Editorial
SIPROTEC more than just protection
This is the latest edition of the printed SIPROTEC Catalog. This
edition - which is now available - contains many suggestions by our
readers, along with information regarding innovations and supple-
mentary products. The SIPROTEC Catalog is also available on
CD ROM.
One of the new highlights is the SIPROTEC protection relays with
IEC 61850 communication. IEC 61850 was created by relay experts
and manufacturers alike. The goal of this standard is to achieve an
object-oriented communication structure within substations.
SIPROTEC protection relays and bay control units are the first to
feature the IEC 61850 standard. With the substation configurator, a
part of DIGSI 4, SIPROTEC units as well as other makes can be
configured in accordance with IEC 61850.
This SIPROTEC Catalog is supplemented by multimedia computer
animation tools.

SIPROTEC 7RW600Numerical Voltage, Frequency and Overexcitation Protection Relay
The SIPROTEC 7RW600 is a numericalmultifunction protection relay for connec-tion to voltage transformers. It can be usedin distribution systems, on transformersand for electrical machines. If theSIPROTEC 7RW600 detects any deviationfrom the permitted voltage, frequency oroverexcitation values, it will respond ac-cording to the values set. The SIPROTEC7RW600 can be used for the purposes ofsystem decoupling and for load shedding ifever there is a risk of a system collapse as aresult of inadmissibly large frequencydrops. Voltage and frequency thresholdscan also be monitored.
The SIPROTEC 7RW600 voltage,frequency and overexcitation relay can beused to protect generators and transform-ers in the event of defective voltage control,of defective frequency control, or of fullload rejection, or furthermore islandinggeneration systems.
This device is intended as a supplement toSiemens substation systems and for use inindividual applications. It has two voltageinputs (V; Vx) to which a variety of func-tions have been assigned. While input Vserves all of the implemented functions,input Vx is exclusively dedicated to thevoltage protection functions. The scope offunctions can be selected from threeordering options.

11/81
The SIPROTEC 7RW600 relay contains, ina compact form, all the componentsneeded for:
Acquisition and evaluation of measuredvalues
Operation and display
Output of messages, signals andcommands
Input and evaluation of binary signals
Data transmission (RS485) and
Auxiliary voltage supply.
The SIPROTEC 7RW600 receives AC volt-ages from the primary voltage transformer.The secondary rated voltage range, 100 to125 V, is adapted internally on the device.
There are two device variants available:
The first version, for panel flushmounting or cubicle mounting, has itsterminals accessible from the rear.
The second version for panel surfacemounting, has its terminals accessiblefrom the front.
Fig. 11/78Rear view of surface-mounting case
Overvoltage protection
The overvoltage protection has the func-tion of detecting inadmissible overvoltagesin power systems and electrical machinesand, in such event, it initiates systemdecoupling or shuts down the generators.
Two voltage measuring inputs (V, Vx) areprovided on the unit. These must be con-nected to two phase-to-phase voltages. Theinput voltages are processed separately intwo two-stage protective functions. Fromthese, two principle connection variantsare derived.
Fig. 11/81, Fig. 11/82, and Fig. 11/83, onpage 11/83, show the following connectionexamples:
Fig. 11/81:Separated connection, used for overvoltageprotection and earth-fault detection
Fig. 11/82:Two-phase connection to a voltagetransformer
Fig. 11/83:Alternative V connection
Undervoltage protection
The main function of the undervoltageprotection is protecting electrical machines(e.g. pumped-storage power generatorsand motors) against the consequences ofdangerous voltage drops. It separates themachines from the power system and thusavoids inadmissible operating states andthe possible risk of stability loss. This is anecessary criterion in system decoupling.
To ensure that the protection functions ina physically correct manner, when used inconjunction with electrical machines, thepositive-sequence system must be evalu-ated.
The protection function can be blocked,via a binary input, causing a drop in ener-gizing power. The auxiliary contact of thecircuit-breaker can be used for this pur-pose with the circuit-breaker open. Alter-natively, undervoltage acquisition can beactivated on a conductor-separated basis(V

Overexcitation protection
The overexcitation protection detects andrecords any inadmissibly high induction

f
in electrical equipment, e.g. generators ortransformers, that may occur as a result ofa voltage increase and/or frequency drop.Increased induction of this nature maylead to saturation of the iron core, exces-sive eddy current losses, and thus to inad-missible heating.
It is recommended to use the overexcita-tion protection function in power systemssubject to large frequency fluctuations(e.g. systems in island configuration orwith weak infeed) and for electrical blockunits that are separated from the system.
The overexcitation protection functioncalculates, from the maximum voltage (V,Vx) and the frequency, the ratio V/f. Thisfunction incorporates an independentwarning and tripping stage and a curvewhich is dependent on and adaptable tothe object to be protected and which takesdue account of the objects thermal behav-ior. Incorrect adaptation of the voltagetransformer is also corrected. The over-excitation protection function is effectiveover a broad frequency range (25 to 70 Hz)and voltage range (10 to 170 V).

Features
Fig. 11/80 Wiring communication
Serial data transmission
The SIPROTEC 7RW600 relay is fittedwith an RS485 port, via which a PC canbe connected, thus providing, in con-junction with the DIGSI operating andanalysis program, a convenient tool forconfiguring and parameter setting. TheDIGSI program (which runs underMS-Windows) also performs fault re-cording and fault evaluation. TheSIPROTEC 7RW600 relay can also belinked, via the appropriate converters,either directly or over an optoelectronicconnection (optical fiber) to the interfaceof the PC or substation control system(IEC 60870-5-103 protocol).
