The REG670 is one of the flagship products within this series, focused specifically on generator protection.

3. Key Features and Functions**

a. Core Protection Functions:
The REG670 is designed as the “guardian” of the generator, integrating dozens of advanced protection functions, including but not limited to:

• Differential Protection: Rapidly clears internal phase-to-phase short-circuit faults in the generator.

• Stator Earth Fault Protection: Detects single-phase earth faults in the generator stator winding.

• Rotor Earth Fault Protection: Detects earth faults in the generator excitation winding.

• Loss of Excitation Protection: Prevents the generator from losing synchronism due to excitation failure, which could lead to system instability.

• Reverse Power Protection: Prevents the generator from operating as a motor, which could damage the prime mover (e.g., steam turbine, hydro turbine).

• Overload Protection: Protects the generator from overheating due to excessive current.

• Overvoltage/Undervoltage Protection:

• Overfrequency/Underfrequency Protection:

• Out-of-Step Protection: Determines and takes appropriate action during power system oscillations.

• Backup Protection: Provides backup protection for adjacent equipment (e.g., transformers, busbars).

b. Control and Monitoring Functions:

• Automation Functions: Supports sequential control, automatic synchronizing, load sharing, etc.

• Measurement and Metering: Monitors all key electrical quantities in real-time, such as voltage, current, active/reactive power, power factor, frequency, and energy.

• Fault Recorder: Records detailed data before, during, and after a fault for event analysis.

• Event Recording: Logs all operations, alarms, and state changes with precise timestamps.

• Condition Monitoring: Monitors the status of primary equipment like circuit breakers and disconnectors.

c. Communication and Integration:

• Multiple Communication Protocols: Supports industry-standard protocols such as IEC 61850 (GOOSE and MMS), IEC 60870-5-103/104, Modbus, etc., enabling seamless integration into modern digital substation and control systems.

• Powerful I/O Capability: Offers a large number of analog and digital input/output modules, allowing for flexible configuration to meet various application requirements.

• HMI Interface: The front panel is equipped with a large LCD display and navigation keys for easy on-site data viewing and parameter setting.

4. Typical Applications

This relay is primarily used in large-scale power generation applications requiring high reliability:

• Steam Turbine Generators in Thermal Power Plants (coal-fired, gas-fired)

• Hydroelectric Generators in Hydroelectric Power Plants

• Generating Sets in Nuclear Power Plants

• Industrial Power Plants (e.g., captive power plants in industries like paper, petrochemical)

• Large Generator-Transformer Units (Unit-connected generators)
