ABB SYNCHROTACT®5 Operating Instructions

General information
1.1 Introduction
This User Manual is aimed at persons who have a basic knowledge of working with
electronic equipment, who understand electrical symbols in schematic diagrams, but
who know little or nothing about working with SYNCHROTACT 5 equipment.
The User Manual provides the information required in order to install, commission and
operate the SYNCHROTACT 5 device of types SYN 5201 and SYN 5202.
1.2 Marking of text sections
General warning
This symbol placed before the text indicates situations or conditions which can cause a
risk of death or serious injury. The text describes the procedure for preventing these
risks.
Dangerous voltages
This symbol indicates that, when handling the equipment, dangerous voltages occur
which can cause death or serious injury.
The sections of text marked with "Caution" contain information on situations which can
lead to material damage or equipment failure if the instructions are disregarded.
The sections of text marked with "Note" provide additional information. This must be
taken into consideration in order to prevent malfunctions.

1.3 Purpose and use of the SYN 5201 and SYN 5202
The digital synchronizer can be used for the following applications:
• For automatic synchronization and paralleling of generators
• For automatic paralleling of synchronous and asynchronous lines, transmission lines
and busbars (incl. tap-changer matching).
• As a paralleling monitoring device (synchrocheck) for monitoring automatic or manual paralleling sequences including dead bus.


Brief description
The SYNCHROTACT 5 digital synchronizer is used for automatic synchronizing and
paralleling of generators with lines and for the paralleling of already synchronous lines.
The device is designed for system frequencies of either 50/60 Hz or 16 2
/3 Hz.
SYN 5201 is a single-channel synchronizing device whose component choice and
software design provides the highest security against incorrect paralleling.
SYN 5202 consists of two independent channels with different hardware and software.
This dual-channel property maximizes security against incorrect paralleling.
All parameters required for paralleling are stored in a parameter set. The paralleling
conditions and the characteristics of the voltage and frequency matchers are defined in
this set. With the option providing seven parameter sets, paralleling can be carried out
under different conditions or with different matcher characteristics using the same
device. Seven configurable digital inputs and outputs are available for the selection and
back indication of a parameter set.
The data which are important for commissioning and for control purposes can be
uploaded or downloaded using the PC tool SynView or, alternatively, via the keypad on
the front panel of the unit.
The following measured variables are generated from the two single-phase measuring
voltages:
Voltage U1, U2
U1 is the reference voltage e.g. line
U2 is the adjustable voltage e.g. generator.
Frequency f1, f2
f1 is the reference frequency
f2 is the adjustable frequency.
Voltage difference ΔU
ΔU = IU1I – IU2I
ΔU > 0 Adjustable voltage is lower
ΔU < 0 Adjustable voltage is higher
Slip s %100*121fs ff − =
s > 0 Adjustable frequency is less (e.g. generator is sub-synchronous)
s < 0 Adjustable frequency is greater (e.g. generator is oversynchronous)
Phase-angle difference α
21 ϕ ϕ α −=
α > 0 Adjustable frequency is lagging
α < 0 Adjustable frequency is leading
Acceleration ds/dt
[ ]ss dtdsxxx /%*2/
561∑==Δ=
(Every 0.5 s, an average value is formed from 56 measurements; sampling period: 9 ms)
ds/dt > 0 Adjustable frequency is reduced (e.g. generator accelerates)
ds/dt < 0 Adjustable frequency increases (e.g. generator is slowed down)
With SYN 5202, the measurement is carried out separately for each channel. It is
possible to carry out three-phase measurements in order to detect connection faults
(rotary field, polarity) and losses of phase.


Voltage measurement (SYN 5202: channel 1)
The two input voltages U1 and U2 are passed to the processor via high-impedance input
resistors, differential amplifiers, low-pass filters and A/D converters.
Voltage measurement channel 2 (SYN 5202 only)
The two input voltages U1 and U2 are passed through high-impedance input resistors
and differential amplifiers. The signal for the amplitude value is formed from this by
conversion and filtering . For zero-passage detection, the signal is filtered and passed
through a comparator. The signals prepared in this way are passed to the processor via
the A/D converter.

Frequency matcher with variable intervals
The function INVERSE f changes the way the frequency matcher functions. The pulses
are now always the same length, but the intervals are inversely proportional to the slip.
Pulse length: adjustable by means of the parameter tp fmin: tp = tp fmin
Pause interval: is calculated according to the following formula (can not be set as a
parameter):
2.2.3 Monitoring of paralleling conditions
The monitoring of the paralleling conditions can be divided into these parallel-functioning
blocks:
• voltage-carrying lines
• no-voltage lines
Paralleling of two voltage-carrying lines
The monitoring of the paralleling conditions enables a paralleling command (CHK
RELEASE) if the following conditions are fulfilled simultaneously:
• the phase-angle difference is within the tolerance band
• the slip is within the tolerance band
• the voltage difference is within the tolerance band
• the voltage does not fall below minimum voltage
• the maximum voltage is not exceeded
• the device is in operating status (OPERATING)
• nominal frequency deviation ≤ 5 Hz
Paralleling of no-voltage lines (dead bus)
A special case for the monitoring is the paralleling of no-voltage lines. A paralleling
command release is only issued if the external release signal is active and the
measuring logic enables the release at the same time. The release by the measuring
logic can be enabled if both voltages are within one of the permitted ranges. The dead
bus range can be defined as permissible for one, the other or both measuring voltages
by means of the parameters U1not, U2not and 1*2not.
The monitoring of the paralleling conditions (CHK RELEASE) releases the paralleling
command if the following conditions are fulfilled simultaneously:
• the releasing signal for dead bus (digital input) is issued
• the zero voltage(s) does not exceed the set threshold U0max
• the current voltage does not fall below the minimum voltage
• the current voltage does not exceed the maximum voltage
• the current zero voltage situation corresponds to a configuration permitted by means
of U1not, U2not, 1*2not
• the device is in Operating status (OPERATING)
2.2.4 Command generation
The command generation makes a distinction between asynchronous and synchronous
sources or no-voltage lines. Two modes, one for asynchronous and one for synchronous
sources, run in parallel, so that a source can be asynchronous or synchronous at any
time. The paralleling command is issued in the mode in which all conditions are fulfilled
first.
In SYN 5202 the actuation of the paralleling relays takes place separately in both
channels.
Asynchronous sources
It is called asynchronous sources, if the two lines to be paralleled (or generator and line)
are asynchronous before the circuit breaker is closed.
From the slip s, the acceleration ds/dt, the line frequency f1 and the set paralleling time
t on, the command generation calculates the necessary lead angle αv by which the
paralleling command is shifted forward in time so that the main contacts close exactly on
phase coincidence (see following figure)
