High reliability and availability

The PDP800 supports full redundancy at all levels, including the PDP800 module, power supply, PROFIBUS DP link, and controller communication bus (HN800).

All redundancy options are independent of each other to ensure the highest level of availability and reliability.

Data Accessible to Control Applications

The functionally coded control application in the Symphony Plus controller has access to PROFIBUS device cycle data.

The data can be calculated, used as part of a control strategy, or displayed and alarmed at the S+ operator console.

An overview of the functions of the PDP800 is shown in Figure 2.

Managing Intelligent Field Devices

PROFIBUS devices are fully integrated into the Symphony Plus system, bringing benefits that go far beyond reduced footprint and cable costs.

In the S+ Engineering Workbench, field engineering tools support configuration, commissioning and maintenance of PROFIBUS devices using Device Type Manager (DTM) technology.

For field devices with a conventional device description file (GSD), standardised configurations are possible using the basic PROFIBUS DTM.

Individual device DTMs can be accessed from multiple data views (e.g. system or location overview, etc.) in Composer.

It includes automatic calculation of net values and loading of process items by using the device-specific channel configuration generated from the DTM.

Comprehensive I/O Support

The PDP800 module connects Symphony Plus controllers to the S800 I/O via PROFIBUS DP V2. The S800 I/O offers options for all signal types.

The S800 I/O offers options for all signal types, from basic analogue and digital inputs and outputs to pulse counters and intrinsically safe applications.

PROFIBUS DP V2 supports the S800 I/O Event Sequence function, which time stamps events at the source with a 1 ms accuracy.

In addition, the PDP800 supports the connection of Symphony Plus controllers to S+ Turbine dedicated modules.

Specifically, via PROFIBUS DP V2. the HPC800 supports powerful turbine control solutions.

such as turbine protection (TP800), valve positioning (VP800), automatic synchronisation of generators (AS800) and condition monitoring (MCM800).

With fibre-optic extension, PROFIBUS I/O modules and devices can be placed up to 15 km away from the PDP800.

In addition, the PDP800 modules can be located up to 3 km away from the controller via redundant HN800 fibre optic communication.

Seamless Intelligent Field Device Integration

SD Series PDP800: Redundant Configuration

Overview

RET615 is a dedicated transformer protection and control relay for power transformers,

unit and step-up transformers including power generator-transformer blocks in utility and

industry power distribution systems. RET615 is a member of ABB’s Relion® product

family and part of its 615 protection and control product series. 

The 615 series relays are characterized by their compactness and withdrawable-unit design.

Re-engineered from the ground up, the 615 series has been designed to unleash the full

potential of the IEC 61850 standard for communication and interoperability between

substation automation devices. Once the standard configuration relay has been given the

application-specific settings, it can directly be put into service.

The protection relay can support five simultaneous clients. 

If PCM600 reserves one client connection, only four client connections are left, for example, for IEC 61850 and Modbus.

All communication connectors, except for the front port connector, are placed on

integrated optional communication modules. 

The protection relay can be connected to Ethernet-based communication systems via the 

RJ-45 connector (100Base-TX) or the fiber optic LC connector (100Base-FX).

Protection functions

The protection relay offers integrated protection functions including two-stage 

overvoltage and undervoltage protection, two-stage residual overvoltage protection, 

as well as singlestage negative phase-sequence overvoltage protection and 

single-stage positive phase-sequence undervoltage protection.

Measurement

The protection relay physically measures the three phase-tophase voltages and the residual voltage of the power system.

Further, from the phase-to-phase voltages the protection relay

calculates the positive and negative phase-sequence voltages,

the one-minute average phase-to-phase voltage, the average

phase-to-phase voltage for a user-specifiable time frame, the

maximum value of the one-minute average voltage, and the

maximum and minimum phase-to-phase voltage value since last reset.

The values of the voltages measured or calculated can be

accessed locally via the user interface on the protection relay’s

front panel, or remotely via the serial communication interface

on the rear panel of the protection relay.

Disturbance recorder

The protection relay is provided with a built-in battery backedup digital 

disturbance recorder for four analog signal channels and eight digital signal channels. 

The analog channels can be set to record the curve form of the voltages measured. 

