2.Main functions

Power system protection:

RET670 can be used to protect generators,transformers,etc.in the power system from multiple faults such as overcurrent,overload,short circuit,etc.

For transformers,RET670 provides differential protection,overcurrent protection and other functions to ensure the safe operation of transformers.

Generator protection:

In power plants,RET670 can monitor and control the overcurrent,overfrequency,overvoltage and other parameters of the generator to protect the generator from damage.

System monitoring and data acquisition:

RET670 provides monitoring and data acquisition functions for the power system,which can be used to diagnose,record and analyze the operating status of the power system.

Communication interface:

RET670 has a communication interface,which can communicate with the monitoring system,SCADA system or other automation equipment to realize remote monitoring and control of the power system.

Integration into the automation system:

RET670 can be integrated into the automation control system of the power system to realize intelligent control of power equipment.

III.Technical features

Quick response:

RET670 has a fast response speed and can quickly cut off the fault circuit when a fault occurs to prevent the fault from expanding and equipment damage.

Flexible configuration:

Users can customize personalized protection plans according to actual needs and the characteristics of the power system.

High-precision measurement:

Using advanced digital signal processing technology,RET670 can measure electrical parameters such as current and voltage with high precision,and monitor and analyze the changes of electrical parameters in real time.

Differential protection function:

RET670 has a fast and low-impedance differential protection function,and the requirements for CT are very low.At the same time,the differential protection function has 2nd harmonic and waveform block suppression functions to avoid CT saturation and transformer surge current tripping.In addition,it also has 5th harmonic suppression function to avoid transformer overexcitation tripping.

Multiple low impedance limited earth fault protection functions:

RET670 provides multiple low impedance limited earth fault protection functions,including internal/external fault discriminator to improve safety.

IV.Application Field

ABB RET670 is widely used in power systems,power plants,substations,industrial enterprises and buildings,providing reliable support for the protection and control of power equipment.

The company mainly imports PLC modules, programmable controllers, servo control systems and DCS spare parts, such as ABB, AB (Rockwell), GE (General Electric), Bentley, Honeywell, Emerson, Motorola, Invensys, Westinghouse Electric, etc. The company has established close cooperative relationships with many world-renowned PLC and DCS product maintenance service providers.
