GENERAL PARALLELING INFORMATION (OPTION)

PARALLELING

Paralleling is the sharing of a load between two generator

sets or more.

LOAD SHARING

Load sharing is defined as the proportional division of the

and

kVAR

total load between multiple generator sets

in a paralleled system.
Load sharing is essential to avoid overloading and stability

problems on the system’s generator sets.

ACTIVE POWER (KW) LOAD SHARING

When generator sets operate in parallel, the engine speed

governor of each generator set determines the proportional

sharing of the total

active

power requirements (kW) of the

system.
The kW load sharing is achieved by increasing or decreasing

fuel to the system’s engines. As the fuel to the engine of

one generator set in a group is increased it will not lead to

an increase in speed and hence frequency (as it would if it

were operating alone) but it will lead to an increase in the
proportion of the total kW load that it will deliver.
As the fuel to the engine of one generator set in a group

is decreased it will not lead to a decrease in speed and

hence frequency (as it would if it were operating alone) but

it will lead to a decrease in the proportion of the total kW

load that it will deliver.
The control system of the generator sets (via the engine

speed control system) monitors and controls the sharing

of the total kW load in proportion to the relative rating of

the engines on the system’s generator sets.

REACTIVE POWER (KVAR) LOAD SHARING

When generator sets operate in parallel the

alternator

field excitation

system of each generator set controls

the proportional sharing of the total

reactive power

requirements (kVAR)

of the system.

NOTICE

When the paralleling option is employed, the Basler

DGC-2020HD controller

must

be installed. The

factory-installed ECU-845 controller cannot be used

for paralleling.

The kVAR load sharing is achieved by increasing or

decreasing the field excitation to the system’s alternators.
As the field excitation of one generator set in a group is

increased

(i.e. over excited) it will

not

lead to an increase

in voltage (as it would if it were operating alone) but it will

lead to an increase in the proportion of the total

kVAR

load

it will deliver and a decrease in its power factor.
As the field excitation of one generator set in a group is

decreased

(i.e. over excited) it will

not

lead to a decrease

in voltage (as it would if it were operating alone) but it will

lead to a decrease in the proportion of the total

kVAR

load

it will deliver and an increase in its power factor.
An undesirable circulating

reactive current

(cross current)

will flow in the system if the excitation of the alternators is

not matched.

ETHERNET COMMUNICATION

Ethernet communication is the preferred method for

paralleling. This method supports breaker negotiation to

avoid simultaneous breaker closures, kW load sharing and

kVAR sharing, soft load transfers, and on and off loading.
The ethernet ports are located at the output bus splash

panel area. There are two ports which are identical so

either one can be used. Using a standard ethernet cable,

inter-connect units to be paralleled and or sequenced.

LOAD MANAGEMENT

These generators are set up to automatically manage load

based on demand. Load management is only functional in

auto mode. While in

auto

mode, if the auto start contacts

are closed, load management is active by default. Load

management will only run the number of units needed to

support the load.
If the load demand is small, only one generator will remain

running while the other generators will be in standby mode.

If the load increases above 80% of its capacity, it will start

the next generator. The next generator priority is based on

the time remaining on the maintenance timer.
Generators with more time until scheduled maintenance will

take priority over units that are almost due for maintenance.

Once the second unit starts it will synchronize and parallel

in then ramp up to share the load. If the load levels drop

below 35% of its combined rating, the generator that is no

longer needed will ramp off, shut down and wait in standby

mode.
