ABB REG216/REG216 Classic digital generator protection

ABB REG216/REG216 Classic digital generator protection

Product Overview

ABB REG216/REG216 Classic is a digital generator protection system designed specifically for the protection of generators and block transformers. It adopts modular hardware and software design, with extremely high installation flexibility. By combining software libraries with hardware modules, it can easily adapt to primary systems and protection solutions of different scales, providing cost-effective solutions in various application scenarios. There are two design versions of the system, with the main difference being the modules used for binary process connections: REG216 uses the E/A module 216GD61a, while REG216 Classic uses the 216GE61/216GA61 and 216GA62 modules.

Core functions and protection functions

The system has a rich library of protection functions, covering various functions required for generator and transformer protection, mainly including:

Differential protection: such as generator differential (87G) and power transformer differential (87T), suitable for three-phase and 2-3 winding transformers.

Current protection: including timed overcurrent (51), overcurrent or undercurrent with peak evaluation (50), voltage controlled overcurrent (51/27), etc.

Voltage protection: There are timed overvoltage (59), undervoltage (27), instantaneous overvoltage protection (59, 27), etc. It can also be used for stator grounding faults, rotor grounding faults, and other protections.

Other protections: such as negative sequence current protection (46), distance protection (21), power protection (32, 37), frequency protection (81), overheating protection (49), etc.

These protection functions can be selected from a comprehensive library through a personal computer, without the need for computer programming knowledge, and have a wide range of settings. The main parameters can be flexibly set.

Hardware composition

Main components: The system includes interfaces with the primary system (CT, PT, and auxiliary relays) as well as parallel buses and related electronic units (such as analog inputs and data processors), which are connected through standard prefabricated shielded cables.

Interface component: Input transformer component 216GW62 is used to adjust signal level and provide isolation; Auxiliary relays and optocoupler components are used to achieve functions such as potential separation and tripping of digital input and output signals.

Electronic unit: adopting a plug-in design, installed in a 19 ", 6U standard size equipment rack, including processing unit 216VC624, analog input unit 216EA62, digital output unit 216AB61, etc., data exchange is carried out through parallel bus B448C.

Setting and Control

Operation method: Set up and control through a personal computer connected to a serial interface. Console operation is assisted by menus, allowing for parameter settings, measurement value display, event display and printing, fault recording, and other operations.

Software Tools: Starting from firmware version V5.2, a Windows based configuration tool CAP2/316 is available, which can run on specific operating systems and supports online or offline programming.

Self monitoring and testing

Self monitoring: including continuous self-monitoring of hardware and periodic testing programs primarily executed by software.

Testing function: Various operational measurement data can be viewed, simulated numerical testing can be conducted through the "testing function" of the software HMI, and external testing equipment can be used for injection testing to achieve 100% system testing.

Redundant configuration

Hardware and software redundancy can be adjusted according to functional requirements, and two independent protection function groups can be installed in two separate hardware racks, or in only one rack but with two completely independent hardware groups.

Technical parameters

Input circuit: The rated current is 1A, 2A, or 5A, the rated voltage is 100V or 200V, the rated frequency is 50/60Hz, and there are corresponding parameters such as thermal rating.

Parameters of each protection function: Different protection functions such as generator differential, transformer differential, timed current function, etc. have their own technical parameters such as setting range, accuracy, response time, etc.

Other parameters: such as auxiliary power supply, general data (temperature range, humidity, seismic testing, etc.), mechanical design parameters, etc.

Order Information

Configuration information: When ordering, please provide information such as rated current, rated voltage, optocoupler voltage, number of different units (electronic parts) and interfaces, and refer to questionnaire 1MRB520026-Ken.

Subcode: The system has multiple subcodes corresponding to different system configurations, rated parameters, interface arrangements, etc., which can be selected according to requirements.

Attachments: including DC filter, PCC card interface, RS232C bay bus interface, human-machine interface, fiber PC connection cable, fault recorder evaluation program, etc.
