EDR-5000
IM02602007E
PCC in HV systems
According to the
TranmissionCode 2007
[1]
the following condition has to be observed:
After decoupling of a DER caused by overfrequency, underfrequency, undervoltage, overvoltage or after isolated
operation, automatic synchronizing of the generators to the grid is only allowed under the following conditions:
The voltage in a 110 kV system is higher than 105 kV
The voltage in a 220 kV system is higher than 210 kV
The voltage in a 380 kV system is higher than 370 kV
The voltage values refer to the lowest voltage of the three phase to phase voltages.
It is required that the PCC and also the DER are equipped with a decoupling devices.
It is required that the decoupling device of the PCC controls the PCC's circuit
breaker.
It is required that the decoupling device of the power generation unit controls the
generator circuit breaker.
Reconnection
Conditions:
Before
reconnection
a power generation unit, it has to be secured, that mains voltage has been stabilized sufficiently.
For this a corresponding remote signal has to be available.
Set the parameter
»Reclosure Release Cond«
in the menu
[Protection Para\Set[x]\Q->&V<\Reclosure\Reclosure
Release] to
»
V Ext Release PCC«
.
The required parameter settings are described in the chapter
»General
Settings«.
Set the blocking signals in the menu
[Protection Para\Set[x]\Q->&V<\Reclosure\Reclosure Trigger] which start the mains recovery time
(OR logic).
Select a sufficient long recovery time »t1-Release Blo
« in the menu
[Protection Para\Set[x]\Q->&V<\Reclosure\Reclosure Release Cond].
Reconnection
is only possible after this
timer has been elapsed.
In the menu
[Protection Para\Set[x]\Q->&V<\Reclosure\Reclosure Release Cond]
the frequency range to be met
for reconnection can be set.
