xSpider version 3.3.10
DEMO - Generator Load Sharing
Instructional presentation
Generator Load Sharing:
All generators in project are "coupled" via controller (like ComAp
InteliGen 500, Deepsea DSE8610, ...). Required power is divided
according to generators nominal power.
New functionality available in xSpider 3.3.10 and higher
How does it work?
No controller, no load sharing
Generator Load Sharing
Required power is divided according to impedances

Generator Load Sharing:
How to use it?
1. Draw wiring diagram
(respect prerequisites and restrictions – check
next slides in this presentation).
2. Set parameters of sources and loads.
3. Set parameters of wirings, switching and
protective devices.
4. Set operation state – network must be
supplied from generators only.

6. Run “Voltage drop and load distribution”
calculation.
7. Prerequisites and restriction are checked.
8. If everything is OK calculation run through.
Results are displayed in wiring diagram.
 Simultaneous factors (Ks) are respected.
 Function has influence on load distribution
calculation only.
 Function has not any influence on shortcircuit calculation.


x If function is active, Auto Dimensioning is not
allowed.

Restrictions
If they are not met, function is ignored

1. All wires in coupling between nodes must be
"Dummy Coupling" with minor impedance.
2. Length of coupling between nodes must be
less than max allowed length.
3. All switching devices in coupling between
nodes must be switched ON.