The digital channels can be set to record external or internal relay

signals, for example the start or trip signals of protection relay’s

stages, external blocking or control signals. Any digital relay

signal such as a protection start or trip signal, or an external

relay control signal can be set to trigger the recording. 

The recordings are stored in a nonvolatile memory from which the

data can be uploaded for subsequent fault analysis.

Description

REU610 is a voltage protection relay for system voltage

protection, measuring and supervising in utility and industrial

power systems. REU610 is a member of ABB’s Relion®

protection and control product family and part of its 610

product series. The 610 series includes protection relays for

feeder protection, motor protection and general system voltage

supervision. The plug-in design of the 610 series protection

relays facilitates the commissioning of the switchgear and

enables fast and safe insertion and withdrawal of relay plug-in units.

The protection relay is primarily designed for the overvoltage

protection of power system components, such as busbars,

feeders, power transformers and capacitor batteries. It is also

used for the general power system earth-fault supervision.

Further, the protection relay can be used for undervoltage

protection of motors and overvoltage protection of capacitor

batteries, for initialization of automatic busbar changeover and

disconnecting small power units from the network in case of a

major network disturbance. The 610 series protection relays

are suitable for employment in marine and offshore environments.

The numerical voltage protection relays of the 610 series

support a wide range of standard communication protocols,

among them the IEC 61850, IEC 60870-5-103, DNP3, Modbus,

Profibus, LON and SPA communication protocols.

Measurement

The relay continuously measures phase currents and earth current. Earth current can be

measured using external core balance current transformer or can be calculated internally.

The relay has provision to display measured three phase current and earth current in primary

and secondary terms. Additionally, relay displays status of binary input, binary output and trip

counter for over current and earth fault trip.

During service, the default view of display shows three phase current and the earth current in

secondary terms. The values measured can be accessed using on the local HMI.

Event log 

To collect sequence – of – events (SoE) information,

the relay incorporates a non-volatile memory with a capacity of storing 250 events

with associated time stamps with resolution of 1 ms.

Event log includes protection operation status, binary I/O status and relay fault code.

The event logs are stored sequentially,the most recent being first and so on.

The non-volatile memory retains its data also in case the relay temporarily loses its auxiliary supply.

The event log facilitates detailed post-fault analysis of feeder faults and disturbances.

The SoE information can be accessed locally via the user interface on the relay front panel.

Application

The REJ603 is a protection relay aimed at selective short-circuit and earth-fault protection

of feeders in secondary distribution networks and for protection of transformers in utilities and industries.

The inrush current stabilization function allows the relay to be used as main protection of

distribution transformers.

The relay is powered up through current transformer if current is above energizing level of

relay, front USB power or through auxiliary supply (optional feature).

The relay offers, non-directional over current and earth-fault protection. 

The residual current for the earth-fault protection is derived from the phase currents. 

When applicable,the corebalance current transformers can be used for measuring the residual current,

especially when sensitive earth-fault protection is required.

The relay additionally offers thermal overload protection for feeders, cables and transformers.

There is optional provision of remote trip through binary input with external auxiliary power supply.

The remote trip signals like transformer trouble output (Buchholz, Oil temperature,

Winding temperature trip) or an external trip can be wired

to binary input. The remote trip function works even in CT-powered mode when auxiliary supply

is not available but enough CT current is available to power-up the relay.

Protection functions

REJ603 offers three-stage overcurrent and twostage earth-fault protection functions.

The transformer inrush detector function is incorporated to prevent unwanted tripping’s due to energizing of transformers.

The low-set stages for overcurrent and earthfault protection are equipped with selectable characteristics – Definite time (DT) and Inverse

definite minimum time (IDMT).

The relay featuresstandard IDMT characteristics according IEC 60255-151. Normal Inverse (NI), Very Inverse (VI),

Extremely Inverse (EI), Long-time Inverse (LI) and IDMT characteristics as per ANSI C37.112 Moderate inverse,

Normal Inverse, Very inverse, Extremely inverse.

The relay also has special characteristics like RI, HR and FR fuse,which allows better co-ordination with the rest of the network.

Further relay offers thermal overload protection for feeder, cable and transformer.
