5.4.1 Assigning several parameter sets to a paralleling point
This case applies if the same generator is paralleled with different matching
characteristics, e.g. in pump and turbine operation, or if SYNCHROTACT 5 is used both
as automatic synchronizing device and as synchrocheck for the same circuit breaker.
Example:
Two parameter sets are assigned to one paralleling point:
Input 1 is permanently selected. If a signal is applied to input IN2 before Start,
parameter set 2 is selected, otherwise parameter set 1 is active.
Programming:
Parameter I1 = 1
Parameter I2 = 9
Parameter O1 = 1
Operating behaviour:
Signal to: Outputs: Selected:
Input IN1 OUT1 closes Parameter set 1 and paralleling point 1
Inputs IN1 and IN2 OUT1 closes Parameter set 2 and paralleling point 1
Example: Parameter set for synchrocheck operation:
Two circuit breakers are normally automatically synchronized by means of parameter
sets 1 and 2. If, in addition to the signal at IN1 or IN2, a signal is applied to IN7,
parameter set 7 is linked with paralleling point 1 or 2. Parameter set 7 is parameterised
as synchrocheck. In synchrocheck mode, the output OUT7 connects the manual
paralleling switch in series with the paralleling release contact.
Definitions:
Parameter set 1 = automatic synchronization for circuit breaker 1
Parameter set 2 = automatic synchronization for circuit breaker 2
Parameter set 7 = synchrocheck for both circuit breakers
Connection as shown in figure below
Programming:
Parameter I1 = 1
Parameter I2 = 2
Parameter I7 = 14
Parameter O1 = 1
Parameter O2 = 2
Parameter O7 = 15
Operating behaviour:
Signal to: Outputs: Selected:
Input IN1 OUT1 closes Parameter set 1 and paralleling point 1
Input IN2 OUT2 closes Parameter set 2 and paralleling point 2
Inputs IN1 and IN7 OUT1 & OUT7
close
Parameter set 7 and paralleling point 1
Inputs IN2 and IN7 OUT2 & OUT7
close
Parameter set 7 and paralleling point 2
