Protocol Modbus RTU

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 diffe rence), 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.
