SYNCHROTACT® Systems

Application

SYNCHROTACT® synchronizing cabinets can be designed specifically for customer requirements and are

used to synchronize generators and to parallel lines.

Depending on available space, other systems, as for example measuring and metering functions, may be

used in the same cabinet, in addition to the synchronizing system.

SYNCHROTACT® Systems

Typical configurations of a synchronizing system

The system uses proven SYNCHROTACT® 5-components

and may be individually adapted. Typical configurations are as follows:

1. Safety: Single- or dual-channel solutions

2. Availability: Redundant manual synchronizing or redundant

automatic synchronizing or both

3. Number of circuit breakers to be synchronized: up to four circuit

breakers, one or more of which may be generator breakers

4. Power supply: In case of redundant synchronizing, the

power supply on the cubicle entrance can be redundant too.

5. Synchronizing control: Remote, local or both

6. Adaptation of the measuring voltages: Especially with

synchronizing of several circuit breakers it may occur that the

two secondary voltages have different amplitudes and

phase angles with closed circuit breaker.

Examples of synchronizing concepts

Automatic synchronizing (sketch shows dual channel version)

including separate synchrocheck for redundant manual

synchronizing (with its own hardware and power supply).

Functionality

SYNCHROTACT® CSS supports the following operating

modes, which can be selected by means of a switch.

– Operating mode AUTO: generator voltage and frequency

are automatically matched by the synchronizing equipment.

The circuit breaker will be closed subsequently and exactly

with phase-coincidence, taking the breaker closing time into

consideration.

– Operating mode MAN: the functions are carried out

manually by means of push buttons on the front panel.

The necessary values are displayed on the synchronizing

instruments. The paralleling command is issued by holding

down the release button and pushing the command button if

phase-coincidence is reached.

– Operating mode TEST: this is identical to the AUTO-mode,

except for the paralleling command which is not sent to

the circuit breaker but displayed by the system only.

With models for two circuit breakers the paralleling point has

to be selected by means of the appropriate selector switch

before the synchronizing process is started.

Releasing by means of a key switch, the circuit breaker can

be closed even if one or both measuring voltages are dead

(dead bus).

Changing the control mode selection from «local» to «remote»

allows the use of automatic synchronizing from a remote location.

SYNCHROTACT® CSS Application and functionality

SYNCHROTACT® CSS (Compact Synchronizing System) is a

pre-engineered synchronizing system, sold as a product.

Application

The use of the already planned and tested synchronizing

system saves all engineering costs and inreases safety.

SYNCHROTACT® CSS only needs to be installed, connected

and commissioned.

The system uses the proven and reliable SYNCHROTACT® 5

components and can be built into a 19″ frame.

To ensure high availability of the plant, SYNCHROTACT®

CSS consists of a fully automatic and independent manual

synchronizing unit.

Different versions are available, either for one or for two

circuit breakers, and both either in single- or dual-channel

configuration.

The PC software, SynView, which is included in the delivery,

provides quick and simple commissioning.

If possible, the compensation should be done in a way

that a single phase compensation VT is required only

If there is a step-up transformer between measuring VT and

circuit breaker, the connection group is usually Yd1 (+30 DEG)

or Yd11 (-30 DEG).

With the appropriate selection of the phases, the phase shift

can be compensated without any additional components. In

this example the compensation of the amplitude by factor √3

remains. This can be done by a single phase compensation VT.

In order to achieve higher accuracy, especially if higher load

(synchronizing instruments) is connected, the compensation

should be carried out on the generator side.

If a three-phase compensation is inevitable, 3 single-phase VTs

have to be selected which will then be connected according

to the needs. Be aware that the single phase ratio has to

be calculated.

When are adaptation or compensation VTs needed?

– If the two nominal measuring voltages are out of admissible

range (50 to 130 VAC).

– If the two nominal measuring voltages are different. With

the types SYN 5200 and SYN 5201. differences between

the nominal values up to 10 % can be tuned by parameter

setting. – If there is a step-up transformer between measuring VT and

circuit breaker, which shifts the phase by a fixed value, it

can be compensated with types SYN 5200 and SYN 5201.

With the types SYN 5100. SYN 5202. SYN 5302. or with

the use of electromechanical synchronizing instruments,

compensation VTs shall be used in order to compensate for

the phase shift.

If a three-phase compensation is inevitable, 3 single-phase VTs

have to be selected which will then be connected according

to the needs. Be aware that the single phase ratio has to

be calculated.

or alternatively, four paralleling points, each with eight contact

pairs. Several devices can be used at the same time.

Electromechanical instruments are commonly used if the

synchronizing system provides a manual synchronizing

feature. Sometimes the instruments are used in automatic

synchronizing systems for information only, eg, for servicing

purposes. This requirement can also be covered by the

SYNCHROTACT® 5 PC-tool SynView.
