multilin F650): Competing relays offer similar core functionalities. The REF 620 is distinguished by its specific integration into the ABB Relion architecture, its user interface, and configuration within the PCM600 engineering ecosystem.

Selection Suggestions and Precautions

1. Protection Coordination Study Required: The relay settings must be derived from a detailed electrical system coordination study performed by a qualified protection engineer. Incorrect settings can cause nuisance trips or failure to operate.
2. CT and VT Specifications: Ensure your current transformers (CTs) and voltage transformers (VTs) are accurately specified and match the relay’s analog input requirements for ratio, accuracy class, and burden.
3. Communication Network Planning: Plan the communication architecture (cabling, network switches, SCADA addressing) early. For IEC 61850, proper system configuration with an SCD (System Configuration Description) file is essential and requires specialized knowledge.
4. Secure Configuration and Access: The relay is a critical component. Manage access passwords securely and maintain backups of all configuration files. Unauthorized access or configuration changes can compromise system protection.
5. Testing and Commissioning: Comprehensive testing using a primary injection test set or modern relay test set is mandatory before placing the 1TGE120011R2200 into service to verify all protection functions and settings.
