ABB REF615N microcomputer protection and control device

Description

The ABB REF615N Microcomputer protection measurement and control device is a high-performance digital multifunctional protection device, which is mainly used for the protection, control, measurement and monitoring of power systems. Here is a detailed description of the device:

Product Overview:
The REF615N is a member of the ABB Relion® product family of 615 protection and control devices, especially for feeder protection and control.
It can be used to protect utility substations and industrial distribution systems, including radiant, ring and grid distribution networks with or without distributed power sources.
The unit is compact and easy to disassemble, and is newly developed and designed based on the IEC 61850 standard to support interoperability and horizontal communication between the automation equipment in the substation.
Technical features:
Protection: The REF615N offers protection against a variety of fault types, including load faults, short circuit faults, ground faults, etc.
Measurement accuracy: The device has a very high measurement accuracy, up to 0.2.
High-speed switching capability: The circuit breaker can be triggered in a few milliseconds, ensuring that the system is protected in time in case of failure.
Protection functions: include overcurrent protection, ground protection, overvoltage protection, and undervoltage protection. These protection functions are fully configurable and can be set according to the specific application scenario.
Communication capability:
REF615N supports a variety of communication protocols, including IEC 61850 Version 2, IEC 61850-9-2 LE based process bus, IEC 60870-5-103, Modbus®, and others.
It has flexible data acquisition and control capabilities, which can realize real-time monitoring and control of remote equipment to ensure that the system can run in the optimal state.
Scope of application:
REF615N is widely used in all aspects of the power system, including substations, transmission lines, distribution lines, etc.
The device can be installed in a variety of different ways, such as wall mounted, steel frame type, installed in switches and circuit breakers, etc., to adapt to a variety of different installation occasions.
Main configuration and functions:
The REF615N is available in five optional standard configurations, and the standard signal configuration can be modified through the signal matrix or graphical configuration function of the PCM600 protection and measurement and control device management tool.
The application configuration feature allows you to create multiple layers of logic that can use many different logic elements, including timers and triggers.
The direction protection function takes the pointing line as the positive direction.
Other features:
The REF615N may also have an event logging feature to record events and failures that occur in the system for subsequent analysis and troubleshooting.
It may support remote monitoring and control functions, allowing operators to remotely monitor the status of the power system and perform necessary operations.
