Valid for packages 1 and 2 of easYgen-3400/3500:
The operating range monitor checks additionally the plausibility of generator and busbar, if
GCB is closed. Refer to
ª “General notes” on page 193
for details.
The Generator “Unload mismatch" monitor (
ª Chapter 4.4.3.6 “Engine/Generator
Unloading Mismatch” on page 190
) from now on
–is usable in Application mode "None".
–includes all alarm classes and a self reset feature.
All monitoring functions with enabled setting “Delayed by engine speed”, can be blocked
with a LogicsManager equation. Refer to
ª Chapter 4.5.9.3 “Engine Start/Stop”
on page 299
for details.
The power factor monitoring is activated, if the generator current expires 5% rated Gener‐
ator current. The monitoring shall be switched off, if the current under runs 3% rated Gen‐
erator current. Refer to
ª “General notes” on page 145
and
ª “General notes”
on page 147
for details.
The df/dt monitoring (ROCOF-Relay) is now additionally applicable with Phase Shift Moni‐
toring. Refer to
ª “Phase shift” on page 172
for details.
The Q(V) monitoring function according the German grid code VDE-AR-N 4105 depends
on the parameter "phase-phase/ phase-neutral monitoring" (Even if the grid code requires
only phase/phase). Refer to
ª “General notes” on page 170
for details.
A time indication is included to inform the operator, when the device will switch into a next
operating condition, as long it is definable. Refer to
ª Chapter 5.2.4.17 “Time Indication
According To Operating Condition ” on page 444
for details.
The easYgen provides from now on LogicsManager equations to release frequency LM
00.96 and/or voltage LM 00.97 control. The operator can now from outside determine
when which control is executed.
For details refer to:
–Release f-control 12909 ª p. 341
–Release V-control 12938 ª p. 356
A dedicated LogicsManager is installed from now on to disable all mains monitoring and
the decoupling function. The mains decoupling function can be released or blocked from
outside now. Refer to
ª Chapter 4.4.2.16 “Blocking of Mains Protection” on page 183
for
details.
The change of operating mode by stopping alarms can be disabled. Refer to
1849 ª p. 216 for details.
When frequency setpoint for Digital Poti (raise/lower) is selected the start point begins
always at rated frequency.
The easYgen provides a third active power setpoint, which can be switched like setpoint 1
and 2 from outside. Refer to Setp. 3load 12998 ª p. 347 for details. (Beneficial, when
demanded VDE-AR-N 4105).
An import/export active power setpoint change follows from now on with the configurable
ramp function.
In isolated paraller operation the range of the IOP Hysteresis parameter 5761 ª p. 321 is
enhanced to start from 1 kW now.
The reactive power controller provides additionally from now on the reactive power regula‐
tion at the interchange point. Refer to
ª Chapter 4.5.12.6.1 “Control The Power Factor /
Reactive Power At The Mains Interchange Point” on page 356
for details.
Load sharing: The ramping of an engine onto others will be from now on interrupted if not
enough nominal power on the busbar is available. Refer to
ª Chapter 4.5.12.7 “Load
Share Control” on page 365
for details.
The easYgen provides from now on a voltage restraint Time Over Current Relay (ANSI 51
V). Refer to
ª Chapter 4.4.1.17 “Generator Voltage Restrained Overcurrent Monitoring -
ANSI #51” on page 149
for details.
Providing of an external mains kvar sensing (via analog input). Refer to
ª Chapter 4.2.3
“External Mains Reactive Power” on page 113
for details.
