Figure 244: Circuit breaker control
If the ENA_CLOSE and BLK_CLOSE signals are completely removed from the breaker
control function block CBXCBR_52 with PCM600, the function assumes that the breaker
close commands are allowed continuously.
The sync check function SECRSYN1_25 is provided in this standard configuration. The
main purpose of the synchronism and energizing check is to provide control over the
closing of the circuit breakers in power networks to prevent the closing if the conditions
for synchronism are not detected. The energizing function allows closing, for example,
when one side of the breaker is dead.
The sync check function measures the bus and line voltages and compares them to set
conditions. When all the measured quantities are within set limits, the output SYNC_OK is
activated for allowing closing of the circuit breaker. The SYNC_OK output signal of
SECRSYN1_25 is connected to ENA_CLOSE input of CBXCBR1_52-1.
By default, Bus 1 is designated as the bus side and Bus 2 as the line side. Thus, LLDB
means that Bus 2 is live and Bus 1 is dead; similarly, LLLB means that both Bus 2 and 1
