ABB SYNCHROTACT® Datasheet Synchronizing devices and systems

From:ABB | Author:Wang | Time :2025-01-06 | 212 visit: | Share:

ABB Switzerland Ltd is a world-leading

manufacturer of synchronizing equipment.

Application-specific systems are developed,

produced and commissioned. In addition, our

products are supported throughout the entire

lifecycle.

The product portfolio of SYNCHROTACT® offers enormous advantages

+ Optimum reliability

+ Guaranteed availability

+ Lowest project-engineering costs

+ Quick commissioning using PC tool SynView

+ Synchronizes up to seven power circuit breakers with different

requirements

+ Advanced technology

+ Universal use

+ Decades of experience with synchronizing systems

+ After-sales service: a 24 hour hotline available 365 days a

year and remote servicing via the Internet

+ Training program for commissioning and service personnel

Synchronizing devices are widely used in power stations or

industrial installations with their own power generating facilities,

where the generators need to be paralleled with an island line

or a public line, or in power distribution systems.

Power circuit breakers may only be closed if both voltages are

approximately synchronous (coincident). Otherwise, faults in

line operation, loading of the generators and, in extreme cases,

damage to the generators can result.

SYNCHROTACT® 5 performs these functions safely and reliably,

whether as a monitoring element for manual paralleling or as

an independent fully-automatic synchronizing device.

The synchronizing and paralleling process can be divided

into the following blocks

Measuring

Voltage difference ΔU (amplitude), slip s (frequency difference), and phase-angle α, are all required for paralleling.

These values are formed from the two measurement signals

U1 and U2 (see illustration, left).

Matching

Voltage and frequency matching functions reduce the voltage

difference ΔU, and slip s by sending adjusting pulses to the

voltage or turbine regulators.

Monitoring of paralleling conditions

This function compares the actual values with their set

maximum values and releases paralleling (CHK RELEASE) if

all conditions are fulfilled simultaneously.

Synchrocheck mode (paralleling monitoring)

In synchrocheck mode, only the measuring and monitoring

function blocks are active. The output relay is closed during

paralleling release.

Command generation

The command generation calculates the necessary lead angle

αv, by which the paralleling command must be advanced

due to closing time delay. The action ensures that the main

contacts close at precisely the right time. If α reaches αv at

the same time as paralleling release (CHK RELEASE), the

command is issued. Under synchronous conditions, ie,

permanent paralleling release during the adjustable monitoring

time, tsup, the CMD is also issued without taking the lead

angle into consideration.

From a synchronizing device, it is expected to close the

power circuit breaker at the correct time but also that, if

required, paralleling can take place whenever permissible.

Although the series connection of the output contacts of two

independently-functioning channels (dual-channel system),

which is usual in synchronizing systems, greatly increases

security against incorrect paralleling, it necessarily leads to a

reduction in availability.

Single or dual-channel?

Not every synchronizing system needs to be structured

according to the above pattern. The SYNCHROTACT® 5

single-channel synchronizing devices offer a high degree of

security and are often used in practice. However, security

can be significantly increased by means of dual-channel

systems. It is unlikely that the two channels - of which the

hardware and software are structured differently - will have

the same malfunction simultaneously. The extra cost of a

dual channel system can prove beneficial compared to the

damage arising from incorrect paralleling.

Second, redundant synchronizing system?

Often, two redundant synchronizing systems are installed

in a single plant so that, in the event of one system failing,

the other can be used, thereby increasing availability. The

second system is often designed for manual synchronizing

with or without synchrocheck.

In addition, with SYNCHROTACT® 5, ABB offers two automatic

dual-channel systems in a single casing, thus avoiding

manual synchronizing.

Advantages of such a solution:

– No engineering and wiring costs for the second system

– Further increased security since all four output contacts

are normally operated in series

– No problems with synchronizing where the

manual synchronizing system is seldom used.
