8.3.2 Function tests
Checking the voltage matchers
While checking the voltage matchers, the command circuit of the circuit breaker should
be interrupted for safety reasons (bring machine circuit breaker to Test position, draw
out the carriage, pull command relay or unplug paralleling relay connector -X6 on the
rear of the device). Otherwise, the plant should be ready for operation.
 Manually set generator voltage to a value below the line or busbar voltage.
 Start SYNCHROTACT 5. The voltage and frequency matchers now attempt to match
the voltage and frequency . The frequency matchers can be switched off temporarily
(df/dt = 0) to allow the working of the voltage matchers to be better observed.
If an error message appears on the LCD, proceed in accordance with the fault list.
If the parameters
Umax, dU/dt, ts U and tp Umin are set correctly, a single adjusting
command U+ is sufficient in order to achieve the tolerance band, assuming that the
excitation is functioning in a stable manner.
The matching procedures should be repeated and observed several times, starting from
different working points. If oscillations occur, the setting value dU/dt should be increased
until no further oscillations occur. It is also possible to repeat the test function “TEST U-
Match“.
Checking the frequency matchers
For safety reasons, interrupt the command circuit of the circuit breaker (bring machine
circuit breaker to Test position, draw out the carriage, pull command relay or unplug
paralleling relay connector -X6 on the rear of the device). Otherwise, the plant should be
ready for operation.
 Manually set generator frequency to a value below the line or busbar frequency.
